A section of the West Antarctic Ice Sheet has declined to a point that’s irreversible, two groups of NASA scientists reported last week. As NASA’s narration explains below, six glaciers in particular are rapidly melting into the Amundsen Sea, and there are no barriers like mountains or hills to halt this retreat. Scientists point to climate change and warmer ocean temperatures as causes.

The latest sea ice data are out, and they aren't pretty. Here’s the latest:

The sea ice data in particular are drawing a lot of attention because sea ice maintenance affects weather patterns around the globe, melting ice contributes to warmer oceans and rising sea levels, and unusual ice patterns can wreak havoc on the lives of native humans and animals, particularly polar bears, which can drown, and walruses, which can starve.
