LEAD: NASA scientists flew 33 eight-hour flights this spring (2015) to measure how Greenland and the Arctic are responding to climate change. 1. Greenland is huge: essentially an ice cube 1,500 miles long, 400 miles wide, and a mile and a half thick. 2. Instruments aboard the research plane measured where Greenland ice is growing in winter and where it is melting during the summer. TAG: Data indicates that overall, Greenland is losing ice, and its melt water is adding to the long-term sea level rise around the world.
