WHAT'S ALARMING

The mean temperature rise in the Arctic region, as measured from the period 1979 through 2017, is twice the global mean temperature rise over the same period. This increase correlates with a significant reduction in Arctic sea ice extent over this period, especially during the summer. Arctic sea ice cover varies over the course of a year and can be two or three times greater at end of winter (shown as March on the graph) vs end of summer (shown as September on the graph).*

“Arctic air temperatures for the past five years (2014-18) have exceeded all previous records since 1900….In 2018 Arctic sea ice remained younger, thinner and covered less area than in the past. The 12 lowest extents in the satellite record have occurred in the last 12 years.”**
