AFAIK the extreme, apocalyptic statements you are making are not supported by the science such as the IPCC.
Other people here are asserting that an abrupt and urgent transition away from fossil fuels 'will crash the economy and kill off most of the population' (which I take to mean >50%) without offering any citations for that claim whatsoever.
considering modern society relies on Diesel trucks and fuel oil-burning ships to feed itself, those numbers don’t seem too crazy. If we stopped using fossil fuels tomorrow we’d have mass starvation everywhere within weeks.
So I guess it depends on what you mean by abrupt. I think we could certainly do something like add a $2/gallon tax on gas and diesel fuel without that happening, and it would reduce driving and emissions, but I would see the politicians who passed that law getting voted out at the next election as the people refuse to have their current standard of living lowered.
