Previous stories pertaining to Dr. Polyak's research: ARCTIC ICE
AT LOW POINT COMPARED TO RECENT GEOLOGIC HISTORY COLUMBUS, Ohio
-- 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. For decades, scientists have strived to
collect sediment cores from the difficult-to-access Arctic Ocean
floor, to discover what the Arctic was like in the past. Their
most recent goal: to bring a long-term perspective to the ice
loss we see today. Now, in an upcoming issue of Quarternary
Science Reviews, a team led by Ohio State University has re-
examined the data from past and ongoing studies -- nearly 300 in
all -- and combined them to form a big-picture view of the
pole’s climate history stretching back millions of years. “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 ov
