The idea that the humans will somehow adapt to this is the stupidest idea I've ever heard. Koch bros are pushing the same idea, on the evolutionary level, that humans will learn to live.
To me humanity is already dead, we are eternally doomed. We just don't know it yet. It's better to realize and accept it[2], as if we're told we have cancer and our days are numbered. This is a very pessimistic approach, but it is an honest one and may help mitigate problems for future generations.
