Arctic Death Spiral Update: What Happens In The Arctic Affects Weather Everywhere Else

"This was the hottest four-month start (January to April) of any year on record, according to newly-released satellite data. The Arctic continues its multi-month trend of off-the-charts warmth. So it’s no surprise that Arctic sea ice continues to melt at a record pace. New research, however, finds that warming-driven Arctic sea ice loss causes high-pressure systems to get stuck in places like Greenland, leading to accelerated melt of the land-locked ice that drives sea level rise worldwide. Let’s start with the University of Alabama at Huntsville (UAH) satellite data, which show that the lowest part of the atmosphere (the lower troposphere) was an impressive 1.3°F (0.71°C) above the historical (1981-2010) average — a baseline that is itself 0.8°F (0.45°C) hotter than pre-industrial levels."
