If I may add to your sentence, specifically the last claim in your quote is what puts their train of thought on a collision course with reality.

Life adapts, when it can. The rate of change you mentioned ensures that a majority of life will not be able to adapt and it's not impossible that another K-T level extinction event is already taking place.

Geologically speaking, the speed at which the Earth is changing from human-induced climate change could just as well be a meteorite impact. Looking at global conflict resolution ability I fear that we have no hope to stop it.

It's also "not impossible" that a meteorite wipes us all out tomorrow. Which serious scientist is predicting a K-T level extinction event?

Serious predictions are talking about a couple of degrees over thousands of years. That's not out of the ordinary in terms of variance for life on earth right now. Sure, some species may have to migrate, some will go extinct one way or another, but not a K-T level event.

Serious predictions are talking about a couple of degrees over the next century. That's very different. It may be hard to separate the climate change extinctions from the regular habitat destructions that are already ongoing, though.
