The Paris Agreement goal of capping global warming at 1.5 degrees Celsius will slip beyond reach unless nations act now to slash carbon pollution, curb energy demand, and suck CO2 from the air, according to a draft UN report.
“There is a very high risk that under current emissions trajectories, and current national pledges, global warming will exceed 1.5C above pre-industrial levels.”
Hans Joachim Schellnhuber, Potsdam Institute for Climate Impact Research
“There is a tipping point on sea level rise” – driven mainly by melting icesheets on Greenland and Antarctica – “somewhere between 1.5C and 2C,” said Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research.
“We don’t have any margin for less than total commitment,” said Chris Field, Director of the Stanford Woods Institute for the Environment in California and a former co-chair of the IPCC’s Working Group II.
