Last chance to register! Our webinar on permafrost thaw is in 2 days.
Annett Bartsch will show how satellites track permafrost thaw across Arctic lowlands & mountain regions, and what nearly 30 years of data reveal: where it’s accelerating and how unevenly. Secure your spot: tinyurl.com/k6mhk53z

Annett Bartsch has dedicated her career to understanding what's happening with ice beneath the surface. As Science Lead of ESA CCI+ Permafrost, she uses satellite data to track ground temperature changes across Arctic lowlands and mountain regions. Join her webinar: tinyurl.com/k6mhk53z
Logo of the Coordinated Regional Climate Downscaling Experiment (CORDEX). The word "CORDEX" is displayed in large dark blue letters, with the "O" replaced by a green-blue gradient globe. Flowing lines in blue and green extend from the top right. Below, the full name "Coordinated Regional Climate Downscaling Experiment" is written in dark blue.
📢@wcrpclimate.bsky.social's Coordinated Regional Climate Downscaling Experiment (CORDEX) project office will now be hosted by @esa.int and the University of Cape Town. Its work on regional climate downscaling is essential for local adaptation planning. We look forward to strengthening collaboration.
