I'm inclined to agree.
For real-world examples: what stopped the Black Plague? Nothing, really. At least nothing humans did. It killed lots of people, scarred others, and eventually petered out. Humanity didn't solve that, we just survived it. We are pretty good at surviving, which is not at all the same thing as solving problems.
For that matter, we aren't that far removed from some of the worst bouts of violent excess in human history. There is no guarantee our "solution" to climate change won't be to simply kill off a large portion of the population, either systematically or by happenstance.
