Arctic ice at low point compared to recent geologic history

Less ice covers the Arctic today than at any time in recent geologic history. That’s the conclusion of an international group of researchers, who have compiled the first comprehensive history of Arctic ice.

“The ice loss that we see today — the ice loss that started in the early 20th Century and sped up during the last 30 years — appears to be unmatched over at least the last few thousand years,” said Leonid Polyak, a research scientist at Byrd Polar Research Center at Ohio State University.

Polyak is lead author of the paper and a preceding report that he and his coauthors prepared for the U.S. Climate Change Science Program.
