Hadley Centre - no GHG emissions reductions = 5.5 to 7 deg C warming by 2100
Green Home Huddler —
... [image] The Hadley Centre has come out with a projection of global warming by the year 2100 under 4 different scenarios. Under the no emissions cuts scenario, the planet warms 5.5-7 deg C by 2100. "This would lead to significant risks of severe and irreversible impacts." What surprised me is their conclusion that if we managed a 47% decrease in emissions by 2050 (as compared to 1990 levels), the planet would only warm 2-3 deg C. [image] I would have expected a larger degree of warming under a 50% emissions cuts scenario. ...

Grist - the Latest from Grist —
... The consequences of 5.5°C warming by 2100, which Hadley says is "likely" on our current emissions path are all but unimaginable -- mass extinction, devastating ocean acidification, brutal summer-long heat waves, rapidly rising sea levels, widespread desertification. But they are rarely studied or articulated by scientists who can't imagine humanity would be so stupid as to let this happen. I have tried to piece them together them together from the scientific literature (see " ...
