I think in that article Gates does quite a disservice to the climate change dialogue because he does not even entertain the possibility that the most severe of the effects of climate change is going to be massive population migration due to extreme weather and agricultural failures. His comment that climate change is not going to lead to civilization collapse fails to elaborate for whom.

Maybe he’s hoping for sea level rise these days. Enough to submerge a particular island.

Bill Gates changed quickly when he realized the damage to the environment that AI will cause I guess.

I think there's an "and" in that that article, not an exclusive "or".

Not how I understood it. It was about climate “vs” health not whether the climate is breaking down.
