On Sept. 19, 2014, the five-day average of Antarctic sea ice extent exceeded 20 million square kilometers for the first time since 1979, according to the National Snow and Ice Data Center. The red line shows the average maximum extent from 1979-2014.

Why is almost all the snow gone on Mt. St. Helens? When I was a kid it was covered in snow.
Oh, it's a VOLCANO? Volcanos are really hot? The land on a volcano can heat up? I didn't know that. Thanks.

"Antarctica is a land of ice. But dive below the West Antarctic Ice Sheet, and you'll find fire as well, in the form of subglacial volcanoes. Now, a new study finds that these subglacial volcanoes and other geothermal "hotspots" are contributing to the melting of Thwaites Glacier, a major river of ice that flows into Antarctica's Pine Island Bay. Areas of the glacier that sit near geologic features thought to be volcanic are melting faster than regions farther away from hotspots. This melting could significantly affect ice loss in the West Antarctic, an area that is losing ice quickly, said Dustin Schroeder, the study's lead author and a geophysicist at the University of Texas at Austin."

The summit of Mount Erebus casts a long shadow out over the Ross Sea. Mount Erebus is the most active volcano in Antarctica—and one of a few in the world with a permanent lake of molten lava in its crater. Photograph by George Steinmetz, Corbis
"The heat from the volcano could increase melting at the base of the glacier and meltwater could act like a lubricant that makes the overlying ice flow out to sea faster. Global sea levels could rise by a small amount as a result." National Geographic

At least you finally agree that land ice is declining.
