I'm totally novice in scientific understanding/topics/etc.. 

 It terms of how we see evolution as a long and gradual process, it would seem that the time (howeverlong) leading up to extreme global temperatures would kill us before we would have a chance to adapt. However, there have been instances where a specific evolving or adapting happened rather quickly, but those events usually still took quite a long time to "happen". Then again, how quickly we could evolve/are evolving appears to be a difficult thing to predict, so maybe my initial question is flawed. I simply am asking it in a loose manner, hoping for some illumination even if my question turns out to be totally bogus. Lol.
