Where’s the water going? Where will the water go?

❝ There’s still much that remains unknown about the Greenland ice sheet, which at roughly 650,000 square miles is more than twice the size of Texas. The sheet, up to two miles thick, contains enough ice that, if it all melted, would raise oceans around the world by 24 feet. Precisely how the ice melts — half or more by warming on the surface, the rest by ice sheet movement toward the sea, where it melts or calves off as icebergs — can greatly affect how much and how fast the seas rise.

Greenland is currently losing an average of about 260 billion tons of ice per year; at this rate, it would contribute about two inches to sea level rise by the end of the century. This ice loss is estimated through gravity measurements by satellites, but computer models that simulate physical processes are used to estimate the surface runoff. The field study was meant to improve those models by providing on-the-ground data on the flow of meltwater.

Science, of course, isn’t invoked just to give hope – or spread fear. Facts are facts. It takes corrupt politicians to turn them into fake news. RTFA.
