That this is news reflects only the reluctance of much of world leadership to acknowledge it. Anybody paying attention has known for over a decade that a +1.5C limit is out of reach. The question the world faces now is whether the 3C rise we're actually going to get is enough to trigger non-human forcing through various feedback loops dumping carbon into the atmosphere in the form of CO2 and CH4, to require runaway warming as the future. I'm not optimistic.
