By my understanding, even if we stopped all of our carbon output immediately, there’d still be a devastating 2C increase in the average temperature of the earth.
According to an analysis featured in the recent IPCC special report on 1.5C, reducing all human emissions of greenhouse gases and aerosols to zero immediately would result in a modest short-term bump in global temperatures of around 0.15C as Earth-cooling aerosols disappear, followed by a decline. Around 20 years after emissions went to zero, global temperatures would fall back down below today’s levels and then cool by around 0.25C by 2100.
I.e., if we’re at +1.2C today, the maximum would be +1.35C.
I don’t think this is true:
