> I think it's pretty reasonable to think that an extreme climate would cause extreme mortality.

Classic equivocation fallacy on the word “extreme” in two different contexts.

If our arguments are so transparently wrong, it makes it easier to dismiss climate change.

> So, are you suggesting that we actually have plenty of time to deal with climate change

As Babbage put it, I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
