Closer to 66 million.
It would be like not starting Cyanobacteria destruction of earth until after all of the Oxygen sinks were Depleted. The start of the Human Extinction event would be geologically when the first “man” existed. Also if you want to look at mass extinction I’d be will to bet it would take at least millennia to have humans be fully extinct even with a difficult climate.
The other issue is that I don’t think any of the mainstream climate models point towards human extinction as a consequence of global warming.
We are going to force a lot of species into extinction and the carrying capacity of the earth may drop but it’s unlikely global warming causes humans to be unable to technologically adapt.
Nuclear War, Pandemics, bio weapons, perhaps even AI is what you should be looking at when considering extinction.
