HE012:
The Connections Among Changes in the Arctic Ocean, World Ocean, and Climate


Session ID#: 28558

Session Description:
The Arctic Ocean has changed substantially in recent decades. Circulation, salinity, and temperature have changed and the sea ice has shown alarming declines. Connections between these changes and global and regional indices of atmospheric variability have been suggested. Conversely, Arctic Ocean changes are thought to affect global climate by modifying the global radiative heat balance through ice-albedo feedback and by impacting the strength of the global overturning circulation. Ocean-ice sheet interaction is thought to be important in the accelerated mass loss of the Greenland ice sheet. Discussion of the links between Arctic Ocean changes and global environmental changes has arguably never been timelier. The Winter 2016-2017 has seen record warm winter atmospheric temperatures, a record minimum amount of multiyear sea ice, and record minimum winter sea ice extent. These record extremes set the conditions for a massive sea ice retreat in summer 2017. This special US CLIVAR session will examine the connections among recent changes in the Arctic Ocean, the sub-Arctic seas, global ocean, ice sheets, and global climate. A short panel discussion will follow at the end of the session.
