Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted

Environmentalists once saw abstraction as the biggest obstacle to climate action. How, they wondered, could one focus the public on the distant future? Today, we confront the opposite problem, with the very immediacy of the crisis generating a strange paralysis. When the Intergovernmental Panel on Climate Change warned that global heating made extreme flooding more common, its new report at the end of February spurred relatively little discussion – in part because of the water covering swathes of Queensland and New South Wales. As tinnies plucked desperate residents from the deluge, who could give due weight to the warning from Prof Brendan Mackey, one of the IPPC authors, that the science clearly projected “an increase of heavy rainfall events?”

This new research, written over four years and published in Reviews of Geophysics, finds that the true climate sensitivity is unlikely to be in the lowest part of the 1.5-4.5°C range. The analysis indicates that if atmospheric carbon dioxide levels double from their pre-industrial levels and are maintained, the world would probably experience eventual warming from 2.3 – 4.5°C. The researchers found there would be less than 5% chance of staying below 2°C and a 6-18% chance of exceeding 4.5°C.

New study shows low levels of future global warming are far less likely than previously thought. Very high warming is also slightly less likely.
