This has resulted in a situation where the Left, who abandoned science decades ago, pretend to care about it, while the Right--which has long had an ambivalent relationship with reality--has decided to go full-post-modern and construe all facts as pure social constructs, which is exactly what the Left has been saying for a long time.
Almost none of the discussion of "climate science" in the public sphere has anything to do with science, and if you're an actual scientist with relevant expertise and you say anything about the science you will get beaten up by both sides.
As a computational physicist I've given my opinion on occasion that climate models are non-physical and therefore non-predictive, no matter how well-tuned they are to past climate (because only the correct physics can extrapolate the past forward, and the unphysical approximations in climate models are not small in the relevant sense.) What climate models do show fairly convincingly is that we are increasing the Earth's heat budget by 1.6 W/m2 or so, which is in the range of 0.5% overall, and this is plausibly a very bad thing.
So because I criticize climate models the Left attacks me as a denialist, and the Right embraces me as one, whereas I'm actually saying the models give a pretty decent reason to take some fairly mundane steps, like implementing carbon taxes and tariffs. The "tariff" part is important because it exports the cost of emissions to other jurisdictions. At this point the Right attacks me as being a socialist taxer (because taxes are socialist?) and the Left attacks me for not wanting to "change everything" (because that always works so well.)
There simply isn't any science in the "climate science" debate. It's all politics.
