Phys.org: Rapid emissions reductions would keep CO2 removal and costs in check

„Emissions reduction efforts in the next decade pledged by governments under the Paris climate agreement are by far not sufficient to attain the explicit aim of the agreement—they will not keep warming below the two degrees limit,“ says Jessica Strefler from the Potsdam Institute for Climate Impact Research (PIK), lead author of the analysis published in Environmental Research Letters. „To stabilize the climate before warming crosses the Paris threshold, we either have to undertake the huge effort of halving emissions until 2030 and achieving emission neutrality by 2050—or the emissions reductions would have to be complemented by CO₂ removal technologies. In our study, we for the first time try to identify the minimum CO₂ removal requirements—and how these requirements can be reduced with increased short-term climate action.“
