When an ice cube melts, it creates a puddle. When an ice sheet melts, it raises sea levels. It sounds simple, but scientists have debated for decades whether both the Antarctic and Greenland ice sheets actually were shrinking — and how much that melting contributed to rising sea levels.
Now, a new study has provided the best evidence yet of how the polar ice sheets are responding to our warming world. In the study, published in November, an international team of scientists looked at 20 yea...
