A recent UK national security assessment on biodiversity and ecosystem collapse made headlines, not for its dire warnings, but for its omissions. It's part of a larger trend of governments keeping climate security reports from the public.

Even as weather extremes worsen, the voices calling for the rolling back of environmental rules have grown louder and more influential

Science-based policies could successfully limit human-caused climate change, but when political parties are allowed to accept money from special interests, policies are distorted to the point of being ineffective. This is a solvable problem, but to clarify the situation and the needed actions, we need to first marshal the evidence. The draft Prologue of Sophie’s Planet is intended to help coherently organize the evidence. Here is Part III of V, with the final two paragraphs of Part II.

Welcome to the Global Climate Highlights 2025 report, compiled by the Copernicus Climate Change Service (C3S). The Global Climate Highlights 2025 report provides authoritative climate data and concise insight on a global scale about 2025's climate conditions, covering surface and sea surface temperature, heat stress, sea ice extent in the Arctic and Antarctic, among others.

Three major Defence Agencies are quietly admitting what most still refuse to face: climate breakdown is coming for our food, and the cracks are already spreading. While the wealthy cling to logistics and illusion, the real defence strategy is soil and local growers who refuse to let their communities starve.

A critical step on the path towards climate neutrality, the European Union’s 2040 target calls for a 90-per-cent reduction in emissions. Yet as far-reaching as this goal may seem, its provisions constitute a weakening of Europe’s climate ambitions under the Green Deal. By allowing costly and ineffective CO2 removal and storage technologies as a way of lowering emissions, the target risks deterring direct emission cuts and outsourcing pollution.

US President Donald Trump has announced the reversal of the so-called endangerment finding, a key Obama-era scientific ruling that underpins much of US environmental legislation. As a result of this, experts are predicting various environmental and economic impacts, though the decision by the US Environmental Protection Agency (EPA) is expected to be challenged in the courts from environmental groups.

Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world

Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware

Today, we are close to the critical moment when conventional economic growth becomes impossible on a finite planet, constrained by two parallel factors: resource depletion and pollution. Tthe depletion of fossil fuels and other mineral commodities is placing heavy constraints on both industrial and agricultural production. We are not running out of anything yet, but the cost of extraction is increasing, just as the damage that extraction causes to the ecosystem. On the other side, pollution is appearing in more than one form. Chemical pollution is growing in terms of heavy metals, endocrine-disruptors, and other poisoning substances, while climate change can be seen as another form of pollution generated by the excess of CO2 in the atmosphere.

In Belem, Brazil’s leader, President Lula da Silva, opened the talks by denouncing obstructionists who “reject scientific evidence and attack institutions.” “They manipulate algorithms, sow hatred and spread fear,” he said, describing a surge in disinformation and propaganda aimed at blocking action to slow climate change. The summit, for the first time, put the issue on the agenda. A coalition of countries and international agencies issued a separate “Declaration on Information Integrity on Climate Change,” calling on governments to address climate disinformation, promote transparency and protect journalists, scientists and environmentalists.

By the end of this century, parts of Africa could face heatwaves for 250-300 days a year, which will make it difficult for people to survive.

Climate change is making it challenging to identify future host cities.

The world seems headed into another El Nino, just 3 years after the last one. Such quick return normally would imply, at most, an El Nino of moderate strength, but we suggest that even a moderately strong El Nino may yield record global temperature already in 2026 and still greater temperature in 2027. The extreme warming will be a result mainly of high climate sensitivity and a recent increase of the net global climate forcing, not the result of an exceptional El Nino, per se. We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury.

Climate change could lead to half a million more deaths from malaria in Africa over the next 25 years, according to new research.

With warming set to pass the critical 1.5-degree limit, scientists are warning that the world is on course to trigger tipping points that would lead to cascading consequences — from the melting of ice sheets to the death of the Amazon rainforest — that could not be reversed.

The world endured its costliest wildfire on record in 2025, its sixth-deadliest heat wave, and four floods or storms that caused at least 1,000 deaths.

Children’s developing lungs make them vulnerable to air pollution.

As climate and geopolitics shocks bite, countries are rebuilding food buffers. The UK clings to neoliberal ideas while households pay the price

Melting glaciers, coastal areas wiped off the map and regular 40C heat in Europe. Climate experts warn the gloomy predictions of long term environmental change are no longer the future - they are already here. Last year was the third hottest on record, with the World Meteorological Organization this week warning that 2025 continued a run of “extraordinary” global temperatures. The EU has said the Paris climate agreement of 1.5C could be broken before 2030, a decade sooner than expected.

The world's oceans absorbed a record amount of heat in 2025, an international team of scientists said Friday, further priming conditions for sea level rise, violent storms, and coral death.

Legal action has brought important decisions, from the scrapping of fossil fuel plants to revised climate plans

The datasets used to diagnose the modern history of the planet’s climate — and to proclaim that the world is now very near to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming — typically begin with the year 1850. The new one goes all the way back to 1781. This extended time frame matters because greenhouse gases in the atmosphere increased 2.5 percent between 1750 and 1850, enough to have caused some warming that the data hasn’t accounted for.

The activist and author of Here Comes the Sun discusses rapid advances in solar and wind power and how the US ceded leadership in the sector to its main rival

From floods to droughts, erratic weather patterns are affecting food security, with crop yields projected to fall if changes are not made

Since 2010, the Environmental Protection Agency (EPA) has required large industrial facilities to report their greenhouse gas emissions. The data, which the EPA’s Greenhouse Gas Reporting Program has been collecting since 2011, is essential in efforts to reduce emissions and provides vital information to the public about climate pollution from the largest U.S. polluters. However, the Trump EPA has proposed to put an end to greenhouse gas reporting by major polluters. This move is consistent with the Trump administration’s intent to make climate denial an official U.S. policy and restricts the public from the right to know. Subsequently, it will deprive communities from having access to a critical tool for holding pollutants accountable.

Real skeptics study the evidence and ask questions, rather than taking political dogma on faith. Experiencing disasters can open more eyes to the risks.

Rob Hopkins has spent the past decades exploring one question: what if we could fall in love with the future? As co-founder of Transition Network and Transition Town Totnes, and author of four books, he travels the world helping communities cultivate imagination, longing and possibility. He believes that the transition we so urgently need depends on one thing above all: imagination.

UN GEO report says ending this harm key to global transformation required ‘before collapse becomes inevitable’

Exclusive: UCL scientists find large swathes of southern Europe are drying up, with ‘far-reaching’ implications

I always say that models are not predictions; they are qualitative illustrations of what the future could be. But as the future gets closer to the present, models can start being seen as predictive tools. It is the weather/climate dichotomy, so aptly exploited to confuse matters by politically minded people in the discussion about climate. Right now, we are getting close to the point that we could forecast a collapse in the same way as we can forecast the trajectory of a tropical storm. So, you remember how “The Limits to Growth” generated a long term forecast in 1972. Here it is

Budgets are now climate policy. But mainstream media hasn’t caught up.

Rain-fed agriculture, the backbone of rural livelihoods, are no longer predictable as droughts follows floods.

The growth rate of greenhouse gas (GHG) climate forcing increased rapidly in the last 15 years to about 0.5 W/m2 per decade, as shown by the “colorful chart” for GHG climate forcing that we have been publishing for 25 years (Fig. 1).[1] The chart is not in IPCC reports, perhaps because it reveals inconvenient facts. Although growth of GHG climate forcing declined rapidly after the 1987 Montreal Protocol, other opportunities to decrease climate forcing were missed. If policymakers do not appreciate the significance of present data on changing climate forcings, we scientists must share the blame.

The UK has announced much harsher rules for asylum seekers including the prospect of more deportations for those whose applications fail. The US is trebling the size of its deportation force. The EU is doubling its border budgets. And in the coming decades, hundreds of millions of people might be displaced by ecological changes.

Gates recently called for a ‘strategic pivot’ in climate strategy. That appears to have hit a nerve.

We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth.

22 of the planet’s 34 vital signs are at record levels, with many of them continuing to trend sharply in the wrong direction. This is the message of the sixth issue of the annual “State of the climate” report. The report was prepared by an international coalition with contribution from the Potsdam Institute for Climate Impact Research (PIK) and led by Oregon State University scientists. Published today in BioScience, it cites global data from the Intergovernmental Panel on Climate Change (IPCC) in proposing “high-impact” strategies.

Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30

The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.

James Hansen - Climate Reckoning in ATLAS25, Operaatio Arktis, Helsinki, Finland

We already have plenty of evidence of what happens when things better left to governments — which in this case might decide to never flip the switch at all — are ceded to private industry.

A “pushing and triggering” mechanism has has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across the atmosphere, ocean and cryosphere this century.

Ahead of the United Nations climate talks in Brazil, advocacy groups are pushing for companies and governments to set meaningful emissions targets to lower emissions from livestock.

Five of the seven breached planetary boundaries are linked to food systems. By transforming production and adopting a “planetary health diet,” we can halve food-related climate emissions and prevent millions of deaths, according to the 2025 EAT-Lancet Commission.

A climate-focused report out of Europe throws serious shade at plug-in hybrid electric (PHEV) cars, pointing out that they emit nearly as much carbon dioxide emissions as combustion engine-powered vehicles. In fact, it highlights how real-world emissions from supposedly greener PHEVs has increased over the years above officially recorded figures to nearly five times. Yikes! The findings come from the European Federation for Transport and Environment (T&E), a clutch of non-government organizations focused on sustainable transport policy across the continent. The report has been published ahead of a review of automotive CO2 emission standards, which would see Europe continue to sell plug-in hybrid electric vehicles beyond 2035, when they're set to be phased out in order to meet EU climate targets.

It looked like snow under water: white, endless, and still. The reef, my friend Lisbeth said, was “the most beautiful thing she’d ever seen.” For a second, I almost agreed. Then, I stared at it for a long time before replying. She wasn’t wrong about its beauty. But she was also showing me death. Bleached coral isn’t a kind of coral. It’s the moment just after the funeral, what’s left when life is gone. A cathedral of bone-white skeletons stretching over an empire of calcified death. From above, it glows like marble. Up close, it’s a graveyard.

Researchers have discovered dozens of new methane seeps littering the ocean floor in the Ross Sea coastal region of Antarctica, raising concerns of an unknown positive climate feedback loop that could accelerate global warming.

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

Four key parts of the Earth’s climate system are destabilising, according to a new study with contributions from the Potsdam Institute for Climate Impact Research (PIK). Researchers analysed the interconnections of four major tipping elements: the Greenland ice sheet, the Atlantic meridional overturning circulation (AMOC), the Amazon rainforest and the South American monsoon system. All four show signs of diminished resilience, raising the risk of abrupt and potentially irreversible changes.

EU officials warn climate breakdown and wildlife loss ‘are ruining ecosystems that underpin the economy’ […] The European way of life is being jeopardised by environmental degradation, a report has found, with EU officials warning against weakening green rules. The continent has made “important progress” in cutting planet-heating pollution, according to the European Environment Agency, but the death of wildlife and breakdown of the climate are ruining ecosystems that underpin the economy.

The main report provides an integrated narrative, examining the central and vital role that the climate and natural environment play in ensuring health, resilience and prosperity for people, anchored in the EU’s vision for a sustainable Europe by 2050.

Why Environmental Writing Isn’t Resonating As Much Anymore Active hope, not optimism. And why facts alone no longer move people. Environmental pieces aren’t landing like they used to. Writers, researchers, and activists are noticing the shift: climate content that once sparked engagement now fades into the background. The question isn’t whether people care about the planet — it’s that many readers are moving past narratives of awareness and individual action (or at least I think they should!). They want to understand power. They want to understand systems. They want hope rooted in collective transformation, not optimism sold as personal therapy. We Know the Planet Is Dying. So Now What?

Predictably, soon, most young people will reject extremist views. This will be none too soon because it is the essential step leading to global political leadership that appreciates the threat posed by climate’s delayed response to human-made changes of Earth’s atmosphere. Then the annual fraud of goals for future “net zero” emissions announced at United Nations COP (Conference of Parties) meetings might be replaced by realistic climate policies. It is important, by that time, that we have better knowledge of the degree and rate at which human-made forcing of the climate system must be decreased to avoid irreversible, unacceptable consequences.

How does one talk about climate change when armed conflicts are spiralling out of control?

Conservative leader Kemi Badenoch has described her plan to “maximise extraction” of the UK’s oil and gas from the North Sea as a “common sense” energy policy. Politicians are using language like this increasingly often – calling themselves “pragmatic” on climate change and invoking “common sense”. It sounds reasonable, reassuring, and grownup – the opposite of “hysterical” campaigners or “unrealistic” targets.

Earth’s average temperature rose more than 1.5°C above pre-industrial levels in 2024 for the first time – a critical threshold in the climate crisis. At the same time, major armed conflicts continue to rage in Ukraine, Gaza, Sudan and elsewhere. What should be increasingly clear is that war now needs to be understood as unfolding in the shadow of climate breakdown. The relationship between war and climate change is complex. But here are three reasons why the climate crisis must reshape how we think about war.

Avant l’été, un site gouvernemental américain d’information sur le climat a été invisibilisé par l’administration Trump. Depuis, d’anciens employés fédéraux travaillent bénévolement pour ressusciter son contenu.

Climate.gov, which went dark this summer, to be revived by volunteers as climate.us with expanded missionEarlier this summer, access to climate.gov – one of the most widely used portals of climate information on the internet – was thwarted by the Trump administration, and its production team was fired in the process.

The Atlantic meridional overturning circulation (AMOC) is an important tipping element in the climate system. There is a large uncertainty whether the AMOC will start to collapse during the century under future climate change, as this requires long climate model simulations which are not always available. Here, we analyze targeted climate model simulations done with the Community Earth System Model (CESM) with the aim to develop a physics-based indicator for the onset of an AMOC tipping event. This indicator is diagnosed from the surface buoyancy fluxes over the North Atlantic Ocean and is performing successfully under quasi-equilibrium freshwater forcing, freshwater pulse forcing, climate change scenarios, and for different climate models. An analysis consisting of 25 different climate models shows that the AMOC could begin to collapse by 2063 (from 2026 to 2095, to percentiles) under an intermediate emission scenario (SSP2-4.5), or by 2055 (from 2023 to 2076, to percentiles) under a high-end emission scenar

This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC's Working Group III. This bias stems from structural features of the scientific field that prioritizes innovation, leading to the overrepresentation of technological solutions in climate research. Funding mechanisms further reinforce this tendency by incentivizing collaboration with industrial R&D, creating a self-reinforcing loop in which scientific authority and industrial interests converge. The IPCC's institutional positioning—as a policy-relevant yet politically cautious body—amplifies this dynamic by favoring allegedly “cost-effective” technological pathways that lack practical feasibility.

Our modelling of European fish species shows a patchwork of winners and losers as sea temperatures rise.

A team of researchers in California drew notoriety last year with an aborted experiment on a retired aircraft carrier that sought to test a machine for creating clouds.   But behind the scenes, they were planning a much larger and potentially riskier study of salt-water-spraying equipment that could eventually be used to dim the sun’s rays — a multimillion-dollar project aimed at producing clouds over a stretch of ocean larger than Puerto Rico.

Passing 1.5ºC is now inevitable. Overshoot scenarios tell us that we can relatively safely pass this level but then bring temperatures back down again, but how realistic are they, and how safe?

Climate sensitivity is substantially higher than IPCC’s best estimate (3°C for doubled CO2), a conclusion we reach with greater than 99 percent confidence. We also show that global climate forcing by aerosols became stronger (increasingly negative) during 1970-2005, unlike IPCC’s best estimate of aerosol forcing. High confidence in these conclusions is based on a broad analysis approach. IPCC’s underestimates of climate sensitivity and aerosol cooling follow from their disproportionate emphasis on global climate modeling, an approach that will not yield timely, reliable, policy advice.

The White House has instructed NASA employees to terminate two major, climate change-focused satellite missions. As NPR reports, Trump officials reached out to the space agency to draw up plans for terminating the two missions, called the Orbiting Carbon Observatories. They've been collecting widely-used data, providing both oil and gas companies and farmers with detailed information about the distribution of carbon dioxide and how it can affect crop health.

The report, which is being used to justify the rollback of a huge number of climate regulations, is full of misinformation—with many claims based on long-debunked research.

Exclusive: Increasingly extreme weather a threat to production and supply chains in Britain and elsewhere

Bad climate news is everywhere. Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods. We are living in a world that is warming at the fastest rate since records began. Yet, governments have been slow to act.

Healthy environment a human right, UN court says in landmark climate ruling

António Guterres says ‘sun is rising on a clean energy age’ as 90% of renewable power projects cheaper than fossil fuels

2024 was the hottest year on record [1], with global temperatures exceeding 1.5 °C above preindustrial climate conditions for the first time and records broken across large parts of Earth’s surface. Among the widespread impacts of exceptional heat, rising food prices are beginning to play a prominent role in public perception, now the second most frequently cited impact of climate change experienced globally, following only extreme heat itself [2]. Recent econometric analysis confirms that abnormally high temperatures directly cause higher food prices, as impacts on agricultural production [3] translate into supply shortages and food price inflation [4, 5]. These analyses track changes in overall price aggregates which are typically slow-moving, but specific food goods can also experience much stronger short-term price spikes in response to extreme heat.

Planet Earth is living on borrowed time, a new global report reveals. The world must stop burning fossil fuels now and take urgent steps to reduce global warming.

The constant deluge of bad news about rising global temperatures and their impacts can make it feel like the world is ending. Is it?

C’est une tendance qui ne faiblit pas sur les réseaux sociaux. Face à la crise écologique, des centaines de jeunes témoignent de leur pessimisme quant à notre capacité à redresser la barre : on les appelle les "climate doomers". Résultat d’une éco-anxiété grandissante, ce phénomène participe à freiner l’action climatique.

in January, a group of present and former Republican state officials gathered at a posh resort in Sea Island, Georgia, together with conservative leaders, for a two-day lesson in how to dismantle corporate America’s most ambitious response to climate change. At the Cloister, with its golf courses, tennis courts, and beaches, ESG was denounced as a sinister force undermining free markets and democracy.

Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say

For decades, the surface of the polar Southern Ocean (south of 50°S) has been freshening—an expected response to a warming climate. This freshening enhanced upper-ocean stratification, reducing the upward transport of subsurface heat and possibly contributing to sea ice expansion. It also limited the formation of open-ocean polynyas. Using satellite observations, we reveal a marked increase in surface salinity across the circumpolar Southern Ocean since 2015. This shift has weakened upper-ocean stratification, coinciding with a dramatic decline in Antarctic sea ice coverage. Additionally, rising salinity facilitated the reemergence of the Maud Rise polynya in the Weddell Sea, a phenomenon last observed in the mid-1970s.

Research in Chile suggests climate crisis makes eruptions more likely and explosive, and warns of Antarctica risk

“We have failed to shift the narrative and we are still caught up in the same legal, economic and political systems,” said David Suzuki in an exclusive interview with iPolitics. “For me, what we’ve got to do now is hunker down.”

Satellite data processing algorithms developed by ICM-CSIC have played a crucial role in detecting this significant shift in the Southern Hemisphere, which could accelerate the effects of climate change.

The world has been too optimistic about the risk to humanity and planet – but devastation can still be avoided, says Timothy Lenton

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

Between 80% and 89% of the world’s people want their governments to do more about climate change. This fact is the central tenet of the 89% Project for climate journalism. Timed to coincide with Earth Day and Earth Week, the project launched in April, 2025, and will culminate in another week of focused stories in October, just before the next COP meeting in Brazil.

Stefan Rahmstorf, Professor of Physics os the Ocean at the University of Potsdam since 2000, presents a colloquium on the risks associated with the destabilization of the Atlantic Meridional Overturning Circulation (AMOC) and its potential consequences for the global climate.

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. Below we explain what the Court decided, why it matters, and what it might mean in a New Zealand context with Smith v Fonterra still moving through the courts.

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

Heat waves are getting more dangerous with climate change — and we may still be underestimating them

Climate misinformation campaigns have shifted tactics, a comprehensive new analysis shows.

Back in 2018, Yale economist William Nordhaus won the Nobel Prize for his work on his Dynamic Integrated Climate-Economy (DICE) model. The idea was to set up a picture of the global economy, add on some estimates of the economic costs of warming with a “damage function,” plus estimates of what climate policy would cost, and all adjusted with a discount term to account for how people value current production more than future production (according to economists, at least). That way you can calculate an “optimal” climate policy in the form of a carbon tax that would precisely compensate for warming damages without burdening the economy too much.

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.

False claims obstructing climate action, say researchers, amid calls for climate lies to be criminalised

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.

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

Even if agricultural practices adapt in response to higher temperatures, five of the world's six main staple crops will suffer severe losses due to climate change. Global corn yields are projected to fall by about 12 or 28 per cent by the end of the century

Les financements aux industries du pétrole et du gaz repartent de plus belle. Le rapport Banking on climate chaos, signé par huit ONG, estime à près de 900 milliards de dollars les financements octroyés en 2024 par 65 banques aux industriels du secteur, en augmentation de 23%. Le backlash contre la finance durable n’est pas étranger à ce nouvel appétit de la finance pour les hydrocarbures.

I am writing this message to the millions of people who have been involved in the climate movement over the past several years. This movement has been an incredible force, thanks to your courage, passion and commitment. It has created a new public consciousness and a powerful sense of popular will. These are major achievements. And yet it is clear that we have now reached an impasse and a new path is needed.

Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?

– how climate scientists and the IPCC still won’t tell the truth about accelerating climate change.

Exclusive: Climate.gov, which supports public education on climate science, will soon no longer publish new contentA major US government website supporting public education on climate science looks likely to be shuttered after almost all of its staff were fired, the Guardian has learned.

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

"What we are seeing is compelling evidence that the climate crisis is not just an environmental emergency, it is potentially a neurological one."

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.

There’s frustration among researchers that falling pH levels in seas around the globe are not being taken seriously enough, and that until the buildup of CO2 is addressed, the consequences for marine life will be devastating

A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

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.

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.

Despite mounting evidence of global warming’s costs, the Trump administration has made multiple moves to avoid tracking climate-related economics.

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate

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.

On 21 April 2019, I was on Waterloo Bridge in London with my younger siblings. Around us were planters full of flowers where there were once cars, and people singing. This was the spring iteration of Extinction Rebellion, when four bridges in London were held by protesters. My siblings, then 14, had been going out on school strike inspired by Greta Thunberg, and wanted to see her speak.

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.

A new report draws on internal company documents and other public records to comprehensively outline the fossil fuel industry’s decades-long campaign to mislead the public and avoid paying for their products’ harms.

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.

In the run-up to the November election, conventional analysis suggested that a Trump victory would mean an additional four billion tons of CO2 emissions to the atmosphere by 2030, a total surrender on the climate pledges the country had made under the Paris Agreement and the functional end of the global goals that agreement established among nearly all the world’s nations.

Les 10% des personnes les plus riches de la planète sont responsables des deux tiers du réchauffement climatique depuis 1990, selon une étude quantifiant pour la première fois l'impact de la concentration des richesses privées sur les événements climatiques extrêmes.

The nation’s top banks are quietly advising their clients on how to build a financial life raft — or perhaps life yacht — from the wreckage of runaway climate change. Make no mistake: The forecasts coming from Wall Street’s leading financial institutions are bleak. But they also point their clients to potential profit-making opportunities from the havoc spreading across the planet, writes Corbin Hiar.

Climate change is driving rising global temperatures, ecological degradation, and widespread human suffering. Yet, as a collective, humanity has failed to implement sufficient changes to mitigate these threats. This paper introduces the concept of “global narcissism” as a speculative lens to analyze the psychological barriers to climate action. By examining different levels of narcissism and their manifestations in human responses to climate change, this framework highlights key obstacles to meaningful action. While humanity is diverse, and lived experiences vary greatly, this perspective offers a way to discuss patterns of response and resistance. A central challenge lies in humanity’s difficulty in recognizing its symbiotic relationship with the non-human world. Through the metaphor of “global narcissism” this paper explores how humanity’s response to ecological crisis mirrors narcissistic defense mechanisms and suggests a collapse is taking place. This framework provides insights into how psychological int

Paper in Nature Climate Change journal reveals major role wealthy emitters play in driving climate extremes. The world’s wealthiest 10% are responsible for two-thirds of global heating since 1990, driving droughts and heatwaves in the poorest parts of the world, according to a study.

Climate change deaths are largely underreported as the crisis impacts millions and strains an already overburdened healthcare system, according to a new Amnesty International report.

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.

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.

Springtails 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.

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.

The planet is edging close to irreversible change, according to the most comprehensive probability analysis yet of climate “tipping points.”

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.
