The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.

Climate models show considerable discrepancies in their future projections around the Atlantic, mainly due to uncertainties in the fate of the Atlantic Meridional Overturning Circulation (AMOC). Climate models suggest a reduction in AMOC strength of 32 ± 37% by 2100 (90% probability, Shared Socioeconomic Pathways 2-4.5 scenario, Coupled Model Intercomparison Project Phase 6). To refine this estimate and reduce its uncertainty, we use four different observational constraint methods. The best one, which provides the lowest leave-one-out error, integrates a large set of observable variables using ridge-regularized linear regression—a method unusual in climate science. It gives an estimate of the AMOC slowdown of 51 ± 8% (90% probability), i.e., a weakening ∼ 60% stronger than suggested by the multimodel mean. This refinement mainly results from correcting a bias in South Atlantic surface salinity, consistent with recent studies emphasizing its role in the proximity to an AMOC tipping point. This more substantial

Wildfires used to die down and even stop at night with cooler temperatures and increased humidity. But a study released Friday says climate change is making burning weather more around the clock in North America because night is becoming warmer and drier. Canadian fire scientists say potential burning hours for fires have increased 36% in the last 50 years. California now has about 550 more fire-friendly hours a year than it did in the 1970s. North American summer nights are warming faster than days, evening relief is evaporating for forests and that means the area of land burned is soaring.

The European Center for Medium Range Weather Forecasts (ECMWF) earlier this year issued a forecast of a strong (“Super”) El Nino to begin later this year and peak in early 2027, as we have discussed in two earlier posts.3,4 El Ninos are important because of the large effects that they have on global weather, even though those effects are not always consistent from one El Nino to another. El Ninos have even greater effect in combination with ongoing global warming, e.g., Radfar et al.5 find that the combination of an El Nino with increasingly prevalent marine heat waves results in tropical cyclones consistently producing higher maximum wind speeds, storm surges, and precipitation rates, and Liu et al.6 describe evidence of El Ninos strengthened control over global climate anomalies in a warmer world

Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti

Most research on “forever chemicals” focuses on how best to remove them from the environment. But solutions to tricky problems often emerge from the most unexpected of places—as demonstrated by a new study that instead redirects the pollutants into becoming tools for extracting precious lithium. In a recent Nature Water study, a team led by Rice University researchers describes a novel way to use spent perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to recover lithium from high-salinity brine pools. The team tapped into the fluorine content inside PFAS leftovers, using it to attract lithium from briny water. Remarkably, the team was able to collect lithium fluoride at 99% purity and confirmed that the sample was pure enough to boost the stability and performance of lithium-ion batteries.

Seven Ukrainians arrested and money-laundering investigation launched in latest spat between Kyiv and Budapest

What is currently happening in Brussels under the guise of regulatory simplification is being presented as something technical and logical. Less regulatory pressure, more competitiveness. A series of so-called omnibus bills are intended to streamline legislation. Reporting obligations are being limited and reassessments of raw materials postponed. It sounds like administrative efficiency. In Washington, things are moving even faster: Trump is dismantling the basis for climate laws while the world continues to warm up. The framing is the same: rules slow down businesses, and a slowed-down business community makes us poor. But that reasoning assumes something that is not true: that everyone wants the same thing from the market.

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.

New year, new acronym! The newly established Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution (ISP-CWP) will meet in its first Plenary session from February 2-6 in Geneva, Switzerland. The Panel is designed to provide scientific assessments on chemicals, waste, and pollution to inform policymakers at national, regional, and international levels.

Testimony from medics, morgue and graveyard staff reveals huge state effort to conceal systematic killing of protesters

The decline in the health of nature around the world poses a threat to the UK's security and prosperity, an intelligence committee has concluded in a long-awaited report. The document warns of "cascading risks" from the degradation of some of the planet's most important ecosystems, including conflict, migration and increased competition for resources.

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

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

A deal is welcome after talks nearly collapsed but the final agreement contains small steps rather than leaps

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petroleum-based waste and heavy metals have been discovered in pesticide and plasticizer formulations. These contaminations have now reached all forms of life. Widespread exposure to chemical mixtures promotes health and environmental risks. We discovered that pesticides have never undergone long-term testing on mammals in their full commercial formulations by regulatory authorities or the pesticide industry; instead, only their declared active ingredients have been assessed, contrary to environmental law recommendations. The ingredients of these formulations are not fully disclosed, yet the formulations are in general at least 1000 times more toxic at low environmentally relevant doses than the active ingredients alone u

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.

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.

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.

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.

Collapse has historically benefited the 99%. […] That’s the amazing conclusion of Luke Kemp, author of Goliath’s Curse: The History and Future of Societal Collapse.  Luke is a research associate at the Centre for the Study of Existential Risk at the University of Cambridge, and has spent the past five years studying the collapse of civilisations throughout history. He joins me to explain his research, detailing the difference between complex, collective civilisations and what he calls “Goliaths”, massive centralising forces by which a small group of individuals extract wealth from the rest through domination and the threat of violence. Today, he says, we live in a global Goliath.

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.

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

The Production Gap Report finds that 10 years after the Paris Agreement, governments plan to produce more than double the volume of fossil fuels in 2030 than would be consistent with limiting global warming to 1.5°C, steering the world further from the Paris goals than the last such assessment in 2023.

Much attention today focuses on uncertainties affecting the future evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances. The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook. This new report – based on analysis of the production records of around 15 000 oil and gas fields around the world – explores the implications of accelerating decline rates, growing reliance on unconventional resources, and evolving project development patterns for the global oil and gas supply landscape, for energy security and for investment. It also provides regional insights

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.

Purpose Animal emissions account for nearly 60% of total greenhouse gas emissions from the livestock sector. To estimate these emissions, the Food and Agriculture Organization of the United Nations (FAO) developed a dedicated module within the Global Livestock Environmental Assessment Model (GLEAM). Although previous studies have explored selected inputs for specific animals and emission types, a comprehensive analysis of all 92 inputs (parameters and emission factors) had not been conducted. This study aimed to identify the most influential inputs affecting ruminant emissions in GLEAM.

The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.

The climate crisis has entered a decisive phase. Delaying climate measures increases the likelihood of crossing tipping points. Political shifts are weakening international cooperation when unity is vital. Yet, the Planetary Boundaries offer a path to a stable and sustainable future.

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

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.

Russia’s war in Ukraine has encouraged a rapid increase in the deployment of drones that use fibre optic cables to protect them from being jammed or downed by electronic warfare: the drones trail kilometres of plastic cable across frontlines. In this post Leon Moreland explores the environmental risks posed by this new form of battlefield plastic pollution.

Depuis quelques jours, plusieurs médias et politiques s’émeuvent d’une prétendue «interdiction» du comté souhaitée par «les écologistes». Derrière la polémique, des associations et scientifiques s’inquiètent des dégâts environnementaux dont est en partie responsable la production de ce fromage, malgré les efforts de la filière pour y remédier.

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.

No one knows when the next alert or request to save a chunk of US government-held climate data will come in. Such data, long available online, keeps getting taken down by US President Donald Trump's administration. For the last six months or so, Cathy Richards has been entrenched in the response. She works for one of several organisations bent on downloading and archiving public data before it disappears.

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".

Bayer, the corporation behind Roundup herbicide, has paid out nearly $11 billion in lawsuits. Trump’s EPA might move to block the suits.

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).

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.

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

As of February 22, over twenty Stand Up for Science protests are scheduled for March 7 throughout the United States.

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.

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.

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.

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.

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

Some narratives in international development hold that ending poverty and achieving good lives for all will require every country to reach the levels of GDP per capita that currently characterise high-income countries. However, this would require increasing total global output and resource use several times over, dramatically exacerbating ecological breakdown. Furthermore, universal convergence along these lines is unlikely within the imperialist structure of the existing world economy. Here we demonstrate that this dilemma can be resolved with a different approach, rooted in recent needs-based analyses of poverty and development. Strategies for development should not pursue capitalist growth and increased aggregate production as such, but should rather increase the specific forms of production that are necessary to improve capabilities and meet human needs at a high standard, while ensuring universal access to key goods and services through public provisioning and decommodification. At the same time, in high

The signs of weakening resilience raise concerns that the world’s greatest tropical forest – and biggest terrestrial carbon sink – is degrading towards a point of no return. It follows four supposedly “one-in-a-century” dry spells in less than 20 years, highlighting how a human-disrupted climate is putting unusually intense strains on trees and other plants, many of which are dying of dehydration.

01 August 2024 – Humanity is facing its greatest emergency, a crisis consisting of many, interlinked, catastrophic risks, the Roundtable on the Human Future has declared. At present humanity has no way to deal with such a crisis – and a global plan of action is urgently needed, it said.

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.

Oil and gas equipment intended to cut methane emissions is preventing scientists from accurately detecting greenhouse gases and pollutants, a satellite image investigation has revealed. Energy companies operating in countries such as the US, UK, Germany and Norway appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions and pollutants at industrial facilities involved in the disposal of unprofitable natural gas, known in the industry as flaring.

The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 percent of the world's biodiversity, helps stabilize the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide.

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.

Policy-makers seeking to limit the impact of coal electricity-generating units (EGUs, also known as power plants) on air quality and climate justify regulations by quantifying the health burden attributable to exposure from these sources. We defined “coal PM2.5” as fine particulate matter associated with coal EGU sulfur dioxide emissions and estimated annual exposure to coal PM2.5 from 480 EGUs in the US. We estimated the number of deaths attributable to coal PM2.5 from 1999 to 2020 using individual-level Medicare death records representing 650 million person-years. Exposure to coal PM2.5 was associated with 2.1 times greater mortality risk than exposure to PM2.5 from all sources. A total of 460,000 deaths were attributable to coal PM2.5, representing 25% of all PM2.5-related Medicare deaths before 2009 and 7% after 2012. Here, we quantify and visualize the contribution of individual EGUs to mortality.

Daniel P. Aldrich (born 1974) is an academic in the fields of political science, public policy and Asian studies. He is currently full professor of political science and public policy at Northeastern University.[1] Aldrich has held several Fulbright fellowships, including a Fulbright Distinguished Chair in Applied Public Policy (Democratic Resilience) at Flinders University in Australia in 2023,[2] a Fulbright Specialist[3] in Trinidad-Tobago in 2018, a Fulbright research fellowship at the University of Tokyo's Economic's Department for the 2012–2013 academic year, and a IIE Fulbright Dissertation Fellowship in Tokyo in 2002–2003. His research, prompted in part by his own family's experience of Hurricane Katrina,[4] explores how communities around the world respond to and recover from disaster.

The world’s first study of the increase in pollution from landscape fires across the globe over the past two decades reveals that over 2 billion people are exposed to at least one day of potentially health-impacting environmental hazard annually – a figure that has increased by 6.8 per cent in the last ten years.

Waves of severe thunderstorms in the U.S. during the first half of this year led to $34 billion in insured losses, an unprecedented level of financial damage in such a short time as climate change contributes to the frequency and severity of violent meteorological events. The reinsurer Swiss Re Group said Wednesday that damages from convective storms in the U.S., which can come with hail, lightning, heavy rain and high winds, accounted for nearly 70% of the $50 billion in global catastrophic damages so far this year. The storms in the U.S. were so severe, there were 10 that resulted in damages of $1 billion or more, almost double the average over the last decade.

Top oil and gas companies have made little progress in turning away from hydrocarbons and towards the goals of the 2015 Paris climate deal, multinational nonprofit platform CDP said on Thursday.

Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests. The paper, published in the journal Nature Sustainability, is entitled "Quantifying the Human Cost of Global Warming."

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.

Named one of the “world’s ten most influential intellectuals” by MIT, Douglas Rushkoff is an author and documentarian who studies human autonomy in a digital age. Rushkoff’s work explores how different technological environments change our relationship to narrative, money, power, and one another. He coined such concepts as “viral media,” “screenagers,” and “social currency,” and has been a leading voice for applying digital media toward social and economic justice. In the conversation we talk about the power of ideas, our disconnection from reality, going meta, ancestral fears, tech billionaires mindset and how they are preparing for the apocalypse. We also reflect on the urgent need to be more human and reconnect with what is essential.

NEW YORK – Bloomberg today released a research paper detailing the development of BloombergGPTTM, a new large-scale generative artificial intelligence (AI) model.

Healthy teenagers are more prone to irregular heartbeats after breathing in fine particulate air pollution, according to the first major study of its impact on otherwise healthy young individuals. The findings have raised concern among researchers because heart arrhythmias, which can increase the risk of heart disease and sudden cardiac death, appear to be triggered even when air pollution is within common air quality limits.

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

Germany’s Rhine, one of Europe’s key waterways, is just days away from being closed to commercial traffic because of very low levels caused by drought, authorities and industry have warned. Crucially, the impending crisis could lead energy companies to cut their output, one of the country’s biggest gas companies has said.

Increasing risks posed by climate change are causing rare extreme events that can kill more than 10 million people or lead to damages of $10 trillion-plus, posing threats of total societal collapse, a UN report finds.

School and university students all over the world are planning to take school strikes one step further and occupy our campuses to demand the end of the fossil economy. Taking a lesson from student activists in the 1960s, the climate justice movement’s youth will shut down business as usual. Not because we don’t like learning, but because what we’ve learned already makes it clear that, without a dramatic break from this system, we cannot ensure a livable planet for our presents and futures.

We have reviewed the first two chapters of the new book Limits and Beyond. The reviews can be found at The Yawning Gap (Chapter 1) and No More Growth (Chapter 2). In this post we take a look at the third chapter, written by Dennis Meadows, a co-author of the original Limits to Growth. Dr. Meadows reports that he has delivered over a thousand speeches to a very wide variety of audiences. In this chapter the author summarizes “19 of the most common questions, comments and objections” that he has received over the years. Some of his insights are as follows:

Ces dernières années, les canicules sont devenues fréquentes, et devraient se multiplier dans les décennies qui viennent, mettant nos corps à rude épreuve. Si quelques jours ne suffisent pas à nos organismes pour s’adapter à la montée du mercure, à très long terme, le réchauffement climatique pourrait orienter l’évolution de l’Homme, comme nous l’explique Alain Froment, anthropologue spécialiste d'écologie humaine.

The IPBES #PandemicsReport is one of the most scientifically robust examinations of the evidence and knowledge about links between pandemic risk and nature since the COVID-19 pandemic began - with 22 of the world's leading experts from fields as diverse as epidemiology, zoology, public health, disease ecology, comparative pathology, veterinary medicine, pharmacology, wildlife health, mathematical modelling, economics, law, and public policy as authors of the report. The expertise of the 22 authors was further augmented by contributions and knowledge resources from the Convention on Biological Diversity, the Intergovernmental Panel on Climate Change, the Convention on International Trade in Endangered Species, the United Nations Convention to Combat Desertification, and the World Health Organization - as well as a peer review process.

Deaths from exposure to emissions from vehicles, smoke stacks and wildfires have increased by more than 50 percent this century, with poorer countries bearing the brunt of the impacts.

What else is new? Hotspots are getting hotter. The major hotspot in April stretched from Iraq to India and Pakistan, and toward the northeast through Russia (Fig. 1). Temperature exceeded 45°C (113°F) in late April in at least nine Indian cities,[1] on its way to 50°C (122°F) in Pakistan in May,[2] where a laborer says “It’s like fire burning all around” and a meteorologist describing growing heatwaves since 2015 says “The intensity is increasing, and the duration is increasing, and the frequency is increasing.” Halfway around the world, Canada and north-central United States were cooler than their long-term average, but people in British Columbia and northwest United States remember being under their own record-breaking hotspot last summer.

The focus of the opening day of the 17th session of the United Nations Forum on Forests (UNFF17) was a High-Level Roundtable on the UNFF response to, role in, and expectations from forest-related multilateral developments. Members of the Forum also started providing updates on their actions in support of the three UNFF thematic priorities for 2021-2022; these will continue on Tuesday.

In 1972, a book changed the world. The Club of Rome commissioned a report that shifted how we see what humans are doing to the planet. Looking back five decades later, what happened next, what did we do and not do, what did we learn, and what happens now? In The Limits to Growth, a team from MIT studied the way humans were using the resources of the earth. Using sophisticated computer modelling, the researchers developed scenarios to map out possible paths for humanity, the global economy and the impact on the planet.

Countries should move from coal to renewable energy without shifting to gas as a “transition” fuel to save money, as high gas prices and market volatility have made the fossil fuel an expensive option, analysis has found. Natural gas has long been touted as a “transition” fuel for economies dependent on coal for their power needs, as it has lower carbon dioxide emissions than coal but requires similar centralised infrastructure, and gas-fired power stations take only a couple of years to build. Earlier this year, before Russia invaded Ukraine, the European Commission angered green campaigners by including gas as a “bridge” to clean energy in its guidebook for green investment.

The fifteenth session of the Conference of the Parties (COP15) of the United Nations Convention to Combat Desertification (UNCCD) will take place in Abidjan, Côte d’Ivoire, from 9 to 20 May 2022.

Presentation of the book "Beyond the Limits," a new report to the Club of Roma edited by Ugo Bardi and Carlos Alvarez Pereira. It tells the story of the 1972 study "The Limits to Growth" and its relevance 50 years later.

The war in Ukraine is laying bare a generational divide over what lessons Germany should draw from its own history of waging bloody conflicts, as some of the country’s leading artists and intellectuals line up in favour of or against supplying Kyiv with weapons in a series of open letters.

Russia has nearly doubled its revenues from selling fossil fuels to the EU during the two months of war in Ukraine, benefiting from soaring prices even as volumes have been reduced.

Center of Bicycle Technology Maya Pedal is a Guatemalan NGO based in San Andrés Itzapa. We accept bikes donated from the USA and Canada which we either recondition to sell, or we use the components to build a range of "Bicimaquinas", (pedal powered machines).

Most marine-terminating glaciers in the Northern Hemisphere are shrinking; some have completely left the water.

Rapid decarbonization of energy is non-negotiable if we are to avert catastrophic global heating, says the latest UN climate report.

Researchers from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences (CAS) and their collaborators published a high-accuracy and high-resolution permafrost map over the Northern Hemisphere.

When the lights went out at Chornobyl Nuclear Power Plant on 9 March, the Russian soldiers holding Ukrainian workers at gunpoint became the least of Anatolii Nosovskyi’s worries. More urgent was the possibility of a radiation accident at the decommissioned plant. If the plant’s emergency generators ran out of fuel, the ventilators that keep explosive hydrogen gas from building up inside a spent nuclear fuel repository would quit working, says Nosovskyi, director of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv. So would sensors and automated systems to suppress radioactive dust inside a concrete “sarcophagus” that holds the unsettled remains of Chornobyl’s Unit Four reactor, which melted down in the infamous 1986 accident.

Environmentalists once saw abstraction as the biggest obstacle to climate action. How, they wondered, could one focus the public on the distant future? Today, we confront the opposite problem, with the very immediacy of the crisis generating a strange paralysis. When the Intergovernmental Panel on Climate Change warned that global heating made extreme flooding more common, its new report at the end of February spurred relatively little discussion – in part because of the water covering swathes of Queensland and New South Wales. As tinnies plucked desperate residents from the deluge, who could give due weight to the warning from Prof Brendan Mackey, one of the IPPC authors, that the science clearly projected “an increase of heavy rainfall events?”

Inflation is a disease that disproportionately afflicts the poor. Even before Vladimir Putin unleashed his brutal war on Ukraine, whose byproducts include soaring energy and food prices, inflation was already over 7.5% in the US and above 5% in Europe and the UK. Calls for its taming are, therefore, fully justified – and the interest rate rise in the US, with the same expected in the UK, comes as no surprise. That said, we know from history that the cure for inflation tends to devastate the poor even more. The new wrinkle we face today is that the supposed solutions threaten not only to deal another cruel blow to the disadvantaged but, ominously, to snuff out the desperately needed green transition.

The Ukrainian crisis has revived an old debate: how to effectively sanction a state like Russia? Let’s say it straight away: it is time to imagine a new type of sanction focused on the oligarchs who have prospered thanks to the regime in question. This will require the establishment of an international financial register, which will not be to the liking of western fortunes, whose interests are much more closely linked to those of the Russian and Chinese oligarchs than is sometimes claimed. However, it is at this price that western countries will succeed in winning the political and moral battle against the autocracies and in demonstrating to the world that the resounding speeches on democracy and justice are not simply empty words.

The war in Ukraine and surging oil prices are other factors that could prompt PBOC action when it announces its policy loan rates Tuesday, as the nation aims to achieve a growth target of 5.5% for the year. The Hong Kong and China stocks sold off Monday, led by losses in technology shares, due to risks from Beijing’s close relationship with Russia and regulatory concerns.

Measures implemented this year could bring down gas imports from Russia by over one-third, with additional temporary options to deepen these cuts to well over half while still lowering emissions.

Momentum to phase out unabated coal use is growing globally. This transition is critical to meeting the Paris climate goals but can potentially lead to large amounts of stranded assets, especially in regions with newer and growing coal fleets. Here we combine plant-level data with a global integrated assessment model to quantify changes in global stranded asset risks from coal-fired power plants across regions and over time. With new plant proposals, cancellations, and retirements over the past five years, global net committed emissions in 2030 from existing and planned coal plants declined by 3.3 GtCO2 (25%). While these emissions are now roughly in line with initial Nationally Determined Contributions (NDCs) to the Paris Agreement, they remain far off track from longer-term climate goals. Progress made in 2021 towards no new coal can potentially avoid a 24% (503 GW) increase in capacity and a 55% ($520 billion) increase in stranded assets under 1.5 °C. Stranded asset risks fall disproportionately on emergin

We submit that the safe operating space of the planetary boundary of novel entities is exceeded since annual production and releases are increasing at a pace that outstrips the global capacity for assessment and monitoring. The novel entities boundary in the planetary boundaries framework refers to entities that are novel in a geological sense and that could have large-scale impacts that threaten the integrity of Earth system processes. We review the scientific literature relevant to quantifying the boundary for novel entities and highlight plastic pollution as a particular aspect of high concern. An impact pathway from production of novel entities to impacts on Earth system processes is presented.

The ground, typically moist from snow this time of year, was dry and flammable as a result of unusually warm temperatures and a lack of precipitation in recent months, experts said.

In January of 2019, Chase Lochmiller and Cully Cavness, recently reunited prep school pals from Denver, drove out to the snow-covered plains of Wyoming to bring a piece of tech culture to the American heartland. Trembling in -20F (-29C) temperatures, they wired up a prototype of their brainchild: a machine that harnesses the “waste gas” from oil rigs to power mining for cryptocurrency.
