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

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.

The Senate is on the verge of taking up a bill with the Orwellian title “Fix Our Forests Act.” It is designed to do the opposite, as Dan Galpern and I describe in an op-ed published yesterday in the Boston Globe, which is copied below with permission of the Globe. The bill would result in swaths of the public’s national forests becoming “categorical exclusion” zones open to logging exempt from any environmental review. Thus, the bill would override the purposes for which national forests were set up, including “outdoor recreation, range…watershed, and wildlife and fish purposes.” This sin is rationalized under the pretense that the Act will reduce wildfire risk and improve forest health by “thinning” the forest. This is nonsense, as our op-ed discusses.

The authors of a new book argue that the ocean cannot be saved by legislation alone. Paul Watson is one of the authors, along with academic Sarah Levy. Watson was an early member of Greenpeace, and founded the Sea Shepherd Conservation Society, but is no longer linked to either organization. While he maintains he has never caused physical injury to anyone, he promotes "aggressive non-violent" direct action, and is currently wanted by the Japanese state.
The world has entered an era of “global water bankruptcy” that is harming billions of people, a UN report has declared. The overuse and pollution of water must be tackled urgently, the report’s lead author said, because no one knew when the whole system could collapse, with implications for peace and social cohesion. All life depends on water but the report found many societies had long been using water faster than it could be replenished annually in rivers and soils, as well as over-exploiting or destroying long-term stores of water in aquifers and wetlands.

“Water crisis” has become the default label for almost any episode of water stress, from short-lived droughts to decades-long overuse of rivers and aquifers. Yet in many regions of the world, water problems no longer resemble a crisis in the conventional sense. They represent a post-crisis failure state in which human–water systems have exceeded their hydrological carrying capacities, and societies have spent beyond their sustainable hydrological budgets for so long that critical water assets are depleted, some ecosystem damages are irreversible on human time scales, and a return to “normal” is infeasible even with prohibitive economic, social, and environmental costs.

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.

Progress of artificial general intelligence could stall, which may lead to a financial crash, says Yoshua Bengio, one of the ‘godfathers’ of modern AI
Melting glaciers, coastal areas wiped off the map and regular 40C heat in Europe. Climate experts warn the gloomy predictions of long term environmental change are no longer the future - they are already here. Last year was the third hottest on record, with the World Meteorological Organization this week warning that 2025 continued a run of “extraordinary” global temperatures. The EU has said the Paris climate agreement of 1.5C could be broken before 2030, a decade sooner than expected.

A new international analysis published in Advances in Atmospheric Sciences on 9 January finds that the Earth's ocean stored more heat in 2025 than in any year since modern measurements began. The finding is the result of a major international collaboration led by the Institute of Atmospheric Physics at the Chinese Academy of Sciences, involving more than 50 scientists from 31 research institutions worldwide. The 2025 heat increase was 23 Zetta Joules (23,000,000,000,000,000,000,000 Joules of energy), which is equivalent to ~37 years of global primary energy consumption at the 2023 level (~620 Exa Joules per year). The assessment combines data from major international data centers and independent research groups, including three observational products (Institute of Atmospheric Physics at the Chinese Academy of Sciences; Copernicus Marine; and NOAA/NCEI) and an ocean reanalysis (CIGAR-RT) from three continents: Asia, Europe, and America. These groups confirm that the 2025 ocean heat content (OHC) reached the h

It has the world's largest reserves, produces comparatively little, and has a type of oil that the US needs. […] Over the weekend, the United States bombed Venezuela, and captured its president Nicolás Maduro. There has been a lot of speculation about the legality, true motive and implications going forward. Oil has been a central part of the discussion. I wanted to get a quick overview of what the global picture looks like. So here are five(ish) simple charts that give some context on the history of oil in Venezuela, and why the United States — which is, by far, the world’s largest producer itself — would care so much.

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

Global temperature in 2025 declined 0.1°C from its El Nino-spurred maximum in 2024, making 2025 the second warmest year. The 2023-2025 mean is +1.5°C relative to 1880-1920. The 12-month running-mean temperature should decline for the next few months, reaching a minimum about +1.4°C. Later in 2026, we expect the 12-month running-mean temperature to begin to rise, as dynamical models show development of an El Nino. We project a global temperature record of +1.7°C in 2027, which will provide further confirmation of the recent global warming acceleration.

Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energy-matter interactions. These constraints stem from the fact that Earth is a materially closed yet energetically open system, driven by the sustained but low power-density flux of solar radiation. This Perspective reframes sustainability within these axiomatic limits, integrating relevant timescales and orders of magnitude. We argue that fossil-fueled industrial metabolism is inherently incompatible with long-term viability, while post-fossil systems are surface-, materials-, and power-intensive. Long-term sustainability must therefore be defined not only by how much energy or material is used, but also by how it is used: favoring organic, carbon-based chemistry with limited reliance on purified metals, operating at low power density, and maintaining low throughput rates. Achieving this requires radical technological shifts toward l

Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the northern hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the sea. Until now, only a very few have been found in the Antarctic. In a new study soon to be published in Geophysical Research Letters, I present evidence for hundreds of these quakes in Antarctica between 2010 and 2023, mostly at the ocean end of the Thwaites Glacier – the so-called Doomsday Glacier that could send sea levels rising rapidly if it were to collapse.

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

Rain-fed agriculture, the backbone of rural livelihoods, are no longer predictable as droughts follows floods.
The growth rate of greenhouse gas (GHG) climate forcing increased rapidly in the last 15 years to about 0.5 W/m2 per decade, as shown by the “colorful chart” for GHG climate forcing that we have been publishing for 25 years (Fig. 1).[1] The chart is not in IPCC reports, perhaps because it reveals inconvenient facts. Although growth of GHG climate forcing declined rapidly after the 1987 Montreal Protocol, other opportunities to decrease climate forcing were missed. If policymakers do not appreciate the significance of present data on changing climate forcings, we scientists must share the blame.

We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth.
22 of the planet’s 34 vital signs are at record levels, with many of them continuing to trend sharply in the wrong direction. This is the message of the sixth issue of the annual “State of the climate” report. The report was prepared by an international coalition with contribution from the Potsdam Institute for Climate Impact Research (PIK) and led by Oregon State University scientists. Published today in BioScience, it cites global data from the Intergovernmental Panel on Climate Change (IPCC) in proposing “high-impact” strategies.

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. In this astounding conversation, Luke takes us from the Ancient times to the modern day, revealing the root causes of collapse and paralleling them what we’re living through today. He explains the egalitarian nature of our species, and shines new light on what a future could look like free from today’s global Goliath. He reminds us all that we tend to view collapse through the eyes of the 1%, those who have the most to lose, and gives startling accounts of how populations bounced back after thei
For the first 300,000 years of human history, hunter-gathering Homo sapiens lived in fluid, egalitarian civilizations that thwarted any individual or group from ruling permanently. Then, around 12,000 years ago, that began to change.
Dr Luke Kemp is a Research Associate at the Centre for the Study of Existential Risk, University of Cambridge. He has a PhD in international relations from the ANU and previous experience as a senior economist at Vivid Economics. This episode explores catastrophic and extinction risk, why the topic is understudied, and how we can weigh out the catastrophic risks of climate change and solar geo-engineering.
Today, Nate is joined by Luke Kemp, a researcher whose work is focused on existential risks (or X-risks), which encompass threats of human extinction, societal collapse, and dystopian futures. How can we begin to understand the likelihood and gravity of these ruinous events, and what kinds of responses from people and governments could further undermine social cohesion and resilience? What roles do human biases, hierarchical power structures, and the development of technologies, like artificial intelligence and geoengineering, play in X-risks? How can we collaborate across industries to protect our modern systems through effective risk management strategies? And in what ways do our institutions need to become more inclusive to better democratize decision-making processes, leading to safer futures for humanity?
“We’re losing 120 calories per person, per day, for every degree of global warming.” That stark data point from a 2025 Nature study signals more than a threat to food security, it points to a growing risk to global financial security. Food system instability exposes markets to cascading shocks: inflation, trade disruption, insurance losses and sovereign credit stress. Yet these risks remain largely unaccounted for in core financial systems.

In a selective history of the evolution of the degrowth movement, his chapter in the Routledge Handbook of Degrowth (2025) offers a collective and subjective reflection revealing tensions between academics, practitioners and activists. Its four co-authors have lived in and with these tensions, analysing practical experiences in the degrowth cooperative Cargonomia (Budapest, Hungary) and the low-tech ecosystem Can Decreix (Cerbère, France). The chapter aims to launch a formal, respectful and significant dialogue between degrowth academics and practitioners. How did an initial public perception of degrowth as activists who experiment-by-doing based in a radical epistemological critique of traditional academia evolve more and more into an academia-dominated movement? We reflect on the movement’s organisation to suggest how deeper collaborative relationships between researchers, activism and practitioners might strengthen degrowth as an academic field, enhance the credibility and robustness of grounded prefigurat

Effective identification and assessment of various energy transition risks are essential for ensuring energy security. This study conducts a systematic review of the literature on energy transition risk assessment, with three principal objectives: ① establishing a standardized risk taxonomy, ② analyzing the characteristics of current assessment methodologies, and ③ identifying the priority research directions. First, energy transition risks are structured into two categories: implementation risks and consequential risks. Subsequently, assessment methodologies are categorized into five methodological groups: the indicator approach, probabilistic risk assessment approach, econometric approach, simulation approach, and hybrid approach.

We report striking discoveries of numerous seafloor seeps of climate-reactive fluid and gases in the coastal Ross Sea, indicating this process may be a common phenomenon in the region. We establish the recent emergence of many of these seep features, based on their discovery in areas routinely surveyed for decades with no previous seep presence. Additionally, we highlight impacts to the local benthic ecosystem correlated to seep presence and discuss potential broader implications. With these discoveries, our understanding of Antarctic seafloor seeps shifts from them being rare phenomenon to seemingly widespread, and an important question is raised about the driver of seep emergence in the region. While the origin and underlying mechanisms of these emerging seep systems remains unknown, similar processes in the paleo-record and the Arctic have been attributed to climate-driven cryospheric change. Such a mechanism may be widespread around the Antarctic Continent, with concerning positive feedbacks that are curr
The doughnut-shaped framework of social and planetary boundaries (the ‘Doughnut’) provides a concise visual assessment of progress towards the goal of meeting the needs of all people within the means of the living planet1,2,3. Here we present a renewed Doughnut framework with a revised set of 35 indicators that monitor trends in social deprivation and ecological overshoot over the 2000–2022 period. Although global gross domestic product (GDP) has more than doubled, our median results show a modest achievement in reducing human deprivation that would have to accelerate fivefold to meet the needs of all people by 2030.
Four key parts of the Earth’s climate system are destabilising, according to a new study with contributions from the Potsdam Institute for Climate Impact Research (PIK). Researchers analysed the interconnections of four major tipping elements: the Greenland ice sheet, the Atlantic meridional overturning circulation (AMOC), the Amazon rainforest and the South American monsoon system. All four show signs of diminished resilience, raising the risk of abrupt and potentially irreversible changes.

Chapter 5 in the Routledge Handbook of Degrowth (2025) sketches the French origins of, and approaches to, décroissance. In France, décroissance emerged early – as part of the long history of debates on the industrialisation of the world and its impacts, and of a shorter history of political ecology over the last half-century. Although inspired by a long genealogy questioning the Western industrial trajectory, the word décroissance really came to the fore in the French protest and intellectual scene in 2002, with a convergence between anti-development and anti-advertising movements. Even if degrowth as a slogan and as a movement only emerged recently, its origins, influences, pioneers, pillars and debates were already very strong in the 1970s. After a long hiatus in the 1980s and 1990s, the term décroissance spread spectacularly, entering the political and activist arena at the beginning of the 21st century, designating a sub-group of political ecologists committed to criticising economic development as the do
