Step-by-step explanation:
People are superbly adapted to climate change. It even appears likely that climate change, in the Rift Valley of East Africa particularly, may have been a key evolutionary pressure in development of the modern human mind. The really big problem is that a huge number of other species upon which we rely, both animal and plant, are not as adaptable as we are.
To say that we aren’t adapted generally to climate change is not true given that we had coexisted at at least somewhere on this planet despite conditions proving far different, generally speaking, in many places relative today. Then what is the difference between then, now, and the future? We didn’t live to scale back then as we do today! We didn’t have the populations that require more energy resources, that also impact our planet in far different ways relative the past. This is important because, yes , our evolution may have attuned us well in surviving in small groups as it turns out, but what about scale survival of populations? That is a new leaf to be turned with respect to possibilities. The truth is we don’t know how climate change will impact our civilization even if smaller groups of humans manage to survive given enough change. We don’t know whether by mitigating certain climate cyclic trends (via anthropogenic forcing) whether we will have made ripe conditions for contagious diseases far more virulent relative to existing vectors. We don’t know whether we will have created conditions that result in industrial agricultural collapse. We don’t know how water security in the future will play out, and if the past proves true likewise to the future, extinction events could provide even greater challenges to scale survival of future populations. If we are always looking to the near past in equipping ourselves to survive in the long term future, this may exemplify our adaptive failure to climate change in so far as our scale advantages to survival especially if long range considerations are necessitated.
