Remaining carbon budget to limit global warming to safe levels could be tiny

Researchers from the International Institute for Applied Systems Analysis (IIASA) in Austria and colleagues from the Grantham Institute at Imperial College London, the University of Leeds, MeteoFrance, and the Potsdam Institute for Climate Impact Research, have put forward a new way to understand and track changes in the “remaining carbon budget”. This is the total amount of COwe can still emit while having a chance to limit global warming to a certain level. Given that we are aiming to keep warming well below 2°C and preferably even below 1.5°C, this is an extremely important number to inform decision makers about how rapidly we have to bring our emissions down to zero, say the researchers reporting their work in Nature.
