Abstract

The recent decade has seen Arctic extreme events in climate and ecosystems including events beyond previous records. Such new extremes include Greenland ice mass loss, sea ice as thin and mobile, coastal erosion, springtime snow loss, permafrost thaw, wildfires, and bottom to top ecosystem reorganizations, a consilience of change. One cause for such new events is due to natural interannual variability in a wavy tropospheric jet stream and polar vortex displacements, interacting with ongoing Arctic changes. The Bering Sea in 2018 and 2019 were examples. Changes in frequency of extreme climate/weather events combine with the life history of Arctic species to cause potential major impacts.
