The Thwaites Glacier in Antarctica is "holding on by its fingernails." That's according to one of the co-authors of a new study about how quickly it’s melting. It’s about the size of Florida and has been dubbed “the doomsday glacier” because it could raise global sea levels by two feet.
Boulder scientist Ted Scambos has watched the impact of climate change on the glacier for three decades. He spoke with Ryan Warner in March.
