Ice on the edge of survival: Warming is changing the Arctic

The Arctic is warming three times faster than the rest of the Earth and it's on the knife edge of survival

While conducting research in Greenland, ice scientist Twila Moon was struck this summer by what climate change has doomed Earth to lose and what could still be saved.

The Arctic is warming three times faster than the rest of the planet and is on such a knife’s edge of survival that the U.N. climate negotiations underway in Scotland this week could make the difference between ice and water at the top of the world in the same way that a couple of tenths of a degree matter around the freezing mark, scientists say.

Arctic ice sheets and glaciers are shrinking, with some glaciers already gone. Permafrost, the icy soil that traps the potent greenhouse gas methane, is thawing. Wildfires have broken out in the Arctic. Siberia even hit 100 degrees Fahrenheit (38 degrees Celsius). Even a region called the Last Ice Area showed unexpected melting this year.

In the next couple of decades, the Arctic is likely to see summers with no sea ice.
