NEW ANALYSIS: China's CO2 has now been 'flat or falling' for 21 months * Down in 2025 * Still below Mar 2024 * Clean energy wave a key factor If this is China's peak (TBC) it's the climate story of the century so far… www.carbonbrief.org/...

NEW: A newly updated reference manual for U.S. judges that provides answers to scientific and technical questions has eliminated some 90 pages about climate science. It comes as numerous climate cases make their way through state and federal courts.

The science is clear. The stakes are real. AGU condemns the repeal of the EPA Endangerment Finding — a decision that rejects the overwhelming evidence and undermines climate accountability. We will continue to defend science and advocate for evidence-based policy. buff.ly/wX1BQ2t

There are tens of thousands of scientists working in the US whose funding or careers have been damaged, and dozens of them moving to other countires is...not that many. "Just move to somewhere else and do science" is not a serious approach here. There aren't anywhere near enough jobs elsewhere.

Depuis 2019, tous les hivers sont globalement doux en France et cet #hiver2026 ne fera pas exception (sauf énorme surprise). Ce sera le 9ème hiver consécutif avec une T°moy >= 6 °C en moyenne nationale, alors qu'avant 2018, il n'y avait jamais eu plus de 3 hivers d'affilée >= 6 °C (1988, 1989, 1990)

I don't say this often but: I'm so proud to be a climate and environment reporter. We cover an issue that is vitally important to humanity and the natural world. 14 of my climate colleagues at the Post were laid off today and I'm devastated. www.climatecoloredgoggles.com/p/washington...

Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/... And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10.... Paleoclimate evidence generally provides the strongest constraint on high ECS.

When it rains, it now rains more. For those experiencing the flooding in south-west England, it is worth remembering that rainfall in winter has increased by about 25% overall. And, the rainfall has also become more intense: when it rains, it now rains more, increasing the risk of flooding.

Funding cuts to critical research, staff reductions at agencies, political interference & disinformation are eroding public trust in decades of peer-reviewed science. How can we respond to this challenging moment? Here's some inspiration by Allie Cashel from @protectdemocracy.org.

The global warming trend continued in 2025. Each of the past 11 years (2015–2025) has been among the 11 warmest on record. Explore more data from #CopernicusClimate in the Global Climate Highlights 2025. #GCH2025 🔗 climate.copernicus.eu/global-clima... @ecmwf.int

🌡️ 2025 was the third-warmest year on record, with a global average temperature 0.59°C above the 1991–2020 average & 1.47°C above the 1850–1900 pre-industrial level. It was 0.13°C below 2024, the warmest year on record, and only 0.01°C cooler than 2023. @ecmwf.int ⬇️

2025 a été la troisième la plus chaude jamais enregistrée dans le monde et en Europe, selon Copernicus. C’est la première fois qu’une période de trois ans (2023, 2024 et 2025) franchit la barre de 1,5 °C de réchauffement. Les événements extrêmes se sont multipliés www.lemonde.fr/planete/arti...
