Arctic Report Card 2019

Arctic Report Card 2019 (NOAA, Dec 2019, 100p, 3p exec summary)

Report of the U.S. National Oceanic and Atmospheric Administration.  Published annually since 2006, these essays involve 81 scientists from 12 countries reporting on the acceleration of ice melting in a region where temperature changes are twice as high as elsewhere.  Topics include rising air temperature, melting of the Greenland ice sheet, terrestrial snow cover, the rising threat of marine microplastics (higher than all other ocean basins in the world), the increase in river discharge, harmful toxic algal blooms, and how Arctic warming affects the jet stream by allowing cold Arctic air to move south.

“Arctic ecosystems and communities are increasingly at risk due to continued warming and declining sea ice. The Arctic marine ecosystem and the communities that depend upon it continue to experience unprecedented changes as a result of warming air temperatures, declining sea ice, and warming waters. Arctic Report Card 2019 draws particular attention to the Bering Sea region, where declining winter sea ice exemplifies the potential for sudden and extreme change. Indigenous Elders from the Bering Sea region offer their experiences of living at the forefront of climate change.”
