Greenland Ice Sheet Nearing Point of No Return for Sea Level Rise

Carbon emissions are halfway to a tipping point that would trigger 6 feet of sea level rise from melting of the Greenland Ice Sheet, according to new research. Once we have emitted more than 1,000 gigatons of carbon in total, we won't be able to stop the southern part of the Greenland Ice Sheet from melting entirely in the long term, even if we would entirely stop emitting carbon then. The further the Earth overshoots the first tipping point of 1,000 gigatons of carbon emissions, the faster the Greenland Ice Sheet will melt.
