And indeed, it already has. The thermal range of human habitation varies from the hottest jungles and deserts to and past the Arctic circle, far greater than any possible proposed thermal change model. And that range was established in far prehistory, without all the technological tools and knowledge we currently have available.
“The thermal range of human habitation”
It is more than simply the thermal range.
Humans have both “caused” and adapted to changes in the loss and the predominance of various flora and fauna - throughout human history, and still LIFE rit large and humanity and a “habitable” planet have all survived.
Can it be any less now when our technological abilities are so much greater? No, it can’t.
