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.

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.

The environmental exposome in heart failure risk and progression Nature Reviews Cardiology, Published online: 26 January 2026; doi:10.1038/s41569-026-01247-1The environmental exposome, which includes pollution, contamination, climate and social determinants of health, is intricately involved in the pathophysiology of heart failure. In this Review, Hahad and colleagues explore the complex relationship between environmental stressors and heart failure, advocating for their inclusion alongside traditional risk factors and highlighting the need for new strategies to address the effects of the exposome on public health.

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.

Trump’s biggest climate rollback stalls over fears it will lose in court Trump officials have delayed finalizing the repeal of the agency’s “endangerment finding” over concerns the proposal is too weak to withstand a court challenge.

Article updates on the repeal of the endangerment finding for CO2. The administration is worried that their case is not strong enough to withstand legal challenges.

virgules et points d'exclamation

Demande au vent assis dans la marge
de souffler entre les lignes
