Floating sea ice off the Antarctic Peninsula

Here we see “the smooth edge of a floating sea of ice” off the western coast of the Antarctic Peninsula on Nov. 10, 2010. It’s not just water levels that are being influenced by the decline of sea ice in the Arctic. Experts note that warmer ocean waters create more waves that “eat away” at the coastline of the continent, thawing out the permafrost and leaving the ground more vulnerable to erosion.
