Antarctic Sea Ice Reaches New Record Maximum

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 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

talk to the hand... =;

Bye for now, got to get back to work.

At least you finally agree that land ice is declining.
