U021:
Union Session on Relations Among Recent Arctic Environmental Changes and Global Changes





Session ID#: 26747

Session Description:
In recent decades the Arctic environment that are now reaching critical levels. Arctic Ocean circulation, salinity, and temperature have changed and sea ice mass and extent have declined alarmingly. Mass loss of the Greenland ice sheet has accelerated. Now, 2016-2017 has seen record warm winter atmospheric temperatures, a record minimum amount of multiyear sea ice, and record minimum winter sea ice extent, setting the stage in summer 2017 for record minimum sea ice extent. These changes are partly forced by global-scale ocean/atmosphere changes. Conversely, Arctic changes affect global climate by modifying the radiative heat balance, the strength of the global overturning circulation, and the interaction between the ocean and Greenland ice sheet. This special US CLIVAR session will explore recent Arctic environmental changes and specifically their connections to global changes. The session will end with a panel discussion on ongoing and planned science initiative (e.g. CLIVAR, GRISO, NASA OMG).
