These models always assume that direct carbon capture technologies will extract ridiculous amounts of the CO2 out of the atmosphere.
Also 3C will be devastating as is though. That’s not including biodiversity loss, ocean acidification, and rising sea levels.
I personally think it will take a complete shift in human mentality. One that will only come about via artistic movements, whether that be music, painting, film, or even propaganda posters.
IMO, art is the most important factor for bring about such a massive cultural shift. Kind of like how art in the Renaissance caused people to view life more scientifically and logically instead of based purely of faith.
Similarly, art from the the hippie movement in the 70s promoted peace and love instead of competitiveness, war and destruction.
