The movie discusses decreasing sea ice in the Arctic and how it will affect climate and wildlife. Is it really that important?
WALT: Arctic sea ice is something NSIDC watches carefully, especially because of its effect on global climate. Sea ice helps regulate climate because it acts like a mirror, deflecting incoming solar energy and helping to balance the Earth’s temperatures. As the sea ice disappears, dark ocean water is exposed to the sun’s energy, and the Arctic’s ability to cool our planet also disappears. To learn more about the recent, record-breaking disappearance of sea ice, see NSIDC’s Sea Ice Decline Intensifies press release. To learn more about sea ice, its role in climate, and the animals and people that depend on it for survival, see All About Sea Ice.
