I bailed out half way, but despite the disclaimer, that post does sound like climate change denial.

"Dealing with it would be just as bad as not dealing with it" appears to be the core of your claim, and I don't think thats backed up by anything I'm aware of. It is a fairly common trope of people who would be widely described as climate change deniers though.

Even more so, dealing with it say 20 years ago would have been even more straightforward.

We couldnt do it because we couldbt co-ordinate, like the prisoners dilemma, not because the two outcomes were equally bad but by working towards out own best outcome we've headed towards the worst overall outcome.
