"Science is being destroyed across many agencies" say federal researchers. For my latest @nature.com piece, I spoke to 19 different scientists across EPA, NOAA, NIH, NASA, and USGS to document how science is being dismantled across US federal agencies.

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope. According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

The economic case for methane action is clear. - Global methane abatement yields large net global economic benefits. - The benefit-cost ratio of methane action is at least 3—rising to more than 6 when health cobenefits are included. www.science.org/doi/10.1126/...

L'ouragan #Melissa a incurvé sa trajectoire vers la #Jamaïque, à une vitesse toujours lente. A la dernière actualisation du NHC, c'est toujours un ouragan de catégorie 5, avec des vents soutenus de 150 kt et une pression au centre de 901 hPa.

A 10am EDT update from the National Hurricane Center now puts Melissa's sustained winds at 185 mph. Full text: www.nhc.noaa.gov/text/refresh...?

La perturbation automnale active d'hier a généreusement arrosé l'ouest de la Corse. Hier il est tombé 52 mm à Ajaccio ; ajoutés aux 24 mm du 16 octobre, cela fait plus de pluie en une semaine que les 4 mois et demi de mai à mi octobre.

En octobre il n'a jamais fait plus de 20 °C à #Paris et c'est exceptionnel. Malgré une relative douceur en ce début de semaine il est probable que le maximum du mois d'octobre au Parc Montsouris soit derrière nous avec 20.0 °C le 1er. Soit la plus basse valeur en la matière depuis 1998 (19.1°C).

Record warm conditions continue in the northernmost portions of the #Arctic Ocean, near the North Pole. This anomalous warmth is forecast to continue over the next week or so too. More graphics: zacklabe.com/arctic-tempe...

Susan Crawford on California's burgeoning home insurance crisis: "As of June 2025, the FAIR Plan is exposed to $650 billion in claims—a nearly threefold increase since 2021, the last time a rate change went into effect. It appears to have about $1.5 billion in cash on hand."
