UN body that assesses and synthesizes global climate science, producing periodic reports used to guide international climate policy.
Caroline Needell's team found the tallest glacier cliffs retreating faster than models predict, yet none showed unstable retreat in satellite data. That moves the sea-level question to whether faster flow can thin the cliffs before they fail.

Virginia Tech modelers ran 90 synthetic storms against 2050 sea levels and found the Chesapeake Bay damps storm surge less than it does today. The size of that loss is worded in a way that supports two readings.
Reality
A group led by Saudi Arabia and Russia, including India and China, is pressing the IPCC to move its seventh report to 2029, the Guardian reported. The report was timed for the Cop33 summit in 2028, so a slip would put it after the meeting.

Benjamin Santer's team argues more than 30 years of fingerprint research make the human-warming case stronger than in 2009. Their Earth's Future review answers a July 2025 Department of Energy report that questioned the science behind the EPA's Endangerment Finding.

Nearly three years of debate have left the IPCC's 195 member states without publication dates for the next assessment. Under the chairs' proposal, approval would come about two months before the November 2028 Paris stocktake.
Reality
Vrije Universiteit Brussel researchers digitized weather sheets from 37 DRC stations and found hot days nearly doubled between the 1960s and 1980s. The Earth System Dynamics paper is the first to document hot-extreme changes in the basin since the 1960s, its authors say.

AmazonFACE will raise CO2 over a patch of Amazon forest from about 420 to 620 ppm in a decade-long experiment due to start within months. Three treated rings and three controls will test whether the extra carbon stays in the trees.
Reality
Researchers led by the University of Twente conclude in a KIN-commissioned report that no available carbon removal technology is ready for Dutch scale-up. They want rules on land, water, energy and fair burden-sharing in place before any national push toward deployment.
Reality
EHU researchers scored heat-wave vulnerability for every building and open space in Bilbao, Madrid and Cáceres and found hot spots within each city. The team argues that adaptation money should follow the maps, down to which buildings get renovated first.
Reality
EU-funded FAIR2Adapt has backed a new Climate Connectivity Taxonomy release linking related adaptation and disaster-risk terms across five platforms. The links are meant to let someone searching in one community's language reach work written in the other's.
Reality
Garhwal University researchers say the Himalayan monal is changing its call pitch in a noisy Kedarnath valley, in one of two studies run over five years. Lead researcher Rajeev Lochan offers the bird as a warning sign for other mountain species, a case the studies can raise but cannot test, since as reported both measure only the monal.
Reality
Researchers at King's College London and Imperial College London pooled 423 studies and found most of 23 ecosystem benefits rise steadily with diversity. Species appear to stand in for one another less than ecologists assumed, so even small losses tend to cut what ecosystems provide.
Reality
South African researchers reviewed 128 field studies of climate impacts on Mediterranean-type plant communities and found 9% came from the Global South. That limits how far responses seen in California or the Mediterranean Basin can be carried to the Cape.
Reality
Contiguous U.S. temperatures averaged 57.98 degrees F from January to August 2026, the hottest such stretch since records began in 1895, NOAA data show. Only a cooler-than-normal fall would keep 2026 from an annual record, Zeke Hausfather says.
Reality
Carbon Impacts Tracer, a new open-source tool, links Woodside's Browse gas project to an extra week of dangerous heat a year for almost 200,000 people. The figure puts a count on harm that project backers have long called too small to trace to any one project.
Reality
UNEP now accepts the overshoot and describes a way back to 1.5C by 2100 that needs global emissions halved by 2035 and then removal running at a scale one outside researcher puts at 100,000 times today's.

A paper in Environmental Research Letters estimates that permafrost, wildfire, wetland and inland-water emissions amplify human-caused warming by 20 to 30 percent, though at one standard deviation the low-emissions case still runs from zero to 0.4 C.

A Yale-led team writing in Nature argues that crushed limestone spread on farmland across 41 percent of the contiguous United States removes more CO2 than it releases, because the acid it neutralises would have released CO2 anyway.

The co-leads of July's Geneva dialogue want models tested independently before release and incidents reported after it. Their list of things due by May is an evidence assessment, an agenda item and one cross-border sandbox pilot.

Six years of data from the Bangladesh Agricultural University Dairy Farm put milk at 5.18 kilograms of carbon per kilogram, with the cows' own digestion accounting for 48% of everything counted inside the farm gate.
