Guardian investigation reveals fossil fuel links of IPCC authors, with experts declaring the body’s conflict of interest policy ‘not fit for purpose’
One of the biggest upheavals in a millennium is on its way, strengthened by the climate crisis. We need leaders who make things better not worse
Without continued investment in these fields, the world would lose the equivalent of Brazil and Norway’s combined production from the global oil balance each year
Lethal temperatures and wildfires have exposed a widening gulf between voters demanding action and politicians unwilling to confront the long-term choices global heating requires
Les grandes puissances déploient des initiatives de connectivité qui redessinent la carte du monde. La Chine avec ses Nouvelles Routes de la soie, l’Union européenne et son Global Gateway, les États-Unis et le G7 à travers le Build Back Better World ou B3W/PGII… Tous ces projets traduisent une même ambition : organiser, sécuriser et contrôler l’internationalisation de l’économie, plutôt que la subir.
Une sécheresse des sols comme celle que connaît actuellement la Belgique est onze fois plus probable aujourd’hui qu’avant le réchauffement climatique. C’est ce qu’il ressort d’une nouvelle étude du consortium international "World Weather Attribution" (WWA). Explications.
La chaleur extrême, davantage que le manque de précipitations, est en train de devenir le principal facteur de sécheresse sur le continent européen, selon une étude du réseau de scientifiques World Weather Attribution publiée jeudi.
Combien y a-t-il d'habitants dans le monde ? La population mondiale a atteint 8 milliards le 15 novembre 2022 selon les Nations Unies. Compteur de la population mondiale en direct avec fiches de données, graphiques, cartes et données de recensement concernant les chiffres actuels, historiques et futurs de la population mondiale, les estimations, les taux de croissance, les densités et la démographie
Alors que la Chine et les États-Unis se livrent une guerre sans merci sur le terrain de l’intelligence artificielle, le président Xi Jinping a fait une déclaration assez surprenante lors de l’ouverture de la récente World AI Conference (WAIC) à Shanghai. Le dirigeant a proposé de faire en sorte que l’IA devienne un « bien public mondial » via des modèles open-source, une vision contrastant fortement avec celle des Etats-Unis.
Pour les scientifiques du World Weather Attribution, qui analysent le rôle du changement climatique dans les phénomènes météorologiques extrêmes, la vague de chaleur actuelle est directement liée au réchauffement causé par les émissions humaines de gaz à effet de serre. Une nouvelle alerte, qui confirme que ces épisodes extrêmes sont amenés à se multiplier et à s’intensifier avec le dérèglement climatique.
Le 4 juin dernier, le World Inequality Lab (WIL) a lancé le « Global Justice Project », un programme destiné à « stimuler la recherche, l’élaboration des politiques et l’engagement citoyen afin de façonner un 21ème siècle plus juste, plus démocratique et plus durable ». Pour l’heure, il prend la forme d’un rapport, A Plan for Equality & Prosperity Within Planetary Boundaries, qui prolonge sept working papers du WIL – près de 970 pages de travail scientifique. L’effort est colossal. Comme le résume l’un des co-auteurs de l’étude, l’économiste Lucas Chancel, spécialiste des inégalités (Insoutenables inégalités, 2021) et de l’énergie (Énergie et inégalités, 2025) : « 24 mois de travail, 45 chercheurs venus du monde entier, combinant les connaissances issues de l’économie, de l’histoire et des sciences du climat ». À l’échelle de l’histoire de la macroéconomie, c’est l’équivalent d’une pyramide.
La vague de chaleur qui accable l'Europe depuis plusieurs jours aurait été "quasiment impossible" il y a 50 ans et le changement climatique en est "incontestablement" la cause, affirme le World Weather Attribution (WWA) dans une analyse "rapide" publiée vendredi.
Misschien is het probleem niet dat toekomstscenario's zoals die van het Global Justice Report onhaalbaar zijn, maar dat ze net iets te veel vragen stellen over onze huidige realiteit.
L’humanité peut améliorer les niveaux de vie, réduire les inégalités et maintenir le réchauffement climatique en dessous d’une hausse de 2 °C, selon une vision ambitieuse de la survie de la planète rapportée la semaine dernière par The Guardian. À une époque marquée par l’angoisse écologique, c’est une affirmation remarquablement optimiste. Cet optimisme provient du Global Justice Report, élaboré par le World Inequality Lab de Thomas Piketty. […] Ce rapport va à contre-courant de l’époque actuelle. La démagogie anti-immigration, le retour en grâce des combustibles fossiles, les attaques contre le multilatéralisme et la captation du pouvoir par les milliardaires s’opposent tous à la capacité redistributive de l’État que le rapport juge nécessaire. Pourtant, l’équipe du professeur Piketty affirme que la décarbonation, la « sobriété » et l’égalité peuvent permettre à la majorité de mener une vie agréable.
- Artificial intelligence could pose a "more urgent" threat to humanity than climate change, AI pioneer Geoffrey Hinton told Reuters in an interview on Friday. Geoffrey Hinton, widely known as one of the "godfathers of AI", recently announced he had quit Alphabet, opens new tab after a decade at the firm, saying he wanted to speak out on the risks of the technology without it affecting his former employer.
Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says
World is approaching point where no one can shut down a rogue AI, says director of body behind research
Y a-t-il un lien entre le plastique et les ouragans Sandy et Katrina, aux États-Unis, la fonte des glaciers dans l’Antarctique, les vagues de chaleur pendant l’été, l’érosion du littoral en Australie — et quantité d’autres catastrophes naturelles qui s’abattent sur nous avec une fréquence accrue ? Nous incriminons le changement climatique. Mais l’impact des déchets plastiques et de l’industrie du plastique sur le changement climatique est souvent méconnu ou, pire, pris à la légère.
A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.
Les systèmes d’intelligence artificielle générative, qui parlent si bien, ne comprennent pas encore le monde. De nouvelles méthodes physiques ou statistiques comme les world models, ou « modèles de monde », permettraient de les doter d’une forme de sens commun, qui leur servirait à mieux simuler la réalité et de mieux interagir avec elle.
Closed-door talks over the World Bank’s climate agenda have stalled, as the US pushes to scrap green targets and expand support for fossil fuels
Oil has empowered capitalism, and some of the world’s most exploitative regimes. Move away from it and we can solve some of the key issues we face
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.
Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world
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.
HAMBOURG — Depuis quelque temps déjà, les climatologues débattent d’une hypothèse inquiétante : le réchauffement climatique est-il en train de s’accélérer ? La Société allemande de physique et la Société météorologique allemande mettent désormais en garde contre ce phénomène dans une déclaration commune. L’hebdomadaire allemand Die Zeit s’est entretenu à ce sujet avec Klaus Richter, président de la Société allemande de physique, et Frank Böttcher, président de la Société météorologique allemande.
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 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.
Flagship report calls for fundamental reset of global water agenda as irreversible damage pushes many basins beyond recovery
Like living beyond your financial means, using more water than nature can replenish can have catastrophic results.
US demand to own Greenland leaves little scope for compromise, and forcing the issue would entail end of Nato Greenland, with a population of fewer than 57,000, might not seem to be the territory on which the future of the relationship between Europe and the US, the viability of Nato as the world’s most successful defence alliance, or even the fractured relations between the UK and Europe would be determined. But battlefields are sometimes the product of chance, rather than choice. It now feels as if Donald Trump’s threat to impose 10% tariffs on eight fellow Nato states for sending troops last week to support Greenland’s sovereignty may be one of those clarifying moments in which Europe had no option. Successive European leaders condemned Trump’s blackmail and intimidation on Sunday and they sounded as if they meant it.
Satellite analysis warns that widespread land subsidence threatens 1.6 billion people by 2040, with 86% of the at-risk population concentrated in Asia
The “Fueling Ecocide” investigation, led by Environmental Investigative Forum (EIF) and European Investigative Collaborations (EIC), reveals that oil and gas licences overlap with 7,000 protected areas worldwide. The total overlap is 690,000 km², an area bigger than the size of France — despite existing regulations and ongoing efforts to safeguard key biodiversity zones.
From floods to droughts, erratic weather patterns are affecting food security, with crop yields projected to fall if changes are not made
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.
Data from World Inequality Report also showed top 10% of income-earners earn more than the other 90%
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
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.
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.
Antibiotic use in farming is now rampant. How meat is produced in China may mean the drugs you need here won’t work, says Prof Devi Sridhar, chair of global public health at the University of Edinburgh
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.
German scientists warn global warming is accelerating faster than expected, raising the risk of a 3 °C rise by 2050 and forcing Europe to confront unthinkable adaptation plans.
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
A UN commission has found Israel’s war in Gaza ranks among history’s greatest crimes. The UK government must stop hiding behind legal fictions and recognise the reality
De door de mens veroorzaakte klimaatverandering maakte de droogte die Zuid-Europa dit voorjaar trof 10 keer waarschijnlijker. Dat besluiten klimaatwetenschappers van het collectief World Weather Attribution. Die droogte leidde tot verwoestende zomerbranden in onder andere Turkije, Griekenland en Cyprus. Als de klimaatverandering zich verder doorzet, dreigen zulke megabranden nog veel alledaagser te worden dan ze vandaag al zijn.
This is not a call to despair, but an invitation to understand the forces driving the process of collapse, and to explore how we might navigate the descent with integrity, purpose, and care for the living world.
Almost 100 countries reject draft treaty as ‘unambitious’ and ‘inadequate’
The author of Empire of AI: Inside the Reckless Race for Total Domination discusses the cost of Big Tech’s huge investment in technologies that may do more harm than good
Extreme heat is breaking records around the world, with wildfires and poor air quality compounding the crisis, according to a report from the World Meteorological Organization (WMO) released Thursday.
Forests have historically acted as a reliable planetary thermostat. They regulate Earth’s temperature by removing carbon dioxide (CO2) from the atmosphere and locking it in trees, roots and soil — carbon that is emitted if trees are cut down. In a typical year, forests and other vegetation absorb roughly 30% of the carbon that humans emit from burning fossil fuels — a vital climate service performed at virtually no cost by trees around the world, from tropical rainforests to temperate and boreal forests.
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.
António Guterres says ‘sun is rising on a clean energy age’ as 90% of renewable power projects cheaper than fossil fuels
Just three decades ago, Kabul’s population was less than 2 million, but the toppling of the Taliban in 2001 led to an influx of migrants, lured by the promise of increased security and economic possibility. As its population grew, so did the demand for water. Kabul relies almost entirely on groundwater, replenished by snow and glacier melt from the nearby Hindu Kush mountains. But years of mismanagement and over-extraction have caused those levels to drop by up to 30 meters over the last decade, according to Mercy Corps.
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.
Les systèmes d’intelligence artificielle capables, comme ChatGPT, de répondre aux questions des internautes, aspirent à ringardiser les moteurs de recherche traditionnels et à rendre facultative la consultation de sites Internet. Dans ces conditions, que va-t-il rester du World Wide Web ?
The world has been too optimistic about the risk to humanity and planet – but devastation can still be avoided, says Timothy Lenton
Iran’s parliament approved a measure to close the vital global trade route, through which more than a fifth of the world’s oil supply passes through daily
When a small Swedish town discovered their drinking water contained extremely high levels of Pfas, they had no idea what it would mean for their health and their children’s future
The growth in US power demand is surging to its highest rate in decades, driven first by the electrification of oil and gas production and then by the build out of data centers. While still below the 5-10% growth seen in China, the world’s first “electrostate," the US power sector is experiencing rapid structural growth. The country is delivering more than a 3.5% annual power demand growth rate for the first time in several decades, potentially positioning the US as the world’s next “electrostate,” despite the strong oil and gas focus of the Trump administration.
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
Breaching threshold would ramp up catastrophic weather events, further increasing human suffering
Selon une alerte du réseau scientifique World Weather Attribution (WWA), ce mercredi 11 mai, cette fonte accélérée serait le résultat d’une vague de chaleur record entre le 15 et le 21 mai, qui a aussi touché l’Islande.
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
The Ocean is essential to life on Earth, regulates the climate, supports rich biodiversity, sustains livelihoods, and inspires cultures and societies. However, unregulated human impacts are putting the Ocean and its ability to contribute to humanity at risk. The Starfish Barometer is a new initiative launched on World Ocean Day (8 June 2025) to provide a concise, science-based annual overview of the multiple dimensions of the Ocean through the lens of its interdependence with humanity. Each year, the Starfish Barometer will present a carefully curated selection of Ocean-related developments, chosen for their global significance and grounded in the most up-to-date scientific evidence, intended for a broad non-specialist audience. Rather than offering an exhaustive review, it will spotlight key aspects, robust, evidence-based, and reflective of major developments of the year. The Starfish Barometer emphasizes the two-way relationship between humanity and the Ocean: we impact its future, and it shapes ours. Its
Selon l’étude annuelle «World Wealth Report» de Capgemini, la fortune des plus aisés a dépassé les 90 000 milliards de dollars en 2024. Un record depuis 1997 et la première publication de ce rapport annuel.
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.
2024 was the first single year to surpass the 1.5°C global warming threshold – now scientists predict that a year above 2°C is possible in the near future
The world's largest polluters are also the safest from the environmental damage they help create—while the countries least to blame face the greatest threats, including the increased possibility of violent conflict.
Now that the collapse of our political, economic, social and ecological systems is accelerating, the signs of this collapse, including scapegoating, corruption, and social disorder are becoming more obvious. This is the seventh of a series of articles on some of these signposts.
Acute global food insecurity rose for the sixth year in a row in 2024, according to the 2025 Global Report on Food Crises (GRFC), a collaborative effort coordinated by the Food Security Information Network. The report shows that climate extremes, conflict, forced displacement and economic shocks continue to drive malnutrition and food insecurity around the world, with disastrous impacts on those living in many of the most vulnerable regions in the world.
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.
Only 6.9% of the 106 billion tonnes of materials used annually by the global economy come from recycled sources—a 2.2 percentage point drop since 2015, according to a new report released today by Circle Economy in collaboration with Deloitte Global. The Circularity Gap Report 2025 (CGR®) finds that global material consumption is outpacing population growth and generating more waste than recycling systems can handle—underscoring the need for global circular economy targets, system-level transformation, and multilateral collaboration.
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.
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.
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.
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.
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.
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.
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.
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 world is warming despite natural fluctuations from the El Niño cycle.
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
As of February 22, over twenty Stand Up for Science protests are scheduled for March 7 throughout the United States. The protests are being organized by fellow scientists who are concerned about the Trump administration’s feelings and actions towards science (see Robles-Gil, 2025 in Science), includ

Elon Musk has achieved astonishing power in Trump’s administration – and spent the weekend wielding it
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%.
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’s addiction to fossil fuels is a “Frankenstein’s monster sparing nothing and no one”, the UN secretary general, António Guterres, told leaders at the World Economic Forum in Davos on Wednesday. “Our fossil fuel addiction is a Frankenstein’s monster, sparing nothing and no one. All around us, we see clear signs that the monster has become master,”
While some progress has been made in limiting greenhouse gas emissions, we are still on the path for high levels of global warming
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.
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.
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.
People around the world suffered an average of 41 extra days of dangerous heat this year because of human-caused climate change. The figure comes from analysis done by researchers at World Weather Attribution and Climate Central. In 2024 climate records were shattered as heat across the globe made it likely to be the hottest year ever measured, with few countries spared fatal weather events.
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.
Over 2.5 billion people depend on aquifers for fresh water, but rising seas and climate change are pushing saltwater into these crucial reserves.
Three leading climate scientists have combined insights from 10 global climate models and, with the help of artificial intelligence (AI), conclude that regional warming thresholds are likely to be reached faster than previously estimated.
A rainforest might look intact in satellite images – but the reality is often different. Degraded tropical rainforests are now the norm, threatening the species within.
Added complexity allows an economy to grow, even as resource limits are reached. But at some point, the complexity itself becomes a problem.
A Trump presidency can delay, but not stop, the global transition to renewable energy, but it may more effectively stymie progress than during his first term.
A new declaration aims to make the southernmost continent an autonomous legal entity, akin to a nation-state, with inherent rights to participate in decision making that affects it.

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
We, the undersigned, are scientists working in the field of climate research and feel it is urgent to draw the attention of the Nordic Council of Ministers to the serious risk of a major ocean circulation change in the Atlantic. A string of scientific studies in the past few years suggests that this risk has so far been greatly underestimated. Such an ocean circulation change would have devastating and irreversible impacts especially for Nordic countries, but also for other parts of the world.
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.
High-level policy discussions have built momentum for “food system transformation” that would help farmers address the climate crisis.
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.
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.
Blackened trees, dead animals and scorched earth – early wildfires have already devastated Brazil’s Pantanal and local people worry they may lose the battle to save them
In Virginia, a small conservation group is leading the fight against the powerful and secretive data center industry.
Le changement climatique bouscule le quotidien de nombreuses communes qui doivent faire le choix d’abandonner certaines activités ou projets majeurs sur le territoire. Un renoncement parfois difficile, mais qui, pour les maires est indispensable pour penser l’avenir et engager une transformation écologique.
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.
This year elections are taking place across the globe, covering almost half of the world’s population. It is also likely to be, yet again, the hottest year recorded as the climate crisis intensifies. The Guardian asked young climate activists around the world what they want from the elections and whether politics is working in the fight to halt global heating.
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
Exclusive: Survey of hundreds of experts reveals harrowing picture of future, but they warn climate fight must not be abandoned
Outgoing special rapporteur David Boyd says ‘there’s something wrong with our brains that we can’t understand how grave this is’
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.
Cost of environmental damage will be six times higher than price of limiting global heating to 2C, study finds
The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?
L’atome a le vent en poupe ? Peut-être mais cela reste à prouver. Selon le dernier rapport World Nuclear Industry Status Report, le nucléaire est désormais un marché de niche, dominé par deux pays.
You would think that we have more than sufficient troubles caused by global warming, pollution, resource depletion, biodiversity loss, ecosystem disruption and a few more. But there is a problem that’s not directly related to the natural world, but by a purely human construction: the financial market. Here is a discussion by Ian Schindler — maître de conference émérite (emeritus professor of mathematics) at the University of Toulouse 1, France, who proposes that we are close to a financial collapse.
Critical tipping points in the climate system are the flies in the ointment when it comes to accurate prediction of where our planet is headed

In a world built by plutocrats, the powerful are protected while vengeful laws silence their critics
(02/02) - George MonbiotIn the UK and around the world, those who challenge rich corporations are being hounded and crushed with ever-more inventive penalties, says Guardian columnist George Monbiot
Belangrijkste les van het Wereld Economisch Forum? De klimaatproblematiek en het verlies aan natuur zijn een enorme bedreiging voor de bedrijfswereld. Heel wat CEO’s zijn zich daar intussen van bewust, maar de politiek moet nu het juiste kader scheppen, schrijft Julie Vandenberghe van WWF-België.
This report written by the World Economic Forum, in collaboration with Oliver Wyman, provides an in-depth economic analysis of how climate change will reshape health landscapes over the next two decades. It highlights increased risks from new pathogens, pollution and extreme weather events and shows how these will exacerbate current health inequities, disproportionately impacting the most vulnerable populations.
Climate records tumbled "like dominoes" in 2023, with temperatures far above any recorded level.
Als we binnen de grenzen van onze planeet streven naar welzijn voor iedereen, moeten we dringend nadenken over de manier waarop we onze grondstoffen en natuurlijke bronnen waarderen. Dat schrijft Mathias Schluep, algemeen directeur van het World Resources Forum.
Without a phase out of fossil fuels, by 2100, 1 in 12 hospitals worldwide will be at high risk of total or partial shutdown from extreme weather events — a total of 16,245 hospitals. Without a phase out of fossil fuels, all of these 16,245 hospitals will require adaptation, where suitable. Even with this enormous investment, for many, relocation will be the only option.
The effect of increasing the concentration of atmospheric carbon dioxide (CO2) on global average surface air temperature might be expected to be constant, but this is not the case. A study published in the journal Science shows that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere.
Une longue file d'attente qui serpente à l'entrée du site, aux portes du désert: la dure réalité de la popularité des COP s'est imposée aux dizaines de milliers de délégués, observateurs et journalistes accrédités à la COP28 de Dubaï.
L’équipe STEEP de l’INRIA Grenoble a pris l’initiative de populariser les questions que nous posent aujourd’hui le rapport The limits to growth et le modèle World3 issus de la commande du club de Rome à Dennis et Donella Meadows et leur équipe du MIT en 1972. Alors que 50 ans se sont écoulés depuis sa publication, nous avons constaté que peu de personnes du grand public, mais aussi de collègues en SHS, mais aussi parfois en sciences dures, connaissaient effectivement ce moment important de la pensée systémique sur les questions de modèle de croissance engageant des modes de vie. Son titre alors que nous devons faire face à une crise majeure liée à la non prise en compte des limites planétaires pointées pourtant dans ce rapport, mais aussi en amont, nous oblige.
After 50 years, there is still an ongoing debate about the Limits to Growth (LtG) study. This paper recalibrates the 2005 World3-03 model. The input parameters are changed to better match empirical data on world development. An iterative method is used to compute and optimize different parameter sets. This improved parameter set results in a World3 simulation that shows the same overshoot and collapse mode in the coming decade as the original business as usual scenario of the LtG standard run. The main effect of the recalibration update is to raise the peaks of most variables and move them a few years into the future. The parameters with the largest relative changes are those related to industrial capital lifetime, pollution transmission delay, and urban-industrial land development time.
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 starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”
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.
Earth just had the hottest September on record – and by a record-breaking margin, according to leading international datasets which are used by the World Meteorological Organization (WMO) for its State of the Global Climate monitoring reports.
In the past two years Les Soulèvements de la Terre, a network of ecological activists and groups, has used direct confrontations with polluters and developers to threaten industrial agriculture’s monopoly on the French countryside.
De son côté, le prince Abdulaziz bin Salman, ministre saoudien de l'énergie, a tenté de saper les dernières prévisions de l'Agence internationale de l'énergie selon lesquelles la demande mondiale de combustibles fossiles atteindrait le Pic Oil d’ici à 2030, alors que les énergies renouvelables, moins chères et plus propres, augmentent rapidement. Il est clair que si l’AIE annonce un pic oil, certains pays vont réfléchir à deux fois à continuer dans le pétrole et les investisseurs vont se gratter la tête.
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.
Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more
If you've ever seen the movie Soylent Green, you know it's not about cannibalism. It's about the banality of social collapse. It's not quick. It's a slow burn. Nobody shows any sense of urgency about anything. Everyone still watches talk shows, even if they have to pedal a bike to generate electricity for their television. Nobody under 50 remembers anything better. Here's the plot twist: It's not that corporations are using people as the main ingredient in everyone's favorite new food. It's
Bonn and Geneva, 6 September 2023 (ECMWF and WMO) - Earth just had its hottest three months on record, according to the European Union-funded Copernicus Climate Change Service (C3S) implemented by ECMWF. Global sea surface temperatures are at unprecedented highs for the third consecutive month and Antarctic sea ice extent remains at a record low for the time of year.
Comme l'a expliqué Mme Von der Leyen, les États membres de l'UE devront faire des contributions complémentaires au budget de l'UE, à hauteur de 66 milliards d'euros au total. il se retrouve aujourd’hui pratiquement sans financement, en raison de l’aide « somptueuse » accordée à l’Ukraine. La Commission ne dispose plus que de tout juste 82,5 milliards d’euros. Des clopinettes ! Le programme vert devrait donc disparaître de la scène politique.
The UN Secretary-General’s Early Warnings for All Initiative (EW4All) is rapidly gaining ground. Action plans are being rolled out around the world to ensure that people know when dangerous weather is headed their way. Tajikistan has held a two-day national consultation, co-chaired by the Deputy Prime Minister and the UN Resident Coordinator in Tajikistan, and bringing together key stakeholders from state and international organizations, media and civil society. Ethiopia also held an inception workshop.
New data on WRI's Aqueduct platform ranks the world's most water-stressed countries. One-quarter of the global population regularly use up their entire water supply.
Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback. However, the scientific revolution and the use of fossil fuels reduced many forms of negative feedback, enabling us to realize our full potential for exponential growth. This natural capacity is being reinforced by growth-oriented neoliberal economics—nurture complements nature. Problem: the human enterprise is a ‘dissipative structure’ and sub-system of the ecosphere—it can grow and maintain itself only by consuming and dissipating available energy and resources extracted from its host system, the ecosphere, and discharging waste back into its host. The population increase from one to eight billion, and >100-fold expansion of real GWP in just two centuries on a finite planet, has thus propelled modern techno-industrial society into a state of advanced overshoot. We are consuming and
De extreme hittegolven deze maand in grote delen van de VS, Zuid-Europa en China zouden ‘vrijwel onmogelijk’ geweest zijn zonder de door de mens veroorzaakte klimaatverandering. Dat is de conclusie van het World Weather Attribution-initiatief (WWA).
According to ERA5 data from the EU-funded Copernicus Climate Change Service (C3S), the first three weeks of July have been the warmest three-week period on record and the month is on track to be the hottest July and the hottest month on record. These temperatures have been related to heatwaves in large parts of North America, Asia and Europe, which along with wildfires in countries including Canada and Greece, have had major impacts on people’s health, the environment and economies.

And what we need to do it right,
Without more legally binding and well-planned net-zero policies, the world is highly likely to miss key climate targets.
A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough--such as by using a model--wind and solar look to be useful. They don't burn fossil fuels, so it appears that they might be helpful to the environment. Energy modeling misses important points. I believe that profitability signals are much more important.
La CSRD, dont les standards sont en discussion en ce moment dans les instances européennes, pourrait être finalement vidée de sa substance et de son ambition. Le texte, qui représentait un progrès significatif en matière d’obligations RSE et notamment d’obligation de reporting, est en ce moment l’objet d’une opposition vigoureuse des groupes d’intérêt et des lobbies, qui tentent d’affaiblir le texte. Alors, est-ce la fin annoncée de ce texte pourtant fondateur pour la responsabilité des entreprises opérant en Europe ? Revenons sur les dernières évolutions des discussions autour de la CSRD.
Inégalités environnementales et inégalités sociales sont deux facettes d’une même crise : celle de notre système économique. Les plus pauvres sont les plus touchés par la crise climatique, et la précarité verrouille souvent la transition écologique. Voilà pourquoi la transition doit être écologique, mais aussi sociale.
