> when the effects of climate change are undeniable

I understand your meaning, but kind of a tragically funny statement given that really that's just... now.

So, it'll just be a continuation of the same insane talking points as today - "Weather has always changed" or "There have always been hurricanes/droughts/floods" while ignoring or denying or not understanding increasing frequency or intensity.

Also a lot of nonsense that because someone somewhere was still polluting (china, billionaires, whoever) that there was no benefit in decreasing pollution where we could, as if the problem was a binary where the only options were "zero pollution" and "unlimited pollution".

That would be admitting you got it wrong. It'll actually be "It was all due to sabotage (wrecking) by Antifa. ICE stormtroopers are on the way to round them up now. Incidentally Antifa is anyone who didn't vote for Trump".

The one problem will be that, at least at the lower levels, the US still has a mostly functioning judiciary so they'll have to either set up some parallel system to sentence people, e.g. the Military Collegium of the Supreme Court of the USA, or set up a special judiciary to do it, e.g. the People's Court (Volksgerichtshof).
