Matt Walsh is an unserious goon at best, an actual moron at worst.

But the reason that this sort of anti-science propaganda might actually work on well- intended people is because we don't advertise our major successes anymore. Or rather, we never really did advertise them enough, but as those successes became less visible compared to, say, a polio vaccine, just as it took scientists to inform us of the problem, they need to inform us of wins too.

When I was a kid in the 90s, we had a lot of alarm bells going off about the Ozone Layer, about acid rains, and climate change (termed "global warming" then). None of these were particularly visible problems to most people. Each of these became massively politicized, but the fix for the first 2 was a relatively narrow remedy: find and implement replacements for hydroflourocarbons through environmental regulations, and cut mainly two compounds, sulfer dioxide and nitrogen oxides, from fossil fuel power plant emissions through cap and trade regulation policies and smokestack scrubbers. And it worked quite well, to the point that the ozone layer is repairing, as are ecosystems previously ravaged by acid rains.

But scientists and the media never advertised that success nearly enough. Honestly we should have been politicizing that success, even, as much as we did the problems. Now it just seems to most like the problem quietly got forgotten like it never really mattered, rather than that it was a massive problem and we fucking fixed it through science, regulation and international cooperation. And that apparent disappearance of the problem without any noticeable change for the average Joe, and the resulting skepticism that it was ever a problem at all, has infected the one ongoing problem, the biggest and most complex of the problems, climate change.
