Warmer Current Is Carving Away Greenland Ice Sheet From Below, Scientists Find

The Greenland ice sheet is melting faster than ever recorded in modern history. New research finds that the world's second-largest ice deposit is not just melting from the surface but from below as well, which adds a new twist to consider when predicting global sea level rise. The Arctic ice sheet stores large quantities of frozen water extending 1.7 million square kilometers (656,000 square miles) long, according to the National Snow and Ice Data Center. In recent years it has seen unprecedented melting — seven times faster today than in the 1990s — that is likely to be intensified by the climate crisis. Scientists estimate that if the Greenland Ice Sheet completely melted, sea levels would rise by about 20 feet.  Read more....
