Arctic ‘Ice Refuge’ Envisioned As Region Warms Rapidly in 21st Century


As the Arctic rapidly warms in the 21st century and Arctic sea ice largely disappears in summer, a strip of year-round ice is likely to remain to the north of Greenland and the Canadian Arctic archipelago, providing a refuge for some sea-ice dependent wildlife, such as polar bears and ringed seals, according to researchers. A panel of scientists at the American Geophysical Union meeting in San Francisco said the remaining band of ice could provide a haven for some iconic Arctic creatures, although the disappearance of the vast majority of summer sea ice, probably by mid-century, will undoubtedly be bad news for polar bears, which use the ice as a feeding platform to hunt ringed seals. The remnant strip of summer sea ice will likely exist because prevailing winds blow sea ice away from the shores of Russia and toward Canada, according to Stephanie Pfirman of Barnard College. She and colleagues from Columbia University, McGill University, and the U.S. government said it is important to protect this ice refuge from the oil drilling and mineral exploration that is likely to spread through other parts of the Arctic as summer sea ice disappears and the Arctic Ocean becomes navigable for part of the year.
