Northeast Greenland Begins Ominous Collapse — Giant Zachariae Isstrom Most Recent to Destabilize

robertscribbler : "In total, more than 4.5 billion tons of ice is now estimated to be flooding out from this glacier and into the ocean each year. That’s a mountain of ice about 4.5 cubic kilometers in size hitting the world’s waters from just this single glacier every time the Earth completes one circuit around the sun. In other words, Greenland just opened a new floodgate to the North Atlantic. Researchers publishing the study estimate that it will take between 20 and 30 years for the glacier to melt back to an underwater ridge line that should somewhat slow its melt. But the real news here is that a human-forced warming of the globe has set a monstrous pile of ice, once thought stable, into a motion that will result in yet more global sea level rise."
