The “Wet-Gets-Wetter” Response to Climate Change Does Not Always Apply

by Donald Wuebbles 4 March 20263 March 2026

While the precipitation response to a warming climate is often stated as the “wet gets wetter,” this response does not apply to east-west overturning circulations like the Pacific Walker circulation.

Future Hotspots of Hazardous Rivers in the Atmosphere

by Thomas Stocker 3 March 20263 March 2026

Atmospheric rivers can produce heavy precipitation and associated hazards worldwide. A new study identifies regions where these hazards have already, and will further, increase with global heating.
