In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study led by CIRES Fellow Mike Willis, an assistant professor of Geology at CU Boulder. That dwarfs the ice's previous average speed of about 2 inches per day and has challenged scientists' assumptions about the stability of the cold ice caps dotting Earth's high latitudes.

“In a warming climate, glacier acceleration is becoming more and more common, but the rate of ice loss at Vavilov is extreme and unexpected,” said Mike Willis, CIRES Fellow and lead author of the paper published this week in Earth and Planetary Science Letters.
Glaciers and ice caps like Vavilov cover nearly 300,000 square miles of Earth’s surface and hold about a foot of potential sea-level rise. Scientists have never seen such acceleration in this kind of ice cap before, and the authors of the new paper wrote that their finding raises the possibility that other, currently stable ice caps may be more vulnerable than expected.
