More rare events in the Arctic
Presentation by Dr. James E. Overland (NOAA/PMEL)
Twenty years ago, the Arctic was more resilient than now as sea ice was three times thicker than today and provided a buffer against the influence of short-term climate fluctuations. The recent decade has seen an increase in 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 more mobile, coastal erosion, springtime snow loss, permafrost thaw, wildfires, and bottom to top ecosystem reorganizations. While their numbers increase, the distribution of the type, location, and timing of extreme events are less predictable.
