We could cease burning all fossil fuels tomorrow and we'd still have to resort to geoengineering. Read the IPCC projections. All of the ones that keep us below 3c require 'negative emissions'. That's code for DAC, a technology that we've only ever deployed to small pilot projects, deployed more widely, more quickly, than we've deployed any technology ever.

TLDR: We're gonna have to use sulfate injection until we can transition our economy
