The Expert Group on Antarctic Climate Change and the Environment acts as an umbrella for SCAR activities and produces the yearly update to the ACCE report.

The study of Antarctica and the Southern Ocean and their role in the global Earth system has never been more important as the region is experiencing dramatic changes that have global implications.  The climatic, physical and biological properties of Antarctica and the Southern Ocean are closely coupled to other parts of the global environment by the oceans and the atmosphere.  In 2009, SCAR published the landmark Antarctic Climate Change and the Environment Report.
