Is it true that a 27-year study of Alaska soil temperatures found warming at depth at 100% of monitoring stations, with permafrost regions warming fastest at 0.64 degrees Celsius per decade?

Yes. A peer-reviewed 2026 study synthesizing 43 Alaska weather stations over 1997-2023 reports significant soil warming across all regions, with whole-profile warming averaging 0.64 degrees Celsius per decade in continuous permafrost, the fastest-warming region, and warming not slowed by depth.
