Flying over the Arctic Ocean, NASA researchers battle brutal crosswinds in aircraft loaded with cutting-edge instruments. Their mission: to unravel how sea ice and clouds interact. Some clouds trap heat, hastening the melt. Others reflect sunlight, slowing it down. To make sense of sea ice’s rapid decline, they skim dangerously low across the ice edge, decoding the data that will help predict the Arctic’s future.
