The Greenland Ice Sheet is close to a melting point of no return: Once we emit about 1000 gigatons of carbon, much of the massive ice sheet will melt irreversibly: We've emitted 500 gigatons so far

Summary by Science Daily
A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.
