Too late for what? We've already locked in WW2-level casualties by mid century from hunger and heat stroke due to climate change. The fight now is to keep the deaths merely to WW2 levels, and not those equivalent to a nuclear war. There is still much to gain by fighting for change, but we're not getting out of this unscathed. Realistically, by 2050, we're set to lose between 2% and 10% of the total human population to famine and heat.
