Oil prices could jump to $200 per barrel and even higher if the Strait of Hormuz remains near-closed as it is at the moment, Fereidun Fesharaki, Chairman Emeritus of energy consultancy FGE NexantECA, told Bloomberg on Tuesday. Although the oil market is moving on sentiment and U.S. President Donald Trump’s social media posts about the war, the fact is that “every week, 100 million barrels of oil is not going through, and every month, 400 million barrels are not going through,” Fesharaki told Bloomberg Television.
Researchers in Japan have developed a new material that allows solar cells to generate an amount of energy from sunlight that was previously thought impossible. The discovery, made by a team at Kyushu University, involves a special “spin-flip” emitter that can harvest energy from the Sun that is typically lost as heat. The breakthrough overcomes the long-standing limit of conventional solar cells to achieve an energy conversion efficiency of 130 per cent – opening up new possibilities for ultra-efficient solar panels.

We can’t know how long the war in the Middle East will last. Nor can we know who will “win” it, and in which terms. What we know is that the destruction already wreaked on things and people is immense, and it keeps escalating. The longer the war, the bleaker their perspectives in a region already plagued by all sorts of problems, including drought, soil degradation, ecosystem damage, scarce agricultural resources, declining fertility rates, and more.

Anti-authoritarian rallies, taking place in all 50 states plus 16 countries, are expected to be biggest in US history
Thousands of rallies are expected across the U.S. on Saturday as part of the latest “No Kings” protest against the policies of President Donald Trump and his administration. Organizers said more than 3,200 events are planned in all 50 states for what they hope could be the largest single-day nonviolent protest in U.S. history. The two previous No Kings events attracted millions of participants.

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

Models are converging on prediction of an El Nino beginning this year, peaking in early 2027. After overlooking the possibility of an El Nino this year, some reporting is jumping on a “Super El Nino” bandwagon. El Nino strength and frequency are important, especially the issue of whether these are modified by global warming. However, the more important knowledge that needs to be extracted from near-term global warming concerns interpretation of ongoing, extraordinary, acceleration of ocean surface warming. Impacts of this ocean warming include a factor of two greater warming over land, increased extreme precipitation, and poleward movement of subtropical conditions.

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

In one of the most comprehensive empirical studies to date of AI strategic reasoning, Professor Kenneth Payne of King’s College London examined how large language models navigate simulated nuclear crises. Across 21 scenarios, the models displayed sophisticated escalation logic consistent with classical strategic theory – yet nuclear signalling occurred in 95% of games and no model ever chose outright concession. The findings challenge assumptions about AI restraint and offer new tools for defence analysis.

There is mounting experimental evidence that lifetime exposure to increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. Directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. This has the potential to cause a range of adverse health effects.
The Gulf Stream is part of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC is a tipping element and may collapse under changing forcing. However, the role of the Gulf Stream in such a tipping event is unknown. Here, we investigate the link between the AMOC and Gulf Stream using a high-resolution (0. 1°) stand-alone ocean simulation, in which the AMOC collapses under a slowly-increasing freshwater forcing. AMOC weakening gradually shifts the Gulf Stream near Cape Hatteras northward, followed by an abrupt northward displacement of 219 km within 2 years. This rapid shift occurs a few decades before the simulated AMOC collapse. Satellite altimetry shows a significant (1993–2024, p < 0.05) northward Gulf Stream trend near Cape Hatteras, which is also confirmed in subsurface temperature observations (1965–2024, p < 0.01). These findings provide indirect evidence for present-day AMOC weakening and demonstrate that abrupt Gulf Stream shifts can serve as early warning indicator for AMOC tipping.

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

As reported by the Guardian, scientists just published a warning that Earth is approaching a point of no return. A new study in the journal One Earth shows multiple climate systems — the Greenland ice sheet, the West Antarctic ice sheet, boreal permafrost, the Amazon rainforest — are all much closer to collapse than previously thought. “Research shows that several Earth system components may be closer to destabilising than once believed,” the researchers urged. “While the exact risk is uncertain, it is clear that current climate commitments are insufficient.”

A critical step on the path towards climate neutrality, the European Union’s 2040 target calls for a 90-per-cent reduction in emissions. Yet as far-reaching as this goal may seem, its provisions constitute a weakening of Europe’s climate ambitions under the Green Deal. By allowing costly and ineffective CO2 removal and storage technologies as a way of lowering emissions, the target risks deterring direct emission cuts and outsourcing pollution.
US President Donald Trump has announced the reversal of the so-called endangerment finding, a key Obama-era scientific ruling that underpins much of US environmental legislation. As a result of this, experts are predicting various environmental and economic impacts, though the decision by the US Environmental Protection Agency (EPA) is expected to be challenged in the courts from environmental groups.

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.

I know it’s almost impossible to turn your eyes away from the Trump show, but that’s the point. His antics, ever-grosser and more preposterous, are designed to keep him in our minds, to crowd out other issues. His insatiable craving for attention is a global-threat multiplier. You can’t help wondering whether there’s anything he wouldn’t do to dominate the headlines.
In Belem, Brazil’s leader, President Lula da Silva, opened the talks by denouncing obstructionists who “reject scientific evidence and attack institutions.” “They manipulate algorithms, sow hatred and spread fear,” he said, describing a surge in disinformation and propaganda aimed at blocking action to slow climate change. The summit, for the first time, put the issue on the agenda. A coalition of countries and international agencies issued a separate “Declaration on Information Integrity on Climate Change,” calling on governments to address climate disinformation, promote transparency and protect journalists, scientists and environmentalists.

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.

When a series of power outages hit Europe last year, the finger of blame was quickly – and falsely – pointed to an unlikely source: renewables. Blackouts are being used as a political tool to oppose the energy transition. But they can also become an opportunity for open discussions about energy infrastructure – a topic too often reserved only for technical audiences.

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 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.

Children’s developing lungs make them vulnerable to air pollution.
What if the real danger wasn’t the crises ahead… but the established illusion that we can solve them without changing the system that produces said crises? In this uncompromising and deeply eye-opening talk, renowned systems thinker and strategist Arthur Keller challenges one of the most comforting ideas of our time: the belief that “solutions exist” to the great planetary predicaments of our time. Climate action, energy transition, technical innovation… are all crucial, yet they’re somewhat off topic if they remain integrated within a system that inexorably turns nature into waste. Arthur reframes the situation with brutal clarity. Humanity is not facing an ecological crisis: it is nature that’s facing a human crisis. The problematic is no collection of isolated problems to tackle one by one: it is rather the symptom of a civilization operating beyond planetary limits. Decarbonizing energy without transforming the underlying system, he argues, is like treating cancer with painkillers. The disease keeps sprea

“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.

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

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
Climate regime shifts (CRSs), characterized by abrupt and persistent transitions between alternative stable states in the climate system, pose serious threats to ecosystems and human well-being. Understanding the potential drivers of CRSs is crucial, particularly in a warming world where CRSs are becoming more frequent.

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.
Neonicotinoid insecticides are a major driver of pollinator decline. Due to their persistence and mobility in soil, they can contaminate non-target vegetation through runoff or dust, reaching pollinator resources. However, predicting soil contamination is challenging, especially where pesticide use data is lacking. This study assessed the potential of using proxies such as cropping history and landscape structure to predict neonicotinoid content in soils. We analyzed seven neonicotinoids in 86 sites in agricultural landscapes of Belgium.

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

It must be done with care, with binges considered for the long haul. “Overindulging…may be detrimental to your mental health,” warns the doomscrolling subreddit r/Collapse. “Anxiety and depression are common reactions when studying collapse…If you are considering suicide….” (If you are considering suicide: this may end up one of the mantras of the era of modern civilizational crack-up.)

The Environmental Protection Agency is moving forward with approvals for pesticides containing “forever chemicals” as an active ingredient, dismissing concerns about health and environmental impacts raised by some scientists and activists. This month, the agency approved two new pesticides that meet the internationally recognized definition for per- and polyfluoroalkyl substances, also known as PFAS or fluorinated substances, and has announced plans for four additional approvals.

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

As the administration took a victory lap for hammering out a Gaza ceasefire last week, Kushner, Trump’s son-in-law, stood in Tel Aviv’s ‘hostages square’, addressing a feverish crowd that had booed the mention of Israel’s prime minister, Benjamin Netanyahu, and later broke into chants of: “Thank You Trump!”

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

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

A California outfit has used artificial intelligence to design viral genomes before they were then built and tested in a laboratory. Following this, bacteria was then successfully infected with a number of these AI-created viruses, proving that generative models can create functional genetics. "The first generative design of complete genomes." That's what researchers at Stanford University and the Arc Institute in Palo Alto called the results of these experiments. A biologist at NYU Langone Health, Jef Boeke, celebrated the experiment as a substantial step towards AI-designed lifeforms, according to MIT Technology Review. "They saw viruses with new genes, with truncated genes, and even different gene orders and arrangements," Boeke said.

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

President Donald Trump has been sending campaign fundraising emails with the subject line: “I want to try and get to Heaven.” The emails follow recent public remarks regarding Russia’s war on Ukraine, in which he said he was trying to “get to heaven,” comments which gained national attention. Framing his political survival and legal battles as signs of divine purpose, the emails request supporters to donate $15 during a “24-HOUR TRUMP FUNDRAISING BLITZ.”
Conservative leader Kemi Badenoch has described her plan to “maximise extraction” of the UK’s oil and gas from the North Sea as a “common sense” energy policy. Politicians are using language like this increasingly often – calling themselves “pragmatic” on climate change and invoking “common sense”. It sounds reasonable, reassuring, and grownup – the opposite of “hysterical” campaigners or “unrealistic” targets.

Scientists say ‘shocking’ discovery shows rapid cuts in carbon emissions are needed to avoid catastrophic fallout
Several, more recent global warming projections in the coupled model intercomparison project 6 contain extensions beyond year 2100–2300/2500. The Atlantic meridional overturning circulation (AMOC) in these projections shows transitions to extremely weak overturning below the surface mixed layer (<6 Sv; 1 Sv = 106 m3 s−1) in all models forced by a high-emission (SSP585) scenario and sometimes also forced by an intermediate- (SSP245) and low-emission (SSP126) scenario. These extremely weak overturning states are characterised by a shallow maximum overturning at depths less than 200 m and a shutdown of the circulation associated with North Atlantic deep water formation. Northward Atlantic heat transport at 26°N decreases to 20%–40% of the current observed value. Heat release to the atmosphere north of 45°N weakens to less than 20% of its present-day value and in some models completely vanishes, leading to strong cooling in the subpolar North Atlantic and Northwest Europe. In all cases, these transitions to a

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

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

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

Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants. Nonylphenol ethoxylates reach sewage treatment works in substantial quantities where they biodegrade into several by-products including nonylphenol. Due to its physical–chemical characteristics, such as low solubility and high hydrophobicity, nonylphenol accumulates in environmental compartments that are characterised by high organic content, typically sewage sludge and river sediments, where it persists.

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

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.
Societal downfalls loom large in history and popular culture but, for the 99 per cent, collapse often had its upsides
There is rising concern that several parts of the Earth system may abruptly transition to alternative stable states in response to anthropogenic climate and land-use change. Key candidates of such tipping elements include the Greenland Ice Sheet, the Atlantic Meridional Overturning Circulation, the South American monsoon system and the Amazon rainforest. Owing to the complex dynamics and feedbacks between them via oceanic and atmospheric coupling, the levels of anthropogenic forcing at which transitions to alternative states can be expected remain uncertain. Here we demonstrate how such interactions can generate spurious signals and potentially mask genuine signs of destabilization. We further review and present observation-based evidence that the stability of these four tipping elements has declined in recent decades, suggesting that they have moved towards their critical thresholds, which may be crossed within the range of unmitigated anthropogenic warming. Our results call for better monitoring of these ti
