Scientists believe that the polar regions are the first to feel the heat from global warming.
In the Arctic’s Northern Bering Sea there’s been a significant reduction in ice, and the effects are reverberating through the ecosystem. Scientists are seeing sea creatures – from clams to seals to gray whales – escape the warming waters by moving north.
Earth & Sky’s Lindsay Patterson spoke with Jackie Grebmeier, a professor of biochemistry and ecology at the University of Tennessee at Knoxville. She’s been studying the Northern Bering Sea for 20 years, and says that what’s now underway is a complete shift in Arctic zones.
