One other thing to consider is that it looks increasingly likely that we are close to the end of the climate change denial game. Just like with big tobacco there is a limited period where the 'evidence is inconclusive, it's a myth, our own studies show etc.' excuses work. With tobacco it was when people saw their own families dying of cancer that they abandoned that line . With climate we are actually seeing the changes now (Australia in permanent drought, artic melting, weird summers etc) and public tolerance of denial seems to be shifting with things like Extinction Rebellion and this topic.

To borrow a phrase that Warnock could have written himself: what do you do when you aren't good enough to play the ball? You try to play the player instead.
