Climate disaster could be curtailed within a couple of decades if net zero emissions are reached, new study shows
The world may be barreling towards climate disaster but rapidly eliminating planet-heating emissions means global temperatures could stabilize within just a couple of decades, scientists say.
For many years it was assumed that further global heating would be locked in for generations even if emissions were rapidly cut. Climate models run by scientists on future temperatures were based on a certain carbon dioxide concentration in the atmosphere. If this remained at the current high level there would be runaway climate disaster, with temperatures continuing to rise even if emissions were reduced because of a lag time before greenhouse gases accumulate in the atmosphere.
