The startup Gigablue announced with fanfare this year that it reached a historic milestone: selling 200,000 carbon credits to fund what it describes as a groundbreaking technology in the fight against climate change . But outside scientists frustrated by the lack of information released by the company say serious questions remain about whether Gigablue’s technology works as the company describes. Their questions showcase tensions in an industry built on little regulation and big promises — and a tantalizing chance to profit.

the rapid rises in global military spending threaten climate action, undermining our collective security. In a new joint paper we explore how everything from direct emissions to diverted climate finance are threatening SDG 13 on Climate action.
Militaries are huge energy users whose greenhouse gas emissions (GHG) make a significant contribution to the climate crisis. However, countries do not systematically record and report their military emissions so the real share of this source of emissions remains unclear. The Conflict and Environment Observatory (CEOBS) and Scientists for Global Responsibility estimate that everyday military activity could be responsible for around 5.5% of global emissions, meaning that if the world’s militaries were a country, they would be the fourth largest emitter in the world.6 Furthermore, as military spending increases and the rest of society decarbonises, that proportion is set to rise.

A German court has delivered a landmark ruling in a climate lawsuit brought by Peruvian farmer, Saúl Luciano Lliuya, against German energy giant RWE. The German Higher Regional Court of Hamm has ruled that, in principle, companies can be held liable to people halfway around the world for their contribution to the impacts and risks of climate change . While the Court ultimately dismissed Mr Lliuya’s claim, its reasoning represents a significant breakthrough for climate litigation globally.

Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global
An international group of researchers has produced a third update to key indicators of the state of the climate system set out in the IPCC AR6 assessment, building on previous editions in 2023 and 2024. Forster et al. (2025) assess emissions, concentrations, temperatures, energy transfers, radiation balances, and the role of human activity and conclude that, while natural climate variability also played a role, the record observed temperatures in 2024 were dominated by human activity and the remaining carbon budget for 1.5° C is smaller than ever.

In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets (published at https://doi.org/10.5281/zenodo.15639576; Smith et al., 2025a) to produce updated estimates for key indicators of the state of the climate system: net emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activities, the remaining carbon budget, and estimates of global temperature extremes. This year, we additionally include indicators for sea-level rise and land precipitation change. We follow methods as closely as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One report.
Breaching threshold would ramp up catastrophic weather events, further increasing human suffering
SO2 declines have contributed ~25% of recent warming and driven recent acceleration. The impact of additional SO2 emissions on cloud formation diminishes as emissions increase, meaning that reductions in SO2 over areas with low background sulphate concentrations, such as the ocean, could result in a proportionately larger warming effect than in highly polluted areas, such as south Asia.

Recent simulations using the Community Earth System Model (CESM) indicate that a tipping event of the Atlantic Meridional Overturning Circulation (AMOC) would cause Europe to cool by several degrees. This AMOC tipping event was found under constant pre-industrial greenhouse gas forcing, while global warming likely limits this AMOC-induced cooling response. Here, we quantify the European temperature responses under different AMOC regimes and climate change scenarios. A strongly reduced AMOC state and intermediate global warming (C, Representative Concentration Pathway 4.5) has a profound cooling effect on Northwestern Europe with more intense cold extremes. The largest temperature responses are found during the winter months and these responses are strongly influenced by the North Atlantic sea-ice extent. Enhanced North Atlantic storm track activity under an AMOC collapse results in substantially larger day-to-day temperature fluctuations. We conclude that the (far) future European temperatures are dependent o
Understanding how global mean surface temperature (GMST) has varied over the past half-billion years, a time in which evolutionary patterns of flora and fauna have had such an important influence on the evolution of climate, is essential for understanding the processes driving climate over that interval. Judd et al. present a record of GMST over the past 485 million years that they constructed by combining proxy data with climate modeling (see the Perspective by Mills). They found that GMST varied over a range from 11° to 36°C, with an “apparent” climate sensitivity of ∼8°C, about two to three times what it is today. —Jesse Smith

Under existing climate policies, global temperatures are projected to reach 2.7 degrees Celsius (4.9F) above pre-industrial levels by 2100—a pathway that would ultimately erase 76% of current glacier mass over the coming centuries. But if warming is held to the Paris Agreement's 1.5C target, 54% of glacial mass could be preserved, according to the study, which combined outputs from eight glacier models to simulate ice loss across a range of future climate scenarios.

Antarctica's remote and mysterious current has a profound influence on the climate, food systems and Antarctic ecosystems. Can we stop it weakening by 2050?
The Antarctic Circumpolar Current (ACC) is the world's strongest ocean current and plays a disproportionate role in the climate system due to its role as a conduit for major ocean basins. This current system is linked to the ocean's vertical overturning circulation, and is thus pivotal to the uptake of heat and CO2 in the ocean. The strength of the ACC has varied substantially across warm and cold climates in Earth's past, but the exact dynamical drivers of this change remain elusive. This is in part because ocean models have historically been unable to adequately resolve the small-scale processes that control current strength. Here, we assess a global ocean model simulation which resolves such processes to diagnose the impact of changing thermal, haline and wind conditions on the strength of the ACC. Our results show that, by 2050, the strength of the ACC declines by ∼20% for a high-emissions scenario. This decline is driven by meltwater from ice shelves around Antarctica, which is exported to lower latit
Critical minerals, which are essential for a range of energy technologies and for the broader economy, have become a major focus in global policy and trade discussions. Price volatility, supply chain bottlenecks and geopolitical concerns make the regular monitoring of their supply and demand extremely vital.
Earth’s albedo (reflectivity) declined over the 25 years of precise satellite data, with the decline so large that this change must be mainly reduced reflection of sunlight by clouds. Part of the cloud change is caused by reduction of human-made atmospheric aerosols, which act as condensation nuclei for cloud formation, but most of the cloud change is cloud feedback that occurs with global warming. The observed albedo change proves that clouds provide a large, amplifying, climate feedback. This large cloud feedback confirms high climate sensitivity, consistent with paleoclimate data and with the rate of global warming in the past century.

Clean-energy sectors drove a quarter of the country’s gross domestic product (GDP) growth in 2024 and have overtaken real-estate sales in value. The new sector-by-sector analysis for Carbon Brief, based on official figures, industry data and analyst reports, shows the growing role of clean technology in China’s economy – particularly the so-called “new three” industries, namely, solar, electric vehicles (EVs) and batteries.
There are four key ways of measuring energy. These metrics capture the transformations and losses that occur across the energy chain. The differences between the first stage (‘primary energy’) and the last (‘useful energy’) can be very large. This means it’s important to be clear about which metric is being referred to when people speak about data on “energy”. In this post I explain these four metrics.
Societies increasingly rely on scientists to guide decisions in times of uncertainty, from pandemic outbreaks to the rise of artificial intelligence. Addressing climate change is no different. For governments wanting to introduce ambitious climate policies, public trust in climate scientists is pivotal, because it can determine whether voters support or resist those efforts.
In this episode, I’m joined by ecologist Thomas Crowther to discuss the critical importance of biodiversity as an intricate web of life that supports all other living beings, not just through the sheer number of species, but because of the complexity of interactions within ecosystems. Thomas highlights the power of data in empowering individuals to make informed choices that positively impact nature, and the critical need to address inequality in order to foster ecological recovery.

For around 2,000 years, global sea levels varied little. That changed in the 20th century. They started rising and have not stopped since — and the pace is accelerating. Scientists are scrambling to understand what this means for the future just as President Trump strips back agencies tasked with monitoring the oceans.
The ocean ecosystem is a vital component of the global carbon cycle, storing enough carbon to keep atmospheric CO2 considerably lower than it would otherwise be. However, this conception is based on simple models, neglecting the coupled land-ocean feedback. Using an interactive Earth system model, we show that the role ocean biology plays in controlling atmospheric CO2 is more complex than previously thought. Atmospheric CO2 in a new equilibrium state after the biological pump is shut down increases by more than 50% (163 ppm), lower than expected as approximately half the carbon lost from the ocean is adsorbed by the land. The abiotic ocean is less capable of taking up anthropogenic carbon due to the warmer climate, an absent biological surface pCO2 deficit and a higher Revelle factor. Prioritizing research on and preserving marine ecosystem functioning would be crucial to mitigate climate change and the risks associated with it.
Have you ever thought about what would happen if all life in the ocean disappeared? A recent study explores this extreme scenario to understand how ocean biology shapes the past, present, and future climate. The ocean plays a critical role in regulating Earth's climate. It is a massive carbon store that absorbs about 25% of human-caused emissions and thus helps maintain a relatively low CO2 level in the atmosphere. But what would happen if all marine life—from the tiniest plankton to the largest whales—disappeared? A recent study delves into this extreme scenario to uncover the crucial role that ocean biology plays in mitigating climate change.

Study Finds Synergistic Convergence of Global Warming, Pesticide Toxicity, and Antibiotic Resistance
(01/05) - Beyond PesticidesSpringtails illustrate in new research how global warning and antibiotic resistance creates synergistic effects: warming increases pesticide toxicity, triggering antibiotic resistance which spreads through horizontal gene transfer and predation.
The escalating tensions between Pakistan and India serve as a stark reminder that climate change is no longer a distant — it is now a force multiplier for geopolitical instability. As the climate crisis accelerates, so too does its capacity to deepen existing rivalries, strain fragile agreements, and inflame long-standing disputes. In South Asia, the Indus Waters Treaty (IWT) has long been a rare success story of transboundary cooperation between two nuclear-armed neighbours. However, as both climate pressures and political tensions mount, this once-resilient agreement is beginning to show signs of severe strain. The looming question is no longer just about water rights — it’s about whether climate change could be the catalyst for the world’s first true climate war.
In thinking about the war being waged against life on Earth by Donald Trump, Elon Musk and their minions, I keep bumping into a horrible suspicion. Could it be that this is not just about delivering the world to oligarchs and corporations – not just about wringing as much profit from living systems as they can? Could it be that they want to see the destruction of the habitable planet?
The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024. The researchers also found the tiny particles in liver and kidney samples.

2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees Celsius above the preindustrial level, another record.A team led by the Alfred Wegener Institute puts forward a possible explanation for the rise in global mean temperature: our planet has become less reflective because certain types of clouds have declined. The work is published in the journal Science.
Carbon emissions may continue to rise, the polar ice caps may continue to melt, crop yields may continue to decline, the world’s forests may continue to burn, coastal cities may continue to sink under rising seas and droughts may continue to wipe out fertile farmlands, but the messiahs of hope assure us that all will be right in the end. Only it won’t.” — Chris Hedges
Growing food is a precarious business, and losing access to key information makes it worse.
It is said that George W. Bush Jr. decided to invade Iraq in 2003 because he had read some papers on oil depletion by the Association for the Study of Peak Oil (ASPO). Of course, it may be just a legend, but I don’t see it as impossible, and perhaps not even improbable. Politicians make decisions on the basis of vague ideas, often on the spur of the moment, and in many cases making terrible mistakes. But they normally understand some of the critical elements that keep alive the system. For the US, the critical resource was, and still is, crude oil. So, it is possible that Bush thought that it was necessary to compensate for the decline of the US oil production by seizing the Iraqi resources. That didn’t necessarily imply to start a war, just like filling the tank of your car doesn’t imply shooting dead the service station operator. But that’s the way some people’s minds work.
We develop roadmaps to transform the all-purpose energy infrastructures (electricity, transportation, heating/cooling, industry, agriculture/forestry/fishing) of 139 countries to ones powered by wind, water, and sunlight (WWS). The roadmaps envision 80% conversion by 2030 and 100% by 2050. WWS not only replaces business-as-usual (BAU) power, but also reduces it ∼42.5% because the work: energy ratio of WWS electricity exceeds that of combustion (23.0%), WWS requires no mining, transporting, or processing of fuels (12.6%), and WWS end-use efficiency is assumed to exceed that of BAU (6.9%). Converting may create ∼24.3 million more permanent, full-time jobs than jobs lost. It may avoid ∼4.6 million/year premature air-pollution deaths today and ∼3.5 million/year in 2050; ∼$22.8 trillion/year (12.7 ¢/kWh-BAU-all-energy) in 2050 air-pollution costs; and ∼$28.5 trillion/year (15.8 ¢/kWh-BAU-all-energy) in 2050 climate costs. Transitioning should also stabilize energy prices because fuel costs are zero, reduce power d
A superpower in the fight against global heating is hiding in plain sight. It turns out that the overwhelming majority of people in the world – between 80% and 89%, according to a growing number of peer-reviewed scientific studies – want their governments to take stronger climate action.
Metals and metalloids are ubiquitous in soils, originating from bedrock and from human activities and infrastructure. These compounds can be toxic to humans and other organisms, and their soil distribution and concentrations at global scale are not well known. Hou et al. analyzed data from more than 1000 regional studies to identify areas of metal toxicity and explore drivers of these trends. They estimate that 14 to 17% of cropland exceeds agricultural thresholds for at least one toxic metal.
For hundreds of millions of people living in India and Pakistan the early arrival of summer heatwaves has become a terrifying reality that’s testing survivability limits and putting enormous strain on energy supplies, vital crops and livelihoods. Both countries experience heatwaves during the summer months of May and June, but this year’s heatwave season has arrived sooner than usual and is predicted to last longer too. Temperatures are expected to climb to dangerous levels in both countries this week.

Do civilizations have tipping points that determine their rise and fall? Untangling how and why civilizations fall could, in theory, help humanity avoid a future calamitous collapse. “The reason why complex societies disintegrate is of vital importance to every member of one, and today that includes nearly the entire world population,” Tainter wrote. “Whether or not collapse was the most outstanding event of ancient history, few would care for it to become the most significant event of the present era.”
A Dartmouth College research team came up with the estimated pollution caused by 111 companies, with more than half of the total dollar figure coming from 10 fossil fuel providers: Saudi Aramco, Gazprom, Chevron, ExxonMobil, BP, Shell, National Iranian Oil Co., Pemex, Coal India and the British Coal Corporation. For comparison, $28 trillion is a shade less than the sum of all goods and services produced in the United States last year.
Recent projections suggest that large geographical areas will soon experience heat and humidity exceeding limits for human thermoregulation. The survivability limits modeled in that research were based on laboratory studies suggesting that humans cannot effectively thermoregulate in wet bulb temperatures (Twb) above 26 to 31 °C, values considerably lower than the widely publicized theoretical threshold of 35 °C. The newly proposed empirical limits were derived from the Twb corresponding to the core temperature inflection point in participants exposed to stepped increases in air temperature or relative humidity in a climate-controlled chamber. Despite the increasing use of these thermal-step protocols, their validity has not been established. We used a humidity-step protocol to estimate the Twb threshold for core temperature inflection in 12 volunteers.
Land degradation is a complex socio-environmental threat, which generally occurs as multiple concurrent pathways that remain largely unexplored in Europe. Here we present an unprecedented analysis of land multi-degradation in 40 continental countries, using twelve dataset-based processes that were modelled as land degradation convergence and combination pathways in Europe’s agricultural (and arable) environments. Using a Land Multi-degradation Index, we find that up to 27%, 35% and 22% of continental agricultural (~2 million km2) and arable (~1.1 million km2) lands are currently threatened by one, two, and three drivers of degradation, while 10–11% of pan-European agricultural/arable landscapes are cumulatively affected by four and at least five concurrent processes. We also explore the complex pattern of spatially interacting processes, emphasizing the major combinations of land degradation pathways across continental and national boundaries. Our results will enable policymakers to develop knowledge-based st
Pesticides affect a diverse range of non-target species and may be linked to global biodiversity loss. The magnitude of this hazard remains only partially understood. We present a synthesis of pesticide (insecticide, herbicide and fungicide) impacts on multiple non-target organisms across trophic levels based on 20,212 effect sizes from 1,705 studies. For non-target plants, animals (invertebrate and vertebrates) and microorganisms (bacteria and fungi), we show negative responses of the growth, reproduction, behaviour and other physiological biomarkers within terrestrial and aquatic systems. Pesticides formulated for specific taxa negatively affected non-target groups, e.g. insecticidal neonicotinoids affecting amphibians. Negative effects were more pronounced in temperate than tropical regions but were consistent between aquatic and terrestrial environments, even after correcting for field-realistic terrestrial and environmentally relevant exposure scenarios. Our results question the sustainability of current
Atrazine is an herbicide widely used on plantations worldwide. Experimental studies suggest that the herbicide impairs male reproductive function in mammals. This systematic review and meta-analysis aimed to evaluate the impact of atrazine exposure on the levels of hormones from the hypothalamic-pituitary-testicular axis using murine as the animal model. After an extensive literature search, we selected 25 articles for the systematic review.
Microplastics have been found for the first time in human ovary follicular fluid, raising a new round of questions about the ubiquitous and toxic substances’ potential impact on women’s fertility. The new peer-reviewed research published in Ecotoxicology and Environmental Safety checked for microplastics in the follicular fluid of 18 women undergoing assisted reproductive treatment at a fertility clinic in Salerno, Italy, and detected them in 14.
Climate experts expressed shock and dismay at the move. “It would be a bit like unplugging the equipment that monitors the vital signs of a patient that is critically ill,” one said.
Global temperature for 2025 should decline little, if at all, from the record 2024 level. Absence of a large temperature decline after the huge El Nino-spurred temperature increase in 2023-24 will provide further confirmation that IPCC’s best estimates for climate sensitivity and aerosol climate forcing were both underestimates. Specifically, 2025 global temperature should remain near or above +1.5C relative to 1880-1920, and, if the tropics remain ENSO-neutral, there is good chance that 2025 may even exceed the 2024 record high global temperature.
Tipping elements within the Earth system are increasingly well understood. Scientists have identified more than 25 parts of the Earth’s climate system that are likely to have “tipping points” – thresholds where a small additional change in global warming will cause them to irreversibly shift into a new state. The “tipping” of these systems – which include the Atlantic Meridional Overturning Circulation (AMOC), the Amazon rainforest and the Greenland ice sheet – would have profound consequences for both the biosphere and people. More recent research suggests that triggering one tipping element could cause subsequent changes in other tipping elements, potentially leading to a “tipping cascade”. For example, a collapsed AMOC could lead to dieback of the Amazon rainforest and hasten the melt of the Greenland ice sheet.
Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

If the global consumption of fossil fuels continues to grow at its present rate, atmospheric CO2 content will double in about 50 years. Climatic models suggest that the resultant greenhouse-warming effect will be greatly magnified in high latitudes. The computed temperature rise at lat 80° S could start rapid deglaciation of West Antarctica, leading to a 5 m rise in sea level.

Greenpeace lost – not because it did something wrong but because it was denied a fair trial The stunning $667m verdict against Greenpeace last week is a direct attack on the climate movement, Indigenous peoples and the first amendment. The North Dakota case is so deeply flawed – at its core, the trial was really about crushing dissent – that I believe there is a good chance it will be reversed on appeal and ultimately backfire against the Energy Transfer pipeline company.

While NGOs and Members of the European Parliament are calling for a ban on so-called "forever chemicals" in pesticides, only a few kilometres from Brussels, in Flanders, contamination is in full swing, even affecting organic farmers. PFAS (per- and polyfluoroalkyl substances) are chemicals used mainly for their water-repellent properties. Recent studies suggest that pesticide products may contain PFAS and that some active ingredients may meet the definition of a PFAS. This group of chemicals is a known threat to human health. Once in the environment, they are extremely persistent, earning them the nickname "forever chemicals".
Major mapping project reveals PFAS have been found at high levels at thousands of sites across Europe. EURACTIV's media partner, The Guardian, reports. Pollutants known as “forever chemicals”, which don’t break down in the environment, build up in the body and may be toxic, have been found at high levels at thousands of sites across the UK and Europe, a major mapping project has revealed.
The multibillion-dollar chemicals company 3M told customers its firefighting foams were harmless and biodegradable when it knew they contained toxic substances so persistent they are now known as “forever chemicals” and banned in many countries including the UK, newly uncovered documents show.
The clear signs of human-induced climate change reached new heights in 2024, which was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average.
Our study presents a global assessment of microplastic pollution’s impact on food security. By analyzing a comprehensive dataset of 3,286 records, we quantify the reduction in photosynthesis caused by microplastics across various ecosystems.
Countries must move rapidly to slash CO2 emissions from homes, offices, shops and other buildings—a sector that accounts for a third of global greenhouse gas pollution, the United Nations said Monday. Carbon dioxide emissions from the building sector rose around 5% in the last decade when they should have fallen 28%, according to a new report by the United Nations Environment Program (UNEP).
We must learn from the past. We cannot remain silent in the face of authoritarian attacks on our peers, even if they have not yet come for us.
Global sea level rose faster than expected in 2024, mostly because of ocean water expanding as it warms, or thermal expansion. According to a NASA-led analysis, last year’s rate of rise was 0.23 inches (0.59 centimeters) per year, compared to the expected rate of 0.17 inches (0.43 centimeters) per year.
As if there was any doubt, we can go ahead and officially add climate change to the list of things that we can’t count on billionaires to figure out for us. According to the New York Times, Breakthrough Energy, a joint venture between Bill Gates and a handful of other billionaires who at least nominally care about the environment, is laying off a significant portion of its staff, which will likely neuter its capability to lobby and influence policy.
Donald Trump has ordered that swathes of America’s forests be felled for timber, evading rules to protect endangered species while doing so and raising the prospect of chainsaws razing some of the most ecologically important trees in the US. The president, in an executive order, has demanded an expansion in tree cutting across 280m acres (113m hectares) of national forests and other public lands, claiming that “heavy-handed federal policies” have made America reliant on foreign imports of timber.
His Royal Highness King Godwin Bebe Okpabi has carried bottles of water drawn from the wells of his homeland in the Niger delta to the high court in London. For the past three and a half weeks, lawyers for Shell have argued at the high court that their client cannot be held responsible for an environmental catastrophe in Ogale, which has suffered from decades of spills and pollution from oil extraction.
Published 1972 – The message of this book still holds today: The earth’s interlocking resources – the global system of nature in which we all live – probably cannot support present rates of economic and population growth much beyond the year 2100, if that long, even with advanced technology. In the summer of 1970, an international team of researchers at the Massachusetts Institute of Technology (MIT) began a study of the implications of continued worldwide growth. They examined the five basic factors that determine and, in their interactions, ultimately limit growth on this planet-population increase, agricultural production, nonrenewable resource depletion, industrial output, and pollution generation. The MIT team fed data on these five factors into a global computer model and then tested the behaviour of the model under several sets of assumptions to determine alternative patterns for humankind’s future. The Limits to Growth is the nontechnical report of their findings. The book contains a message of hope a

As fossil fuel interests attack climate accountability litigation, environmental advocates have sounded a new warning that they are pursuing a path that would destroy all future prospects for such cases. Nearly 200 advocacy groups have urged Democratic representatives to “proactively and affirmatively” reject potential industry attempts to obtain immunity from litigation.
Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.

Last month was the hottest January on record, blitzing the previous high and stunning climate scientists who expected cooler La Niña conditions to finally start quelling a long-running heat streak. The Copernicus Climate Change Service said January was 1.75C hotter than pre-industrial times, extending a persistent run of historic highs over 2023 and 2024, as human-caused greenhouse gas emissions heat the planet.
A new analysis shows the world's oceans were the warmest in 2019 than any other time in recorded human history, especially between the surface and a depth of 2,000 meters. The study, conducted by an international team of 14 scientists from 11 institutes across the world, also concludes that the past 10 years have been the warmest on record for global ocean temperatures, with the past five years holding the highest record.

The researchers estimated an extra 8,000 people would die each year as a result of “suboptimal temperatures” even under the most optimistic scenario for cutting planet-heating pollution. The hottest plausible scenario they considered showed a net increase of 80,000 temperature-related deaths a year.
n the UK, when climate activists want to block a road, they sit down on it. When their fellow activists in France want to do the same, they build a wall across one side, and set the other side on fire.

A new report from U.K. actuaries and climate scientists "shows a 50% GDP contraction between 2070 and 2090 unless an alternative course is chartered," said the lead author.
A new report explores a framework for global climate risk management and includes contributions from an actuary at the Government Actuary's Department.
For years, climate scientists have warned us of rising temperatures, extreme weather, and ecological breakdown. Now, the very people who calculate financial risk—actuaries—are sounding the alarm. Their latest report projects a 50% collapse in global GDP within decades. That’s not a recession. That’s economic devastation on a scale we’ve never seen.

Reintroducing wolves to the Scottish Highlands could lead to an expansion of native woodland which could take in and store one million tonnes of CO2 annually, according to a new study.
This new research, written over four years and published in Reviews of Geophysics, finds that the true climate sensitivity is unlikely to be in the lowest part of the 1.5-4.5°C range. The analysis indicates that if atmospheric carbon dioxide levels double from their pre-industrial levels and are maintained, the world would probably experience eventual warming from 2.3 – 4.5°C. The researchers found there would be less than 5% chance of staying below 2°C and a 6-18% chance of exceeding 4.5°C.
Climate change will fuel contests—and maybe wars—for land and resources.
The world is warming despite natural fluctuations from the El Niño cycle.
Global temperature leaped more than 0.4°C (0.7°F) during the past two years, the 12-month average peaking in August 2024 at +1.6°C relative to the temperature at the beginning of last century (the 1880-1920 average). This temperature jump was spurred by one of the periodic tropical El Niño warming events, but many Earth scientists were baffled by the magnitude of the global warming, which was twice as large as expected for the weak 2023-2024 El Niño.

The students behind the Stand Up for Science protests
Amid President Donald Trump’s attacks on government scientists and science funding, researchers are arranging rallies to “Stand Up for Science” in Washington, D.C., and nationwide on March 7
The March for Science (formerly known as the Scientists' March on Washington)[6] was an international series of rallies and marches held on Earth Day. The inaugural march was held on April 22, 2017, in Washington, D.C., and more than 600 other cities across the world.[7][8][9][10][11] According to organizers, the march was a non-partisan movement to celebrate science and the role it plays in everyday lives.[12] The goals of the marches and rallies were to emphasize that science upholds the common good and to call for evidence-based policy in the public's best interest.[11][13] The March for Science organizers, estimated global attendance at 1.07 million, with 100,000 participants estimated for the main March in Washington, D.C., 70,000 in Boston, 60,000 in Chicago, 50,000 in Los Angeles, 50,000 in San Francisco,[14] 20,000 in Seattle, 14,000 in Phoenix, and 11,000 in Berlin.[15]

Thirteen of the ports with the highest supertanker traffic will be seriously damaged by just 1 metre of sea level rise, the analysis found. The researchers said two low-lying ports in Saudi Arabia – Ras Tanura and Yanbu – were particularly vulnerable. Both are operated by Aramco, the Saudi state oil firm, and 98% of the country’s oil exports leave via these ports.
... An “acid” test of our interpretation will be provided by the 2025 global temperature: unlike the 1997-98 and 2015-16 El Ninos, which were followed by global cooling of more than 0.3°C and 0.2°C, respectively, we expect global temperature in 2025 to remain near or above the 1.5°C level. Indeed, the 2025 might even set a new record despite the present weak La Nina. There are two independent reasons. First, the “new” climate forcing due to reduction of sulfate aerosols over the ocean remains in place, and, second, high climate sensitivity (~4.5°C for doubled CO2) implies that the warming from recently added forcings is still growing significantly.
The economic damage wrought by climate change is six times worse than previously thought, with global heating set to shrink wealth at a rate consistent with the level of financial losses of a continuing permanent war, research has found. A 1C increase in global temperature leads to a 12% decline in world gross domestic product (GDP), the researchers found, a far higher estimate than that of previous analyses.

An international group of scientists, led by King's College London, has revealed how continued global warming will lead to more parts of the planet becoming too hot for the human body over the coming decades. the amount of landmass on our planet that would be too hot for even healthy young humans (18 to 60-year-olds) to keep a safe core body temperature will approximately triple (to 6%)—an area almost the size of the US—if global warming reaches 2°C above the preindustrial average.

The 20th edition of the Global Risks Report 2025 reveals an increasingly fractured global landscape, where escalating geopolitical, environmental, societal and technological challenges threaten stability and progress. This edition presents the findings of the Global Risks Perception Survey 2024-2025 (GRPS), which captures insights from over 900 experts worldwide. The report analyses global risks through three timeframes to support decision- makers in balancing current crises and longer-term priorities.
Human-caused climate change increased the likelihood and intensity of the hot, dry and windy conditions that fanned the flames of the recent devastating Southern California wildfires, a scientific study found. But the myriad of causes that go into the still smoldering fires are complex, so the level of global warming's fingerprints on weeks of burning appears relatively small compared to previous studies of killer heat waves, floods and droughts by the international team at World Weather Attribution. Tuesday's report, too rapid for peer-review yet, found global warming boosted the likelihood of high fire weather conditions in this month's fires by 35% and its intensity by 6%.
Previous health impact assessments of temperature-related mortality in Europe indicated that the mortality burden attributable to cold is much larger than for heat. Questions remain as to whether climate change can result in a net decrease in temperature-related mortality. In this study, we estimated how climate change could affect future heat-related and cold-related mortality in 854 European urban areas, under several climate, demographic and adaptation scenarios. We showed that, with no adaptation to heat, the increase in heat-related deaths consistently exceeds any decrease in cold-related deaths across all considered scenarios in Europe. Under the lowest mitigation and adaptation scenario (SSP3-7.0), we estimate a net death burden due to climate change increasing by 49.9% and cumulating 2,345,410 (95% confidence interval = 327,603 to 4,775,853) climate change-related deaths between 2015 and 2099. This net effect would remain positive even under high adaptation scenarios, whereby a risk attenuation of 50%
There are increasing concerns that continued economic growth in high-income countries might not be environmentally sustainable, socially beneficial, or economically achievable. In this Review, we explore the rapidly advancing field of post-growth research, which has evolved in response to these concerns. The central idea of post-growth is to replace the goal of increasing GDP with the goal of improving human wellbeing within planetary boundaries. Key advances discussed in this Review include: the development of ecological macroeconomic models that test policies for managing without growth; understanding and reducing the growth dependencies that tie social welfare to increasing GDP in the current economy; and characterising the policies and provisioning systems that would allow resource use to be reduced while improving human wellbeing. Despite recent advances in post-growth research, important questions remain, such as the politics of transition, and transformations in the relationship between the Global Nort
In 1919, at the height of a global crisis that resulted from the turmoil of the Russian Revolution, the devastation of the first world war, and the collapse of Europe’s great continental empires, Irish writer William Butler Yeats penned his famed warning to humanity, mourning the end of the old world: “Things fall apart; the centre cannot hold / Mere anarchy is loosed upon the world.”

The world could fall short of food by 2050 due to falling crop yields, insufficient investment in agricultural research and trade shocks, according to Joe Biden’s special envoy for food security, Dr Cary Fowler. Fowler, who is also known as the “father” of the Svalbard Global Seed Vault, a global store of seeds for the most significant crops, said studies by agricultural economists showed the world needed to produce 50-60% more food by 2050 in order to feed its growing population. But crop yields rates were projected to decline by between 3-12% as a result of global heating.

Clouds play an important role in how much the Earth warms when greenhouse gases like carbon dioxide increase. However, scientists have struggled to determine whether low-level clouds in the tropics slow down or speed up global warming, creating uncertainty in climate predictions. A new study published in Nature adds to the growing evidence that cloud feedback is very likely to amplify warming in the climate system, rather than reduce it.

In a press release, the group, which calls itself Shut the System, said it had targeted insurers “due to their critical role underpinning the fossil fuel economy through underwriting contracts and investments”.
While some progress has been made in limiting greenhouse gas emissions, we are still on the path for high levels of global warming
Climate change will cause agricultural failure and subsequent collapse of hyperfragile modern civilization, likely within 10–15 years. By 2050 total human population will likely be under 2 billion. Humans, along with most other animals, will go extinct before the end of this century. These impacts are locked in and cannot be averted. Everything in this article is supporting information for this conclusion.
The only publication for climate action, covering the environment, biodiversity, net zero, renewable energy and regenerative approaches. It’s time for The New Climate.
Thoughts on the Collapse of Civilization
The CIO of Goldman Sachs has said that in the next year, companies at the forefront will begin to use AI agents as if they were employees — as team members with tasks to do.
Limiting global temperature rise to 1.5 degrees C is essential for avoiding the worst climate change impacts, but doing so requires cutting emissions 42% by 2030 and 56% by 2035. Current policies alone will achieve less than a 1% reduction.
A new study suggests that the Gulf Stream was stronger during the last ice age due to more powerful winds, indicating that future changes in wind patterns could weaken the Gulf Stream, affecting European climate and North American sea levels. This research enhances our understanding of the Atlantic Meridional Overturning Circulation (AMOC) and its vulnerability to climate change.
Thousands of Greenland's crystal-clear blue lakes have turned a murky brown thanks to global warming — and the worst part is that they've started emitting carbon dioxide. Record heat and rain in 2022 pushed the lakes of West Greenland past a tipping point, so rather than absorbing carbon dioxide (CO₂), they began to emit it into the atmosphere, according to a new study.
NASA satellites discovered that Earth's surface has lost enough water to empty Lake Erie two and a half times since 2015. And the problem could be here to stay.
Climate projections versus population projections - There is a puzzling disconnect at the core of climate science between climate projections and population projections. Indeed, comparing the two, one might be forgiven for thinking that population scientists and climate scientists live in two completely different worlds.
The collapse of civilization is becoming very obvious, yet most people still don't know. Here are three reasons why.
Now that humans have overshot the carrying capacity of the planet, collapse is inevitable no matter what we do.
Knowing that the world is ending can be incredibly lonely. Here's what it's like to be collapse aware among those who are oblivious.
As authorities declared 2024 the hottest on record, a key private sector climate alliance, the Glasgow Financial Alliance for Net Zero (GFANZ) abandoned a requirement that members be aligned to the Paris agreement. That was followed by a network of net zero asset managers suspending work, and deleting from its website its statement of commitments that members must adopt, after BlackRock, the biggest of them all, quit its ranks.
Emerging infectious diseases, biodiversity loss, and anthropogenic environmental change are interconnected crises with massive social and ecological costs. In this Review, we discuss how pathogens and parasites are responding to global change, and the implications for pandemic prevention and biodiversity conservation. Ecological and evolutionary principles help to explain why both pandemics and wildlife die-offs are becoming more common; why land-use change and biodiversity loss are often followed by an increase in zoonotic and vector-borne diseases; and why some species, such as bats, host so many emerging pathogens. To prevent the next pandemic, scientists should focus on monitoring and limiting the spread of a handful of high-risk viruses, especially at key interfaces such as farms and live-animal markets. But to address the much broader set of infectious disease risks associated with the Anthropocene, decision-makers will need to develop comprehensive strategies that include pathogen surveillance across s
Natural sinks of forests and peat were key to Finland’s ambitious target to be carbon neutral by 2035. But now, the land has started emitting more greenhouse gases than it stores
Wildfires that blazed around the world in 2024 helped to drive a record annual leap in carbon dioxide levels in the atmosphere, surprising scientists. The data shows humanity is moving yet deeper into a dangerous world of supercharged extreme weather.

‘Net zero hero’ myth unfairly shifts burden of solving climate crisis on to individuals, study finds
(19/01) - Guardian staff reporterShifting responsibility to consumers minimises the role of energy industry and policymakers, University of Sydney research suggests
Britain’s crackdown on climate protest is setting “a dangerous precedent” around the world and undermining democratic rights, the UK director of Human Rights Watch has said. In the UK “laws criminalising protests undermine democratic rights”, the NGO says in its latest annual world report, published on Thursday, adding that in the past year “the UK continued to crack down on and criminalise climate protests”.
Experts believe H5N1 bird flu belongs in a growing category of infectious diseases that can cause pandemics across many species. But there are ways to reduce the risks..
Firms are flocking to invest in geoengineering projects. Could such startups turn a profit by preventing climate peril? Luke Iseman is emboldened by all the criticism, personal attacks and negative press he has received. This article is guilty of feeding into that feedback loop — of lending some legitimacy to what he’s done. Many of the world’s atmospheric scientists will say this is dangerous, and they’re probably right.
Actuaries are calling for more realistic climate risk assessments. This includes the “risk of ruin”: the point past which global society can no longer adapt to climate change. Today’s report from the Institute and Faculty of Actuaries (IFoA) and the University of Exeter – “Climate Scorpion: the sting is in the tail” – puts forward the case for using financial services risk management to evaluate and communicate climate risk. It advocates for “worst-case” scenario thinking around climate change.
And what we need to do it right,
Companies announce climate goals with great fanfare—but all too often, they eventually scale back or fail to implement those pledges. We asked Yale SOM’s Todd Cort how significant these reversals are and what should be done to encourage companies to keep making progress.
On the topic of climate and carbon reduction commitments, corporations like Google, Microsoft, and Shell once positioned themselves as leaders in sustainability, setting ambitious net-zero goals to align with global environmental efforts. However, the rapid rise of energy-hungry artificial intelligence is forcing these companies to reconsider—or even abandon—these commitments as they struggle to balance environmental responsibility and making money from new tech.
British police arrest environmental protesters at nearly three times the global average rate, research has found, revealing the country as a world leader in the legal crackdown on climate activism.
Campaigners receive longest ever sentences for non-violent protest after being convicted of conspiracy to cause public nuisance
The abrupt loss of many species from a system is generally attributed to a breakdown in ecological functioning. As species are sequentially knocked out, the whole community becomes unstable, and it all comes crashing down. Another mechanism that may be at play. My colleagues and I argue that despite the fact life on Earth displays such great variety, many species that live together appear to share remarkably similar thermal limits. That is to say, individuals of different species can tolerate temperatures up to similar points.
As human fragility is stretched towards breaking point, should we be preparing for societal collapse? This is the existential question behind ‘deep adaptation’, a theory that is rapidly gaining adherents. Richard Swift assesses how far, if anywhere, it will take us and what better paths we could go down.
It’s better to burn out than fade away…until it kills you.
The masses cry out for immediate solutions to long-term problems, inviting despots to lead them.
Why governmental climate plans are a complete joke.
Global warming is moving faster than the best models can keep a handle on.
When it comes to writing about climate change … or energy transition … or resource depletion … the new “it” word seems to be COLLAPSE. Collapse is everywhere. But collapse is an inherently fuzzy…
As an average citizen of the United States, one with no particular power over our political trajectory beyond my ability to vote and encourage others to vote, I have very little say in how our descent into a hotter, resource-depleted world will play out. This contrasts with how much I worry about that impending descent, its impact on my children and grandchildren, and its deep implications for the future of humanity writ large.
Every December, people ask us how severe the year’s extreme weather events were. To answer this question, we’ve partnered with Climate Central to produce a report that reviews some of the most significant events and highlights findings from our attribution studies. It also includes new analysis looking at the number of dangerous heat days added by climate change in 2024 and global resolutions for 2025 to work toward a safer, more sustainable world.
Au milieu des années 1990, la population de vautours, forte de 50 millions d'individus, s'est effondrée, au point de devenir presque nulle, à cause du diclofénac, un analgésique non stéroïdien bon marché utilisé pour le bétail, mais qui est fatal aux vautours. Une nouvelle étude établit un lien entre le déclin des vautours en Inde et la propagation d'une bactérie mortelle, à l'origine de quelque 500 000 décès.
The year 2024 wasn’t just another chapter in the unfolding climate saga; it felt like the plot twist no one wanted to believe. For decades, climate scientists warned of ifs — if we pass this tipping…
To date, the ocean has largely been treated as an afterthought in global climate strategies, sidelined in favor of more visible priorities like renewable energy and reducing carbon emissions. But ocean-based solutions are indispensable to the green transition and must be funded accordingly.
Several high-profile research papers have brought renewed attention to the potential collapse of a crucial system of ocean currents known as the Atlantic Meridional Overturning Circulation, or AMOC, as we discussed in part one of this two-part post. Huge uncertainties in both the timing and details of potential impacts of such a collapse remain.
Japan has doubled down on the nuclear industry’s routine practice of spreading radioactive pollutants to public air space and to common waterways. In addition to the pumping of tens of thousands of tons of radioactively contaminated cooling water to the Pacific Ocean from the Fukushima-Daiichi reactor complex, the government has announced its intention to spread around the country as much as 14 million cubic meters of radioactively contaminated soil, reportedly for road-building, construction projects, and even agricultural underlayment.
EPFL scientists developed a tool to evaluate climate models, revealing that some predict a much hotter future due to high carbon sensitivity, suggesting current emission reduction efforts may be inadequate.
I mapped out a likely scenario, based on a synthesis of a variety of estimates combined with a dose of interpretation. While I can't predict the future, if we continue business as usual we'll soon witness compounding destruction of our infrastructure, economy and agricultural systems. A reasonable estimate suggests cascading civilizational and social collapses by mid-century - just 25 years from now.
In this article, we’ll see why cascading disruptions of environmental and political systems are entangled and mutually reinforcing. We’ll also try to identify the next stages of global collapse, and explore the options for individuals and communities seeking to survive and to prevent as much harm and suffering as possible.
Sea ice extent for the Arctic overall as of mid-December is at the lowest for this point in the season in the entire satellite era record (since autumn 1978) Whether this is a transient low extent or not, expanded open water now, with the winter solstice upon us, means that there’s less time for ice, once it forms, to thicken up before the spring melt commences in a few months.
Over 2.5 billion people depend on aquifers for fresh water, but rising seas and climate change are pushing saltwater into these crucial reserves.
In this week’s Down To Earth newsletter: The global crackdown against climate activists and groups is clearly part of the fossil fuel industry’s strategy to crush dissent and keep burning the planet
Depleted soil leads to reduced yields, forcing farmers to rely on fertilizers that raise food production costs, consumer prices.
At least 1773 fossil fuel lobbyists have been granted access to the COP29 summit in Baku, underscoring an outsized polluter presence year after year at crucial climate talks, according to a new analysis from Corporate Europe Observatory, Corporate Accountability and Global Witness, from the Kick Big Polluters Out (KBPO) coalition.
COP29 in Baku, which finished last week, was crawling with fossil-fuel lobbyists determined to eke out profits for as long as possible. Shockingly, for a second year running, it is European governments that have facilitated access for a huge number of them.
Microplastics and nanoplastics may be present in food, primarily from environmental contamination where foods are grown or raised.
Microplastics are ubiquitous environmental contaminants for which there are documented human exposures, but there is a paucity of research evaluating their impacts on human health. We conducted a rapid systematic review using the “Navigation Guide” systematic review method. We searched four databases in July 2022 and April 2024 with no restriction on the date.
Jem Bendell encourages us to think about societal collapse in ways that are ‘profound and startlingly original’, with the potential to birth whole new social movements, says Tom Doig.
The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions. ...
Hastened reviews of compounds as industry ramps up could increase pollution from likely toxic chemicals.

President formally files new plans under Paris agreement and hails ‘boldest climate agenda in American history’. Joe Biden has announced tougher targets on the US’s carbon dioxide emissions for the next decade, in a defiant final gesture intended as a “capstone” on his legacy on the climate. With just weeks to go before Donald Trump enters the White House, the Biden administration is formally filing new plans under the Paris agreement – the global climate treaty from which Trump has vowed to withdraw.
As the world’s largest gathering of Earth and space scientists swarmed a Washington venue last week, the packed halls have been permeated by an air of anxiety and even dread over a new Donald Trump presidency that might worsen what has been a bruising few years for science.
Experts warn that mirror bacteria, constructed from mirror images of molecules found in nature, could put humans, animals and plants at risk of lethal infections
This report describes the technical feasibility of creating mirror bacteria and the potentially serious and wide-ranging risks that they could pose to humans, other animals, plants, and the environment. It accompanies the Science Policy Forum article titled “Confronting risks of mirror life”, published December 12, 2024.
All known life is homochiral. DNA and RNA are made from “right-handed” nucleotides, and proteins are made from “left-handed” amino acids. Driven by curiosity and plausible applications, some researchers had begun work toward creating lifeforms composed entirely of mirror-image biological molecules. Such mirror organisms would constitute a radical departure from known life, and their creation warrants careful consideration. The capability to create mirror life is likely at least a decade away and would require large investments and major technical advances; we thus have an opportunity to consider and preempt risks before they are realized. Here, we draw on an in-depth analysis of current technical barriers, how they might be eroded by technological progress, and what we deem to be unprecedented and largely overlooked risks (1). We call for broader discussion among the global research community, policy-makers, research funders, industry, civil society, and the public to chart an appropriate path forward.
Among the many things global warming will be melting this century—sea ice, land glaciers and tourist businesses in seaside towns across the world—is permafrost. Lying underneath 15% of the northern hemisphere, permafrost consists of accumulating dead biomass that remains frozen, never having had a chance to release all its carbon.
A short definition of the polycrisis, including global environmental, geopolitical, and economic aspects.
In the lead-up to COP29, Fausto Corvino emphasized the need for a paradigm shift within the international climate negotiations to ensure that the global rich bear a greater responsibility for climate finance. In this follow-up article, he explains why COP29 has failed in its historic mission to lay the foundations for a rapid and equitable global transition to low-carbon energy....
Aridité : une crise existentielle pour la vie sur TerreCinq milliards de personnes pourraient être touchées d'ici 2100. Malgré l'intensification des catastrophes liées à l'eau telles que les inondations et les tempêtes dans certaines régions du monde, plus des trois quarts des terres de la Terre sont devenues plus sèches de façon permanente au cours des dernières décennies, ont averti aujourd'hui les scientifiques de l'ONU dans une nouvelle analyse alarmante.
This special report on land comes at a time when the scientific evidence is unambiguous: the way we manage our land will directly determine the future of life on Earth. The planetary boundaries framework, highlighted in this report, is a critical scientific tool to understand the complex interdependencies between land, climate, biodiversity and water, among other Earth system components, offering policymakers a focused lens through which to view the potential risks and rewards of different land-use decisions.

We are used to thinking about natural disasters as events confined in time and space: the direct impact in a certain location of an earthquake happens over minutes, a hurricane over hours. While they might be confined in geography, longitudinal studies can help us understand the full range of effects and what extra efforts might be needed to rebuild.
Average global temperature in November was 1.62C above preindustrial levels, bringing average for the year to 1.60C. Data for November from the EU’s Copernicus Climate Change Service (C3S) found the average global surface temperature for the month was 1.62C above the level before the mass burning of fossil fuels drove up global heating. With data for 11 months of 2024 now available, scientists said the average for the year is expected to be 1.60C, exceeding the record set in 2023 of 1.48C.
The new study, led by researchers at the Global Systems Institute, University of Exeter, associated with the Earth Commission, and Nanjing University, assessed what this would mean for the number of people living outside the “climate niche” in which our species has thrived. It says about 60 million people are already exposed to dangerous heat (average temperature of 29°C or higher). And two billion – 22% of the projected end-of-century population – would be exposed to this at 2.7°C of global warming.
Humans prospered in a stable climate. But conditions are changing. Research out today shows 2 billion people will be pushed out of the habitable zone by 2.7C warming. Why? What does this mean for us?
Added complexity allows an economy to grow, even as resource limits are reached. But at some point, the complexity itself becomes a problem.

To tackle the challenges of competitiveness and well-being of future generations, Europe needs to accelerate the climate transition. This will require sizable investment, both public and private. National governments must thus embrace and the EU must facilitate investments in climate transition.
An MIT Energy Initiative study finds many climate-stabilization plans are based on questionable assumptions about the future cost and deployment of “direct air capture” and therefore may not bring about promised reductions.

This research reinforces the scientific consensus that the only viable strategy to limit catastrophic climate change requires drastic and immediate emissions cuts. An important study was published last month in the journal Nature, titled “Overconfidence in climate overshoot.” While increasingly dire warnings of the catastrophic impacts of global climate change continue to be published by scientists, the findings of this new paper provide another stark reminder of the urgent necessity to limit global warming by immediately reducing greenhouse gas (GHG) emissions.
A 1972 MIT study predicted that rapid economic growth would lead to societal collapse in the mid 21st century. A new paper shows we’re unfortunately right on schedule.
The idea that the AMOC is headed to collapse is very controversial, but it is clearly weakening. If the circulation did collapse, the consequences on both sides of the Atlantic Ocean would be immense—including large changes in temperature and a spike in weather-related disasters.
Disruption of the Atlantic Meridional Overturning Current could freeze Europe, scorch the tropics and increase sea level rise in the North Atlantic. The tipping point may be closer than predicted in the IPCC’s latest assessment.
Scientists may have to rethink the relationship between the ocean’s circulation and its long-term capacity to store carbon, new research from MIT suggests. As the ocean gets weaker, it could release more carbon from the deep ocean into the atmosphere — rather than less, as some have predicted.
04/17/2024 - Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.
The network of Atlantic ocean currents keeping the Earth's climate stable are far closer to collapse than first estimated, scientists warn.
The Atlantic Ocean's most vital ocean current is showing troubling signs of reaching a disastrous tipping point. Oceanographer Stefan Rahmstorf tells Live Science what the impacts could be.
The Atlantic Meridional Overturning Circulation is the main driver of northward heat transport in the Atlantic Ocean today, setting global climate patterns. Whether global warming has affected the strength of this overturning circulation over the past century is still debated: observational studies suggest that there has been persistent weakening since the mid-twentieth century, whereas climate models systematically simulate a stable circulation. Here, using Earth system and eddy-permitting coupled ocean–sea-ice models, we show that a freshening of the subarctic Atlantic Ocean and weakening of the overturning circulation increase the temperature and salinity of the South Atlantic on a decadal timescale through the propagation of Kelvin and Rossby waves. We also show that accounting for upper-end meltwater input in historical simulations significantly improves the data–model agreement on past changes in the Atlantic Meridional Overturning Circulation, yielding a slowdown of 0.46 sverdrups per decade since 1950
Global warming has already caused the Arctic to release more climate-warming methane—but exactly how much will depend closely on the actions we take to halt climate change.
Insurance costs are rising quickly across much of the country. Hurricanes are part of the reason, but it’s the other perils common across the Midwest and Great Plains that complicate costs.
Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and mainstreaming across scientific disciplines and society. The nine PBs capture the key functions regulating the Earth system. The safe operating space has been transgressed for six of these. PB science is essential to prevent further Earth system risks and has sparked new research on the precision of safe boundaries. Human development within planetary boundaries defines sustainable development, informing advances in social sciences. Each PB translates to a finite budget that the world must operate within, requiring strengthened global governance. The PB framework has been adopted by businesses and informed
The results of one election can’t stop the momentum of the energy transition. But they can do a lot of damage.

The election of Donald Trump as president for a second time and the Republican takeback of the U.S. Senate could undo many of the national climate policies that are most reducing planet-warming greenhouse gas emissions, according to climate solutions experts.When they list measures that are making the most difference, it lines up with policies Trump has said he’ll target. These rollbacks will come as more lives are being lost in heat waves, record amounts of climate pollution are accumulating in the atmosphere, the United States has been hit with what may be two of its most expensive hurricanes, and nations, which will meet in Baku, Azerbaijan next week for climate negotiations, have failed to take strong action to change these realities.
Without urgent action, Earth is heading for climate catastrophe. Yet there are reasons for hope in 2024 – including a possible peak in global greenhouse gas emissions.
The predicted El Niño is a worry, but it doesn’t guarantee the record-breaking heat we’re seeing in parts of the Northern Hemisphere.
A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California, by researchers at NIOZ and the Universities of Utrecht and Bristol. The results were published in this week’s Nature Communications. “The temperature rise we found is much larger than the 2.3 to 4.5 degrees that the UN climate panel, IPCC, has been estimating so far”, said the first author, Caitlyn Witkowski.
AMOC collapse would bring severe global climate repercussions, with Europe bearing the brunt of the consequences.

If despair is the most unforgivable sin, then hope is surely the most abused virtue. That observation feels particularly apposite as we enter the Cop season, that time of United Nations megaconferences at the end of every year, when national leaders feel obliged to convince us the future will be better, despite growing evidence to the contrary.

As climate impacts intensify globally, the Emissions Gap Report 2024: No more hot air … please! finds that nations must deliver dramatically stronger ambition and action in the next round of Nationally Determined Contributions or the Paris Agreement’s 1.5°C goal will be gone within a few years. The report is the 15th edition in a series that brings together many of the world’s top climate scientists to look at future trends in greenhouse gas emissions and provide potential solutions to the challenge of global warming.
International lawyer challenging dangerous deep water petroleum production offshore Guyana
What's the relationship between our energy consumption, our material footprint and our economies? This is the "holy trinity" as Tim Garrett and I refer to these three components in our conversation. Tim is a Professor of Atmospheric Sciences at the University of Utah, and over two years ago, he joined me to discuss the thermodynamics of collapse, where he explained his research into the behaviour of snowflakes and how you could extrapolate the behaviour of economies and civilization using the laws of thermodynamics. He's back on the show to explain how we use our energy, the necessity of a surplus of energy and how all of this relates to a society's growth and health. In this conversation we discuss questions like: Will renewables facilitate an increased consumption of fossil fuels? Can we reduce inequality by reducing energy consumption? How can we organise a wave-like civilisation, which grows and decays within safe boundaries? Can we decline in order to recover before crashing completely?
The sudden collapse of carbon sinks was not factored into climate models – and could rapidly accelerate global heating

Publié par Good Works de l’Institut Schumacher, S’effondrer ensemble: Vers l’écoliberté écrit par Jem Bendell, est désormais disponible. Yes, the French version of ‘Breaking Together’ is now available, published by Good Works, of The Schumacher Institute. Initialement sur Amazon, il sera disponible sur d’autres plateformes et dans les librairies d’ici novembre, et sera disponible en tant qu’epub gratuit au début de 2025. Je présenterai le livre fin octobre à Grenoble et/ou Genève. Initially, on Amazon, it will be available on other platforms and from book shops by November, and will be available as a free epub in early 2025. I will give a talk about it in Grenoble and/or Geneva in late October.
If modern societies are breaking down, is there a political movement ready to soften the collapse and begin anew? Or do we need new ideas and organisations for collective action? Might a local focus be the only meaningful approach as industrial consumer systems decline? Or is this a period that calls for greater international solidarity with those suffering the most? I think the conversations and initiatives in the Francophone world will provide us many insights on these questions, for a number of reasons, which I’ll come to in a moment.
Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says
We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

As a six-year investigation into the Thwaites glacier in Antarctica wraps up, the scientists involved are pessimistic for the future of this glacier and the consequences for sea level rise
Arctic Sea ice reaches it's minimum extent each year around the middle of September. This year is one of the lowest in recorded history. Ocean temperatures have been so 'off the charts' in 2023 and 2024 that scientists fear those waters have reached their capacity to mop up after us humans and are now starting to release that energy. On our current trajectory, by 2100, our planet will reach a temperature not seen for 3 MILLION years!. So...what's the plan???
Global average surface temperatures shattered all-time records in 2023 at 1.45 ± 0.12 ◦C above pre- industrial levels (WMO 2024). Worsened by climate change-induced drought, Canadian wildfires burned 18.5 million hectares, nearly three-times more land area than in any previous year on record (NRC 2023).
Literature reviews are usually quite uncontroversial. But this is not the case of “Reviewing studies of degrowth: Are claims matched by data, methods and policy analysis?”, a recent paper by Ivan Savin and Jeroen van den Bergh, two economists at the Autonomous University of Barcelona....
The EU is being sued for failing to set ambitious climate targets in sectors that contribute more than half of the bloc’s total greenhouse gas emissions.
For many of us the climate crisis mainly calls to mind rising global temperatures, but the crisis goes far beyond this – we are at risk of pushing our planet across climate ‘tipping points,’ critical thresholds where small changes can lead to abrupt and irreversible shifts in the Earth’s climate system. One major element in climate tipping is a huge system of ocean currents, the Atlantic Meridional Overturning Circulation (AMOC), which is responsible for Europe's relatively mild climate. Past climate patterns show that these currents can switch abruptly between today’s vigorous flow and a much weaker flow state. A future shutdown would have potentially devastating consequences in Europe and around the world.

SAO PAULO, Aug 1 (Reuters) - The number of fires in Brazil's Amazon rainforest region surged to a record high for the month of July in almost two decades, government data showed on Thursday, amid a drought in the region fanned by climate change. The Amazon, the world's largest rainforest, plays a vital role in curbing global warming because of the vast amounts of greenhouse gas it absorbs.
Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the first edition of a new systematic annual review.
The temperatures of the Mediterranean Sea in recent days have reached heat records set last summer, the main Spanish maritime research center told AFP Tuesday, with marine heat waves in some places exceeding 30 degrees Celsius.
An extensive new multi-proxy database of paleo-temperature time series (Temperature 12k) enables a more robust analysis of global mean surface temperature (GMST) and associated uncertainties than was previously available. We applied five different statistical methods to reconstruct the GMST of the past 12,000 years (Holocene). Each method used different approaches to averaging the globally distributed time series and to characterizing various sources of uncertainty, including proxy temperature, chronology and methodological choices. The results were aggregated to generate a multi-method ensemble of plausible GMST and latitudinal-zone temperature reconstructions with a realistic range of uncertainties. The warmest 200-year-long interval took place around 6500 years ago when GMST was 0.7 °C (0.3, 1.8) warmer than the 19th Century (median, 5th, 95th percentiles). Following the Holocene global thermal maximum, GMST cooled at an average rate −0.08 °C per 1000 years (−0.24, −0.05). The multi-method ensembles and th

The floods displaced more than 80,000 people, led to over 150,000 being injured and, on the 29th of May, to 169 fatalities with 44 people still missing (Governo do Estado de Rio Grande do Sul, 2024). Essential services were also disrupted, leaving 418,200 households without electricity and over a million consumer units without water. Dozens of municipalities lost telephone and internet services.
Greece, Italy, Spain, Portugal, France and Morocco experienced extreme heat in July 2024, causing at least 23 fatalities, widespread wildfires and bringing public life to a hold.

The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland's ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape.
Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this limit would substantially increase the probability of triggering climate tipping elements. Here, we investigate the tipping risks associated with several policy-relevant future emission scenarios, using a stylised Earth system model of four interconnected climate tipping elements.

There is increasing concern that the Atlantic Meridional Overturning Circulation (AMOC) may collapse this century with a disrupting societal impact on large parts of the world. Preliminary estimates of the probability of such an AMOC collapse have so far been based on conceptual models and statistical analyses of proxy data. Here, we provide observationally based estimates of such probabilities from reanalysis data. We first identify optimal observation regions of an AMOC collapse from a recent global climate model simulation. Salinity data near the southern boundary of the Atlantic turn out to be optimal to provide estimates of the time of the AMOC collapse in this model. Based on the reanalysis products, we next determine probability density functions of the AMOC collapse time. The collapse time is estimated between 2037-2064 (10-90% CI) with a mean of 2050 and the probability of an AMOC collapse before the year 2050 is estimated to be 59±17%.
In 2023, the CO2 growth rate was 3.37 ± 0.11 ppm at Mauna Loa, 86% above the previous year, and hitting a record high since observations began in 1958[1], while global fossil fuel CO2 emissions only increased by 0.6 ± 0.5%[2,3]....

Months of scorching temperatures sometimes over 50 degrees Celsius (122 Fahrenheit) in parts of India this year left hundreds dead or ill. Official government records put the number of heat-related deaths this year as 110, but public health experts say that number is more likely in the thousands. Poor data collection methods and reporting are stopping the country from getting a more accurate picture of how deadly the heat is. Experts are concerned that it's hindering efforts to better prepare for future heat waves.

The 12 months from July 2023 to June 2024 are shown with a thick red line, while all other 12-month periods are shown with thin lines shaded according to the decade, from blue (1940s) to brick red (2020s).
Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

New research shows the company’s scientists were as “skillful” as independent experts in predicting how the burning of fossil fuels would warm the planet and bring about climate change.
Resilience here, then, is not the naïve faith in riding the storm and putting the world back together more or less as it was, issue by issue, but recognising the necessity to fundamentally reorganise and reorient human society in ways that can allow human flourishing and ecological sustainability in symbiotic and mutually supportive relations of reciprocity and regeneration - and in a multiplicity of ways.

Mainstream media are ignoring a scientist who is whistleblowing the climate profession. During the five years since new kinds of activism brought the climate issue into the headlines like never before, the topic has more clearly become one where people respond due to their preexisting worldviews. It’s not just believers and sceptics, but there are those who think technology can save us, those who think it’s too late; those who think the science is clear, others who think it is open; those who believe humans will muddle through and those predicting human extinction. Climate scientists themselves now range from those emphasizing ‘we can do this’ to those that express their grief and outrage by gluing themselves to buildings. Meanwhile, misleading narratives are amplified by a variety of vested interests, including fossil fuels, nuclear, and clean tech. Climatologist Dr Wolfgang Knorr is an unusual voice in this cacophony because he has been ‘blowing the whistle’ on the climate science itself and how it is being

Carbon Brief provides an updated analysis of when the world will likely exceed the Paris 1.5C limit
Summary for Policymakers. A Report of the Intergovernmental Panel on Climate Change
Historical responsibility for climate change is radically shifted when colonial rule is taken into account, Carbon Brief analysis reveals.
Since the Paris Agreement in 2016, the world’s 60 largest private banks financed fossil fuels with USD $6.9 trillion. Nearly half – $3.3 trillion – went towards fossil fuel expansion. In 2023, banks financed $705 billion in fossil fuel financing with $347 billion going to fossil fuel expansion alone.
Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC). Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activit
Natural ecosystems store large amounts of carbon globally, as organisms absorb carbon from the atmosphere to build large, long-lasting, or slow-decaying structures such as tree bark or root systems. An ecosystem’s carbon sequestration potential is tightly linked to its biological diversity. Yet when considering future projections, many carbon sequestration models fail to account for the role biodiversity plays in carbon storage. Here, we assess the consequences of plant biodiversity loss for carbon storage under multiple climate and land-use change scenarios. We link a macroecological model projecting changes in vascular plant richness under different scenarios with empirical data on relationships between biodiversity and biomass. We find that biodiversity declines from climate and land use change could lead to a global loss of between 7.44-103.14 PgC (global sustainability scenario) and 10.87-145.95 PgC (fossil-fueled development scenario). This indicates a self-reinforcing feedback loop, where higher levels
With current policies the Earth is on track to a warming of around 3 °C above preindustrial temperatures, a level of heat our planet has not seen for millions of years. Ecosystems, human society and infrastructure are not adapted to these temperatures. Due to non-linear effects, the impacts will be much more severe than just three times as bad as after 1 °C of warming. Land areas will continue to warm much more than the global average, many regions twice as much or even more. Extreme heat will become far more frequent and a major cause of human mortality, making large parts of the tropical land area essentially too hot to live. In addition, extreme rainfall and flooding, droughts, wildfires and harvest failures will increase in frequency and severity. The destructive power of tropical cyclones will also increase. Sea-level rise will accelerate further, and the destabilization of ice sheets will commit our descendants to loss of coastal cities and island nations. The risk of crossing devastating and irreversib

Climate scientist Kevin Anderson is one of the world's leading authorities on carbon budgets. He told DW keeping global warming below 2 degrees is a choice — but it's one we have to make it fast.
The new report evokes a mild sense of urgency, calling on governments to mobilise finance to accelerate the uptake of green technology. But its conclusions are far removed from a direct interpretation of the IPCC’s own carbon budgets (the total amount of CO₂ scientists estimate can be put into the atmosphere for a given temperature rise).

Le sepsis est une affection potentiellement mortelle qui survient lorsque le système immunitaire réagit de façon extrême à une infection, entraînant une dysfonction d’organe (4). Cette réaction immunitaire provoque des lésions tissulaires et organiques et peut entraîner un état de choc, une défaillance multiviscérale et parfois le décès, surtout si elle n’est pas détectée tôt et traitée rapidement. Le sepsis peut toucher n’importe qui, mais les personnes âgées, les jeunes, les femmes enceintes ou les personnes souffrant d’autres problèmes de santé sont exposées à un risque plus élevé.
Insight and inspiration in turbulent times. People have widely varying beliefs about climate change. A surprising number still think that it’s a hoax, or that it’s a trivial problem. At the other end of the opinion spectrum, some say it signals the end of the world and there’s nothing we can do to stop it. Between those extremes are lots of folks who believe climate change is a serious dilemma, but we can deal with it by installing solar panels, nuclear power, solar radiation management technologies, and/or machines to remove carbon dioxide (CO2) from the atmosphere, after which we will continue to live mostly the way we do today.
This essay takes up and extends an analysis of the ambitions of the energy transition presented during the conference entitled “L’erreur fondamentale de la transition”, held in Lausanne in December 2022, at the annual Switzerland ShiftersDay. The intervention questioned the conceptualization of energy transition, given possible inaccuracies, or errors in the categorization of reality. It is not certain that the energy contained in the wind, solar radiation, or atoms is equivalent to hydrocarbon energy for human societalneeds. Although all energies are theoretically convertible into one another, the assumption that any type of energy can always be replaced by another is likely to prove false. An energy transition based on the substitution of energies would then be inconceivable.
Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN), is the first book to document the development and nature of climate obstruction activities across Europe, which are efforts to deliberately slow or block climate action.

As the public conversation on climate change evolves, so too does the sophistication and range of arguments used to downplay or discount the need for action (McKie, Reference McKie2019; Norgaard, Reference Norgaard2011). A mainstay of this counter-movement has been outright denial of the reality or human causation of climate change (Farrell et al., Reference Farrell, McConnell and Brulle2019), supplemented by climate-impact scepticism (Harvey et al., Reference Harvey, Van Den Berg, Ellers, Kampen, Crowther, Roessingh and Mann2018) and ad hominem attacks on scientists and the scientific consensus (Oreskes & Conway, Reference Oreskes and Conway2011). A fourth strategy has received relatively little attention to date: policy-focused discourses that exploit contemporary discussions on what action should be taken, how fast, who bears responsibility and where costs and benefits should be allocated (Bohr, Reference Bohr2016; Jacques & Knox, Reference Jacques and Knox2016; McKie, Reference McKie2019). We call these ‘
Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN) and published via Oxford University Press, reveals extensive networks impeding climate action within the region and surrounding states. In Italy and Germany, far-right networks spread misinformation by questioning climate science’s validity, while in Spain and the UK, blame-shifting and deflecting responsibility for climate action are common. European-based fossil fuel industries, like Shell, engage in greenwashing, by framing gas as a ‘bridging technology crucial for the energy transition’, delaying genuine progress.

Cultured meat is an emerging biotechnology that aims to produce meat from animal cell culture, rather than from the raising and slaughtering of livestock, on environmental and animal welfare grounds. The detailed understanding and accurate manipulation of cell biology are critical to the design of cultured meat bioprocesses. Recent years have seen significant interest in this field, with numerous scientific and commercial breakthroughs. Nevertheless, these technologies remain at a nascent stage, and myriad challenges remain, spanning the entire bioprocess. From a cell biological perspective, these include the identification of suitable starting cell types, tuning of proliferation and differentiation conditions, and optimization of cell–biomaterial interactions to create nutritious, enticing foods. Here, we discuss the key advances and outstanding challenges in cultured meat, with a particular focus on cell biology, and argue that solving the remaining bottlenecks in a cost-effective, scalable fashion will req

The modern agricultural production system relies heavily on the use of synthetic pesticides, but over the course of recent decades various concerns have been raised on the associated negative externalities touching a variety of dimensions, such as human health and the environment. Yet, the magnitude of those effects is still unclear and data availability is scattered and heterogenous across dimensions, regions, and time. The public sector is called upon to develop and implement strategies to face those externalities and their associated social costs. This study aims to provide an assessment of social costs of pesticides in France in the prospect of an integration to the public budget spending, helping public authorities to identify financial flows of public funding with an impact perspective, within a methodological framework based on the social norms at the core of the public system. The results show that the social costs attributable to synthetic pesticide use in France amounted to 372 million euros, of whi
Global temperature (12-month mean) is still rising at 1.56°C relative to 1880-1920 in the GISS analysis through April (Fig. 1). [Robert Rohde reports that it is 1.65°C relative to 1850-1900 in the BerkeleyEarth analysis.[3]] Global temperature is likely to continue to rise a bit for at least a month, peak this summer, and then decline as the El Nino fades toward La Nina. Acceleration of global warming is now hard to deny. The GISS 12-month temperature is now 0.36°C above the 0.18°C/decade trend line, which is 3.6 times the standard deviation (0.1°C). Confidence in global warming acceleration thus exceeds 99%, but we need to see how far temperature falls with the next La Nina before evaluating the post-2010 global warming rate.

Record-breaking temperatures were recorded across the globe in 2023. Without climate action, adverse climate-related health impacts are expected to worsen worldwide, affecting billions of people. Temperatures in Europe are warming at twice the rate of the global average, threatening the health of populations across the continent and leading to unnecessary loss of life. The Lancet Countdown in Europe was established in 2021, to assess the health profile of climate change aiming to stimulate European social and political will to implement rapid health-responsive climate mitigation and adaptation actions. In 2022, the collaboration published its indicator report, tracking progress on health and climate change via 33 indicators and across five domains.
Climate scientists have told the Guardian they expect catastrophic levels of global heating. Here’s what that would mean for the planet
Exclusive: Planet is headed for at least 2.5C of heating with disastrous results for humanity, poll of hundreds of scientists finds
Here, we show that the Last Glacial Maximum (LGM) provides a stronger constraint on equilibrium climate sensitivity (ECS), the global warming from increasing greenhouse gases, after accounting for temperature patterns. Feedbacks governing ECS depend on spatial patterns of surface temperature (“pattern effects”); hence, using the LGM to constrain future warming requires quantifying how temperature patterns produce different feedbacks during LGM cooling versus modern-day warming. Combining data assimilation reconstructions with atmospheric models, we show that the climate is more sensitive to LGM forcing because ice sheets amplify extratropical cooling where feedbacks are destabilizing. Accounting for LGM pattern effects yields a median modern-day ECS of 2.4°C, 66% range 1.7° to 3.5°C (1.4° to 5.0°C, 5 to 95%), from LGM evidence alone. Combining the LGM with other lines of evidence, the best estimate becomes 2.9°C, 66% range 2.4° to 3.5°C (2.1° to 4.1°C, 5 to 95%), substantially narrowing uncertainty compared t

Jumping into the future head first, blindfolded, handcuffed, and in darkness
Mitigating climate change necessitates global cooperation, yet global data on individuals’ willingness to act remain scarce. In this study, we conducted a representative survey across 125 countries, interviewing nearly 130,000 individuals. Our findings reveal widespread support for climate action. Notably, 69% of the global population expresses a willingness to contribute 1% of their personal income, 86% endorse pro-climate social norms and 89% demand intensified political action. Countries facing heightened vulnerability to climate change show a particularly high willingness to contribute. Despite these encouraging statistics, we document that the world is in a state of pluralistic ignorance, wherein individuals around the globe systematically underestimate the willingness of their fellow citizens to act. This perception gap, combined with individuals showing conditionally cooperative behaviour, poses challenges to further climate action. Therefore, raising awareness about the broad global support for climat

Over the past 50 years, humans have extracted the Earth’s groundwater stocks at a steep rate, largely to fuel global agro-economic development. Given society’s growing reliance on groundwater, we explore ‘peak water limits’ to investigate whether, when and where humanity might reach peak groundwater extraction. Using an integrated global model of the coupled human–Earth system, we simulate groundwater withdrawals across 235 water basins under 900 future scenarios of global change over the twenty-first century. Here we find that global non-renewable groundwater withdrawals exhibit a distinct peak-and-decline signature, comparable to historical observations of other depletable resources (for example, minerals), in nearly all (98%) scenarios, peaking on average at 625 km3 yr−1 around mid-century, followed by a decline through 2100. The peak and decline occur in about one-third (82) of basins, including 21 that may have already peaked, exposing about half (44%) of the global population to groundwater stress. Most
Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies. Rivers provide a m
Decarbonization efforts and sustainability transformations represent highly contested socio-political projects. Yet, they often encounter various forms of depoliticization. This article illuminates how a grand socio-ecological challenge like the energy transition gets depoliticized by an unusual suspect, namely Germany's Green Party. Based on a qualitative content analysis of Green Party programs, party conventions, and additional documents published between 1980 and 2021, this article traces how the Green Party has depoliticized the energy transition over time, emphasizing a shift from radical societal change to ecological modernization. The changing stance of the German Greens on the country's energy transition reflects more profound changes of a future society the party collectively envisions through their energy and climate change agenda. These changes result from a struggle between moderates advocating incremental political reforms and radicals aiming for more fundamental and systemic societal change.
Cost of environmental damage will be six times higher than price of limiting global heating to 2C, study finds
Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average tempe

This means that in 2031, it’ll cost more energy to extract the fossil fuels than we would gain by using them, rendering extraction unfeasibly expensive. Yet, rather than use our remaining years of access to these fuels to turbo-charge new energy infrastructure, fossil fuels are being extracted and burned for business as usual: quick cash. Around the world, the lights will go off in nations that don’t have back-up renewables. That’s most of them.
Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.
A long-term sea level dataset shows ocean surface heights continuing to rise at faster and faster rates over decades of observations. Global average sea level rose by about 0.3 inches (0.76 centimeters) from 2022 to 2023, a relatively large jump due mostly to a warming climate and the development of a strong El Niño. The total rise is equivalent to draining a quarter of Lake Superior into the ocean over the course of a year.
Weak government climate policies violate fundamental human rights, the European court of human rights has ruled
If the anomaly does not stabilise by August, ‘the world will be in uncharted territory’, says climate expert
Carbon Brief explores which countries are or have targets to be net-negative, and the moral and scientific arguments for such a milestone.
The rapid growth of clean energy technologies is driving a rising demand for critical minerals. In 2022 at the 15th Conference of the Parties to the Convention on Biological Diversity (COP15), seven major economies formed an alliance to enhance the sustainability of mining these essential decarbonization minerals. However, there is a scarcity of studies assessing the threat of mining to global biodiversity. By integrating a global mining dataset with great ape density distribution, we estimated the number of African great apes that spatially coincided with industrial mining projects. We show that up to one-third of Africa’s great ape population faces mining-related risks. In West Africa in particular, numerous mining areas overlap with fragmented ape habitats, often in high-density ape regions. For 97% of mining areas, no ape survey data are available, underscoring the importance of increased accessibility to environmental data within the mining sector to facilitate research into the complex interactions betw
New research suggests 75% of the rainforest has become less resilient to stress since the early 2000s.
A recent paper suggested damaging climate tipping points could be closer than first thought.
Humanity at risk if we keep thinking everything is under control
We ran computer programs that simulate ecosystems 70,000 times and the results are very worrying.
