Visualisation of the Arctic sea ice extent in millions of square kilometers from 1979 - 2016.
Since satellites began regularly measuring Arctic sea ice in 1979, it has declined sharply in extent and thickness. Much of the ice that’s there in winter is thin stuff that doesn’t survive the summer. The loss of ice is affecting the entire Arctic ecosystem, from plankton to polar bears. And some scientists think that, by altering the jet stream, it’s affecting weather—and people—around the Northern Hemisphere. (National Geographic)
