Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper published in Nature Communications. "The Greenland coastline is going to experience quite a different outcome," says lead author Lauren Lewright, a Ph.D. student in geophysics working at the Lamont-Doherty Earth Observatory, which is part of the Columbia Climate School. "Sea level in Greenland is actually projected to fall."
