Record Temperatures 20-25C Above Norm in far North
The Northwest Territories of Canada had March temperatures above 20C for the first time (hit 21.6C or 71F); breaking norms by 20-25C (normal is below freezing). I discuss a new study from UN Environment that made global news about the inevitability of sharp rises in temperature being locked in. Arctic temperature amplification has mostly been due to albedo declines with reduced sea-ice and land snow cover. Wavy jet streams bring heat (sensible and latent) to the Arctic; Arctic air moved south in a big blob over North America, and ocean mixing brings heat from depth to the surface to melt out ice.
