Climate-Studying Seals Bring Back Happy News

The elephant seals that sent data back from underneath Antarctic ice hadn't exactly volunteered for the task—the sensors were glued to their heads. But it was for a good cause. By taking advantage of animals much better equipped to study frigid polar waters than we humans are, climate scientists collected valuable observations. They even got a rare piece of good news: Some ice shelves aren't melting as fast as we thought.
