"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.

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...
