Curbing Climate Change: Why It's so Hard to Act in Time

By Timothy H. Dixon, University of South Florida This summer I worked on the Greenland ice sheet, part of a scientific experiment to study surface melting and its contribution to Greenland’s accelerating ice losses. By virtue of its size, elevation and currently frozen state, Greenland has the potential to cause large and rapid increases to sea level as it melts. When I returned, a nonscientist friend asked me what the research showed about future sea level rise.
