Yes I believe GP was focused on the catastrophe part. It's very likely correct that our CO2 emissions are warming the atmosphere ocean etc, but it's not clear that runaway warming is inevitable or that life or geology have feedback mechanisms that turn an exponential into an S curve. That is, after all, basically what natural selection tends to do. Turning the table again, even if there are corrective factors humans might have immense suffering before it stabilizes. So we don't know.

You didn't ask, but my opinion on it is that we'll probably stabilize on a cleaner energy source and find natural countermeasures when suffering ticks up. Any top down pressure to change things whole cloth seems doomed, no matter how benevolent. We're closed loop creatures.
