Greenland Ice Cores Reveal Long-Sought Temperature Data

A new study suggests Greenland started warming about 19,000 years ago, along with the rest of the Northern Hemisphere, despite studies that had suggested Greenland warmed much later. The researchers also suggest that temperatures changed more in central Greenland than in the northwest and that such abrupt climate change is heavily dependent upon the seasons — largely a winter phenomenon.
