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.”

Le réchauffement a dépassé 1,5°C durant douze mois, et a peut-être déjà passé définitivement ce seuil de sécurité. Il a accéléré et a progressé dernièrement à 0,31°C par décennie, augmentant le ris…

Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware

The world endured its costliest wildfire on record in 2025, its sixth-deadliest heat wave, and four floods or storms that caused at least 1,000 deaths.

Les chiffres sont tombés mercredi, et ils sonnent comme un verdict sans appel. L’observatoire européen Copernicus et l’institut américain Berkeley Earth ont confirmé simultanément ce que de nombreux climatologues redoutaient : pour la première fois dans l’histoire des mesures, la température moyenne mondiale sur trois années consécutives dépasse de 1,5°C le niveau préindustriel. Cette limite, inscrite comme objectif le plus ambitieux de l’accord de Paris en 2015, n’était pas censée être franchie avant plusieurs décennies. Elle vient de céder en moins de trois ans.

Satellite analysis warns that widespread land subsidence threatens 1.6 billion people by 2040, with 86% of the at-risk population concentrated in Asia

L'année 2025 a été la troisième année la plus chaude jamais enregistrée dans le monde, ont annoncé mercredi l'observatoire européen Copernicus et l'institut américain Berkeley Earth, pour qui 2026 devrait rester à des niveaux historiquement hauts. Le thermomètre mondial affiche depuis trois ans des niveaux jamais vus à l'échelle de l'humanité, avec une moyenne sur la période supérieure de 1,5°C au niveau préindustriel (1850-1900), note Copernicus dans son bilan annuel. "La hausse brutale enregistrée entre 2023 et 2025 a été extrême et suggère une accélération du rythme du réchauffement climatique", estiment séparément les scientifiques de Berkeley Earth, aux Etats-Unis.

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.

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.

Around 56 million years ago, Earth suddenly got much hotter. Over about 5,000 years, the amount of carbon in the atmosphere drastically increased and global temperatures shot up by some 6°C.

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.

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.

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.

Earth’s average temperature rose more than 1.5°C above pre-industrial levels in 2024 for the first time – a critical threshold in the climate crisis. At the same time, major armed conflicts continue to rage in Ukraine, Gaza, Sudan and elsewhere. What should be increasingly clear is that war now needs to be understood as unfolding in the shadow of climate breakdown. The relationship between war and climate change is complex. But here are three reasons why the climate crisis must reshape how we think about war.

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

New research reveals Earth's natural carbon sink nearly collapsed in 2024, absorbing almost zero human CO₂ emissions.

The world is losing fresh water at an unprecedented rate, two decades' worth of satellite data has revealed. Measurements from NASA's twin GRACE satellites and GRACE follow-on missions have shown that since 2002, the amount of land suffering from water loss has been increasing year on year by twice the area of the state of California. That includes the loss of water from surface reservoirs such as lakes and rivers and underground aquifers, which are an important source of drinking water around the globe.

As civilization advanced, humans developed tools that allowed us to shield ourselves from the natural cycles that once defined our lives. Fire helped us escape the cold. Irrigation let us shape landscapes around our needs. Walls and weapons kept predators at bay. Over time, these inventions accumulated into infrastructure, then ideology. The more protected we became, the more separated we felt...

2024 was the hottest year on record [1], with global temperatures exceeding 1.5 °C above preindustrial climate conditions for the first time and records broken across large parts of Earth’s surface. Among the widespread impacts of exceptional heat, rising food prices are beginning to play a prominent role in public perception, now the second most frequently cited impact of climate change experienced globally, following only extreme heat itself [2]. Recent econometric analysis confirms that abnormally high temperatures directly cause higher food prices, as impacts on agricultural production [3] translate into supply shortages and food price inflation [4, 5]. These analyses track changes in overall price aggregates which are typically slow-moving, but specific food goods can also experience much stronger short-term price spikes in response to extreme heat.

For the last 80 years, Thwaites has been losing more water through melting than it’s been gaining in snow.Half a metre of sea-level rise would submerge large parts of Asia’s coastal cities including Manila and Bangkok, as well as sizeable chunks of the Netherlands and the east of England. It’s also half of the sea-level rise needed to begin flooding Manhattan.

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

Un réchauffement climatique d’au moins +1,5°C est désormais inéluctable, concluent des scientifiques dans un rapport publié ce jeudi, qui vise à dresser un état des lieux de la santé de la planète.

In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets (published at https://doi.org/10.5281/zenodo.15639576; Smith et al., 2025a) to produce updated estimates for key indicators of the state of the climate system: net emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activities, the remaining carbon budget, and estimates of global temperature extremes. This year, we additionally include indicators for sea-level rise and land precipitation change. We follow methods as closely as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One report.

An international group of researchers has produced a third update to key indicators of the state of the climate system set out in the IPCC AR6 assessment, building on previous editions in 2023 and 2024. Forster et al. (2025) assess emissions, concentrations, temperatures, energy transfers, radiation balances, and the role of human activity and conclude that, while natural climate variability also played a role, the record observed temperatures in 2024 were dominated by human activity and the remaining carbon budget for 1.5° C is smaller than ever.

Le seuil de 1,5 °C de réchauffement planétaire sera dépassé sur plusieurs années, alerte un consortium international de scientifiques. Problème : le budget carbone pour le limiter sera bientôt épuisé.

Recent simulations using the Community Earth System Model (CESM) indicate that a tipping event of the Atlantic Meridional Overturning Circulation (AMOC) would cause Europe to cool by several degrees. This AMOC tipping event was found under constant pre-industrial greenhouse gas forcing, while global warming likely limits this AMOC-induced cooling response. Here, we quantify the European temperature responses under different AMOC regimes and climate change scenarios. A strongly reduced AMOC state and intermediate global warming (C, Representative Concentration Pathway 4.5) has a profound cooling effect on Northwestern Europe with more intense cold extremes. The largest temperature responses are found during the winter months and these responses are strongly influenced by the North Atlantic sea-ice extent. Enhanced North Atlantic storm track activity under an AMOC collapse results in substantially larger day-to-day temperature fluctuations. We conclude that the (far) future European temperatures are dependent o

Hidden in every tenth of a degree of extra warmth are hair-trigger switches built into Earth systems that are critical for all life.

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate

The Earth had its second-warmest April in NOAA's 176-year period of record. The 10 warmest Aprils on record have occurred since 2010.

Earth’s albedo (reflectivity) declined over the 25 years of precise satellite data, with the decline so large that this change must be mainly reduced reflection of sunlight by clouds. Part of the cloud change is caused by reduction of human-made atmospheric aerosols, which act as condensation nuclei for cloud formation, but most of the cloud change is cloud feedback that occurs with global warming. The observed albedo change proves that clouds provide a large, amplifying, climate feedback. This large cloud feedback confirms high climate sensitivity, consistent with paleoclimate data and with the rate of global warming in the past century.

Have you ever thought about what would happen if all life in the ocean disappeared? A recent study explores this extreme scenario to understand how ocean biology shapes the past, present, and future climate. The ocean plays a critical role in regulating Earth's climate. It is a massive carbon store that absorbs about 25% of human-caused emissions and thus helps maintain a relatively low CO2 level in the atmosphere. But what would happen if all marine life—from the tiniest plankton to the largest whales—disappeared? A recent study delves into this extreme scenario to uncover the crucial role that ocean biology plays in mitigating climate change.

2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees Celsius above the preindustrial level, another record.A team led by the Alfred Wegener Institute puts forward a possible explanation for the rise in global mean temperature: our planet has become less reflective because certain types of clouds have declined. The work is published in the journal Science.

The planet is edging close to irreversible change, according to the most comprehensive probability analysis yet of climate “tipping points.”

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 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

An international group of scientists, led by King's College London, has revealed how continued global warming will lead to more parts of the planet becoming too hot for the human body over the coming decades. the amount of landmass on our planet that would be too hot for even healthy young humans (18 to 60-year-olds) to keep a safe core body temperature will approximately triple (to 6%)—an area almost the size of the US—if global warming reaches 2°C above the preindustrial average.

2024 was the warmest year on Earth since direct observations began, and recent warming appears to be moving faster than expected.

Global warming is moving faster than the best models can keep a handle on.

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says

Understanding how global mean surface temperature (GMST) has varied over the past half-billion years, a time in which evolutionary patterns of flora and fauna have had such an important influence on the evolution of climate, is essential for understanding the processes driving climate over that interval. Judd et al. present a record of GMST over the past 485 million years that they constructed by combining proxy data with climate modeling (see the Perspective by Mills). They found that GMST varied over a range from 11° to 36°C, with an “apparent” climate sensitivity of ∼8°C, about two to three times what it is today. —Jesse Smith

Juristen van ClientEarth hebben, samen met 14 ngo's, nieuwe juridische stappen ondernomen tegen INEOS, nu de petrochemiereus zijn plannen doorzet om Europa's grootste plasticproject te bouwen. De milieuorganisaties hebben vandaag een rechtszaak aangespannen tegen de Vlaamse overheid. Deze zaak markeert een nieuwe fase in de langdurige juridische strijd van de groep milieuorganisaties tegen 'Project One' van INEOS.

Even recapituleren. Op zondag 7 jan 2024 kreeg Ineos – na een verrassend positief advies van ANB – zijn huidige vergunning van de Vlaamse Regering. De vorige was onderuit gehaald op grond van de beroepsprocedure die de provincie Noord-Brabant had aangespannen. VlaReg werd toen door de Raad voor Vergunningenbetwistingen op de vingers getikt voor haar lossepolswerk aangaande de verwachte stikstofdepositie van Project One voorbij de Nederlandse grens. En al stond het in de sterren geschreven dat zowel de provincie Noord-Brabant als de provincie Zeeland opnieuw beroep zouden aantekenen en dat ook Client Earth opnieuw met een beroep ten gronde zou komen, toch startte Ineos op 8 januari full speed de constructiewerken in Lillo. Evident met de bedoeling om de weg van de voldongen feiten te kiezen en om de beroepsprocedures in snelheid te pakken.

September 2023 smashed the prior global temperature record. Hand-wringing about the magnitude of the temperature jump in September is not inappropriate, but it is more important to investigate the role of aerosol climate forcing – which we chose to leave unmeasured – in global climate change. Global temperature during the current El Nino provides a potential indirect assessment of change of the aerosol forcing. Global temperature in the current El Nino, to date, implies a strong acceleration of global warming for which the most likely explanation is a decrease of human-made aerosols as a result of reductions in China and from ship emissions. The current El Nino will probably be weaker than the 1997-98 and 2015-16 El Ninos, making current warming even more significant. The current near-maximum solar irradiance adds a small amount to the major “forcing” mechanisms (GHGs, aerosols, and El Nino), but with no long-term effect. More important, the long dormant Southern Hemisphere polar amplification is probably com

This planetary boundaries framework update finds that six of the nine boundaries are transgressed, suggesting that Earth is now well outside of the safe operating space for humanity. Ocean acidification is close to being breached, while aerosol loading regionally exceeds the boundary. Stratospheric ozone levels have slightly recovered. The transgression level has increased for all boundaries earlier identified as overstepped. As primary production drives Earth system biosphere functions, human appropriation of net primary production is proposed as a control variable for functional biosphere integrity. This boundary is also transgressed. Earth system modeling of different levels of the transgression of the climate and land system change boundaries illustrates that these anthropogenic impacts on Earth system must be considered in a systemic context.
