Charles Moore is a well-known denialist. Earlier pieces of his have been exposed for the pack of lies they are: in one case the Daily Telegraph (a right wing paper which to its shame will print such garbage) had to offer an apology. It's odd: EXACTLY the same conspiratorial mentality is at work in climate change deniers, creationists and Bible literalists generally. They wear an ideological blindfold and resist all attempts to have it removed so they can see the light. I am not sure how you deal with such people, clearly not by using rational argument. But the trouble is, they're not actually stupid and have often insinuated themselves into positions of influence.
Brexit, among other things, is a distraction from the far more pressing need to address the climate crisis. Thunberg is right, Moore is wrong, it's that simple.
