Abstract

This background paper is the first of a series of yearly updates to the SCAR Antarctic Climate Change and the Environment (ACCE) Report. It considers two key questions that climate and other environmental scientists are concerned with: The separation of natural climate variability from anthropogenic signals and the Antarctic ice sheet and sea level.

SCAR has formed an ACCE Expert Group that will provide future updates, a summary of which will be provided to CCAMLR.
