> It's much like climate science today: any dissent at all, even just questioning the predictions of catastrophe, immediately brands you as a heretic.

I'm not sure I understand this. We've added hundreds of gigatons of carbon to the atmosphere. There's no mystery here, it's basic physics and chemistry that this will change things, and it's accepted that we don't know exactly _how_ things will change. The alternative: "adding gigatons of carbon to the atmosphere will _not_ change anything" is simply non-sensical. It goes against the basic rules of physics and causality. I'm happy to be proved wrong here, I just legitimately can't see how an alternative position makes any sense.

Edit: I see you specifically pointed out "predictions of catastrophe", which if that is true (and not just the position of radicals on Twitter) is indeed unfortunate.
