# Climate Change at the Poles

Understand how climate change is affecting polar regions — Arctic sea ice is shrinking dramatically (losing about 13% per decade since 1979), the Greenland and Antarctic ice sheets are losing mass and contributing to sea level rise, permafrost is thawing and releasing methane (a powerful greenhouse gas), and these changes create positive feedback loops where melting leads to more warming which leads to more melting
