European scientists warn of consequences for weather patterns, the global climate and marine life

juin 2026

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress
Extreme hitte vormt een van de meest onderschatte bedreigingen voor de economische ontwikkeling wereldwijd. Vooral vrouwen die dichtbij de armoedegrens leven worden zwaar getroffen, stelt een nieuw rapport dat op de London Climate Action Week is gepresenteerd.
Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance
Climate scientists warn of unprecedented Antarctic heatwave, with temperatures 20C above normal. Loss of sea ice threatens marine life and penguins.
The system of ocean current that moves heat in the Atlantic Ocean plays a key role in regulating climate. Today’s monitoring of it may be discontinued...
Scientists know how to alter our atmosphere to try and fix climate change, but doing so could bring other potential unintended impacts
Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes. Figures in this post and our recent papers are continually updated on our website.[1] We are also now on Substack[2].
Vagues de chaleur marines en hausse, fonte du budget carbone... Ces indicateurs qui explosent témoignent du rythme sans précédent atteint par le réchauffement planétaire, estiment 73 chercheurs dans un rapport publié le 11 juin.
- Artificial intelligence could pose a "more urgent" threat to humanity than climate change, AI pioneer Geoffrey Hinton told Reuters in an interview on Friday. Geoffrey Hinton, widely known as one of the "godfathers of AI", recently announced he had quit Alphabet, opens new tab after a decade at the firm, saying he wanted to speak out on the risks of the technology without it affecting his former employer.
Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says
The Global Justice Report offers a hopeful bargain: tax extreme wealth and replace consumer excess with social and economic security for all

When major new climate change scenarios are released, there’s always strong interest. These scenarios lay out what our future climate will look like, depending on how fast we act to cut emissions.
Investment firms have put over $100 million into developing risky technologies that could cool the planet with unknown side effects.
Exclusive: Commission says alert would trigger coordinated international response that could help avoid millions dying. The climate crisis should be declared a global public health emergency by the World Health Organization, or millions more people will die unnecessarily, leading international experts have said. The independent pan-European commission on climate and health, which was convened by the WHO, concluded the climate crisis was such a worldwide threat to health that the WHO should declare it “a public health emergency of international concern” (Pheic).
Op 29 april publiceerden de Copernicus Climate Change Service (C3S) en de Wereld Meteorologische Organisatie (WMO) hun jaarlijkse rapport “European State of the Climate 2025”. Deze gedetailleerde analyse van het Europese klimaat omvat een brede waaier aan klimaatvariabelen, van de jaarlijkse temperatuur, hitte- en koudestress tot zonneschijnduur en bewolking, van bosbranden tot gletsjers en nog veel meer.
Climatologists say a particularly powerful weather pattern could amplify wildfire risk, heatwaves and flooding worldwide as global temperatures continue to rise
Patrick Pester is the trending news writer at Live Science. His work has appeared on other science websites, such as BBC Science Focus and Scientific American. Patrick retrained as a journalist after spending his early career working in zoos and wildlife conservation. He was awarded the Master's Excellence Scholarship to study at Cardiff University where he completed a master's degree in international journalism. He also has a second master's degree in biodiversity, evolution and conservation in action from Middlesex University London. When he isn't writing news, Patrick investigates the sale of human remains.
A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.
The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.

There is reason to expect that global temperatures will continue to increase over the remainder of the year, as a strong El Niño event is expected
Environment News: UNITED NATIONS: Vanuatu will renew its climate justice fight at the United Nations General Assembly with a draft resolution that was watered down afte.
Climate models show considerable discrepancies in their future projections around the Atlantic, mainly due to uncertainties in the fate of the Atlantic Meridional Overturning Circulation (AMOC). Climate models suggest a reduction in AMOC strength of 32 ± 37% by 2100 (90% probability, Shared Socioeconomic Pathways 2-4.5 scenario, Coupled Model Intercomparison Project Phase 6). To refine this estimate and reduce its uncertainty, we use four different observational constraint methods. The best one, which provides the lowest leave-one-out error, integrates a large set of observable variables using ridge-regularized linear regression—a method unusual in climate science. It gives an estimate of the AMOC slowdown of 51 ± 8% (90% probability), i.e., a weakening ∼ 60% stronger than suggested by the multimodel mean. This refinement mainly results from correcting a bias in South Atlantic surface salinity, consistent with recent studies emphasizing its role in the proximity to an AMOC tipping point. This more substantial
Wildfires used to die down and even stop at night with cooler temperatures and increased humidity. But a study released Friday says climate change is making burning weather more around the clock in North America because night is becoming warmer and drier. Canadian fire scientists say potential burning hours for fires have increased 36% in the last 50 years. California now has about 550 more fire-friendly hours a year than it did in the 1970s. North American summer nights are warming faster than days, evening relief is evaporating for forests and that means the area of land burned is soaring.
Closed-door talks over the World Bank’s climate agenda have stalled, as the US pushes to scrap green targets and expand support for fossil fuels
The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding “very concerning” as a collapse would have catastrophic consequences for Europe, Africa and the Americas.
Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older people
A team including scientists, Indigenous people and conservationists point to the ecosystem connecting Yellowstone and the Yukon as an example of a region where humans and nature are flourishing together.
Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation and adaptation actions). This paper describes the scenario framework for ScenarioMIP as part of CMIP7. The design process has involved various rounds of interaction with the research community and user groups at large. The proposal covers a set of scenarios exploring high levels of climate change (to explore high-end climate risks), medium levels of climate change (anchored to current policy), and low levels of climate change (aligned with current international agreements). These scenarios follow very different trajectories in terms of emissions, with some likely to experience peaks and subsequent declines in greenhouse gas concentrations in this century. An important innovation is that most scenarios are intended to be run, if possible, in emission-driven mode, providing a better representation of the Earth system uncert
In a Swiss forest lab, scientists tracked how beech and oak leaves cool themselves and pinpointed the moment heat and drought push them past their limits.
Using a field experiment, we measured the heat tolerance of insects across many different groups. This is important because most previous studies either combine inconsistent datasets or focus on a single species. Our goal was to understand how entire insect communities respond to heat. We looked at a large variety of insects, such as flies, bees, beetles, butterflies and grasshoppers, to name just a few. We found that many are likely to face dangerous levels of heat stress. This was true even under conservative assumptions, including the possibility that species move into cooler habitats.

Trump a lancé une attaque sans précédent contre l’environnement. Où est la riposte ? Les climatosceptiques s’attendaient à plus de résistance face à l’offensive en faveur des énergies fossiles. Mais les démocrates, les milliardaires et les militants sont restés silencieux. ...
As climate change accelerates, its effects are being felt in every corner of the world. A comprehensive global index developed by researchers at the University of Notre Dame has assessed the climate vulnerability and adaptive readiness of nearly 200 countries, revealing stark and troubling disparities between the world’s wealthiest and most impoverished nations.
Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño
What is currently happening in Brussels under the guise of regulatory simplification is being presented as something technical and logical. Less regulatory pressure, more competitiveness. A series of so-called omnibus bills are intended to streamline legislation. Reporting obligations are being limited and reassessments of raw materials postponed. It sounds like administrative efficiency. In Washington, things are moving even faster: Trump is dismantling the basis for climate laws while the world continues to warm up. The framing is the same: rules slow down businesses, and a slowed-down business community makes us poor. But that reasoning assumes something that is not true: that everyone wants the same thing from the market.

A recent UK national security assessment on biodiversity and ecosystem collapse made headlines, not for its dire warnings, but for its omissions. It's part of a larger trend of governments keeping climate security reports from the public.
Even as weather extremes worsen, the voices calling for the rolling back of environmental rules have grown louder and more influential
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.
Welcome to the Global Climate Highlights 2025 report, compiled by the Copernicus Climate Change Service (C3S). The Global Climate Highlights 2025 report provides authoritative climate data and concise insight on a global scale about 2025's climate conditions, covering surface and sea surface temperature, heat stress, sea ice extent in the Arctic and Antarctic, among others.
Three major Defence Agencies are quietly admitting what most still refuse to face: climate breakdown is coming for our food, and the cracks are already spreading. While the wealthy cling to logistics and illusion, the real defence strategy is soil and local growers who refuse to let their communities starve.
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.
Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world
Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware
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.
By the end of this century, parts of Africa could face heatwaves for 250-300 days a year, which will make it difficult for people to survive.
Climate change is making it challenging to identify future host cities.
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.

Climate change could lead to half a million more deaths from malaria in Africa over the next 25 years, according to new research.
With warming set to pass the critical 1.5-degree limit, scientists are warning that the world is on course to trigger tipping points that would lead to cascading consequences — from the melting of ice sheets to the death of the Amazon rainforest — that could not be reversed.
The 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.

As climate and geopolitics shocks bite, countries are rebuilding food buffers. The UK clings to neoliberal ideas while households pay the price
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.
The world's oceans absorbed a record amount of heat in 2025, an international team of scientists said Friday, further priming conditions for sea level rise, violent storms, and coral death.

Legal action has brought important decisions, from the scrapping of fossil fuel plants to revised climate plans
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.
The activist and author of Here Comes the Sun discusses rapid advances in solar and wind power and how the US ceded leadership in the sector to its main rival
From floods to droughts, erratic weather patterns are affecting food security, with crop yields projected to fall if changes are not made
Since 2010, the Environmental Protection Agency (EPA) has required large industrial facilities to report their greenhouse gas emissions. The data, which the EPA’s Greenhouse Gas Reporting Program has been collecting since 2011, is essential in efforts to reduce emissions and provides vital information to the public about climate pollution from the largest U.S. polluters. However, the Trump EPA has proposed to put an end to greenhouse gas reporting by major polluters. This move is consistent with the Trump administration’s intent to make climate denial an official U.S. policy and restricts the public from the right to know. Subsequently, it will deprive communities from having access to a critical tool for holding pollutants accountable.
Real skeptics study the evidence and ask questions, rather than taking political dogma on faith. Experiencing disasters can open more eyes to the risks.
Rob Hopkins has spent the past decades exploring one question: what if we could fall in love with the future? As co-founder of Transition Network and Transition Town Totnes, and author of four books, he travels the world helping communities cultivate imagination, longing and possibility. He believes that the transition we so urgently need depends on one thing above all: imagination.

Exclusive: UCL scientists find large swathes of southern Europe are drying up, with ‘far-reaching’ implications
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
Budgets are now climate policy. But mainstream media hasn’t caught up.
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.
The UK has announced much harsher rules for asylum seekers including the prospect of more deportations for those whose applications fail. The US is trebling the size of its deportation force. The EU is doubling its border budgets. And in the coming decades, hundreds of millions of people might be displaced by ecological changes.
Exclusive interview with ex-US vice-president at Cop30 also reveals his hope around much-maligned climate summit
Decision by international court of justice hailed as a gamechanger for climate justice and accountability

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.
Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30
The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.
