> It's quite amazing watching the "climate change isn't real" folks transition to "climate change is no big deal", then to "climate change is too hard/expensive to deal with".

At the top level (of government and corporate entities) those people always knew it was real, the messaging just changed as it became harder to keep a straight face while parroting the previous message in the face of overwhelming empirical evidence.

Exxon's (internal) research in the 1970s has been very accurate to the observed reality since then.

They just didn't care that it was real because they valued profits/power/etc in the moment over some difficult to quantify (but certainly not good) future calamity.

You would think they would care at least in the cases where they had children and grandchildren who will someday have to really reckon with the outcome, but you'd be wrong, they (still) don't give a shit.
