There is literally nothing we can do to stop what's going to happen over the next hundred years. Elimination of emissions and massive investment in CO2 capture over the next hundred years might make the next hundred less terrible?
So my philosophy is to try and enjoy what we have as much as I possibly can and vote and support what little change I can.
Sadly, as climate declines, I suspect there will be a negative feedback loop. Economies will decline and the capability & willpower to invest in the future will decline along with the funds needed to improve the world.
