Meltdown Alert: Greenland Ice Sheet Nearing the Point of No Return

WebThe Greenland Ice Sheet is a frozen reservoir for 8 percent of all freshwater on the planet. Glaciers, such as the Petermann Glacier along the island’s northern margin, drain the interior, returning this water to the sea as icebergs. Melt water can accelerate the flow of a glacier by lubricating the underside as it scrapes over the rocky terrain. http://esciencenews.com/articles/2009/02/16/greenland.and.antarctic.ice.sheet.melting.rate.unknown tailwindcss whitelist class
