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
Typical age: 9–11 years
“Can your child explain how climate change is melting polar ice — that Arctic sea ice is shrinking, ice sheets are losing mass, and that melting actually makes more melting happen in a vicious cycle?”
