Endangered North Atlantic right whales are disappearing from their native waters, a serious danger for a species with only 340 animals left. The mystery behind this change took NPR's climate reporter Lauren Sommer 2,000 miles away to the world's second-largest ice sheet, sitting on top of Greenland.
On today's episode, Lauren takes Short Wave co-host Emily Kwong on an expedition to Greenland's ice sheet and then to the Gulf of Maine to break down the ripple effects of climate change.
