It has long been known to play a key part in the global climate system, but the difficulty and expense of close monitoring have meant that scientists have only in recent years been able to make detailed assessments. The authors of the report, billed as the first comprehensive study of ecosystems and societies in the region, also warned that people living in and near the Arctic would be badly affected , and called for communities to be provided with equipment and taught new skills to survive.
