There’s a deceptive new kind of polar ice floating in the Arctic right now. It looks thick and stable from space, but in reality it’s fragile and can break apart upon contact. This is scary for researchers like David Barber. Satellite images had suggested that much of the Arctic was covered in multi-year ice measuring several meters thick, but the reality is that the cameras were merely picking up a relatively new form of “rotten ice” — Arctic ice in an advanced state of decay. This means the situation is worse than we thought. To learn more about David’s work studying the ice caps, visit go.ted.com/rottenice
