Hundreds of thousands of people have certainly died from climate catastrophes in the last two decades; heat stroke alone is reaching those numbers.
>>12100142Carbon is not the only greenhouse gas, and when people say that they don’t literally mean we’ll turn into Venus, they mean that we could pass an equilibrium tipping point beyond which the earth will be in an irreversible “hot house” state.
Very few holocene-adapted species will be able to survive a rapid transition to an oligocene-style earth (we could end up even hotter than that) so it’s pretty much game over unless we immediately start sequestering huge amounts of carbon and stop fucking burning hydrocarbons.
