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

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

Cost of environmental damage will be six times higher than price of limiting global heating to 2C, study finds

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.

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.

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.

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.

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.

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.

The method used to conduct an attribution study consists of eight steps, described here. The first step is the selection of an extreme event to study. After selecting an extreme weather event to study, the first step is to define the event, which provides a framework for the study. Researchers determine the geographical boundaries of the most impacted area, the best index to quantify the meteorological extreme (eg. maximum temperature, average rainfall, etc), and the duration of the event.

Following a record hot June, large areas of the US and Mexico, Southern Europe and China experienced extreme heat in July 2023, breaking many local high temperature records.
