Evidence of Climate Change in Alaskan Fish

Guest: Mark Belk, PhD, Professor of Biology, Brigham Young University If you’re looking for evidence of climate change, head to Alaska, says BYU biology professor Mark Belk. He’s spent the last five summers on Alaska’s Admiralty Island, where there are more grizzly bears than humans. He takes BYU student scientists up to troll the waters of the Gulf of Alaska and the fish they reel in are telling a story about the changing environment.
