WebMar 16, 2024 · All total, Greenland and Antarctica have lost 6.4 trillion tons of ice since the 1990s. The resulting meltwater boosted global sea levels by 0.7 inches (17.8 millimeters). Together, the melting polar ice sheets are responsible for a third of all sea level rise. 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.
