Unfortunately it’s not a single tiktok video from one random guy.

There’s a fairly large amount of disinformation out there, in a few cases spread by scientists who don’t specialize in climate. I know a climate change denier who spent some time reading on the topic, including a scientist’s blog (not a climatologist) who regularly instill doubt on the latest findings on climate change. He could genuinely say he read a lot on this topic, but it was in large part from crappy sources.
