I struggle with the climate change question because our governments clearly don't see it as a problem, and certainly not even approaching an urgent one.
I think, when you see the wanton profligate decisions that the leaders make, it couldn't be a clearer signal from them that they personally categorically do not believe the message that they're giving out.
When Joe Biden (and he is very far from the only world leader like that) flew several of his own vehicles from the USA to the climate conference in Glasgow (and back) - where there are already any number of luxury vehicles that could have been hired - that really was the equivalent of the Archbishop of Canterbury deciding to do a one-man Chubby Brown & Jim Davidson tribute festival and then expecting anybody to take his next sermon, or indeed him, at all seriously again.
I’m not disputing but am sceptical. There are any number of scientists who query these climate-change models and none of them appear to be lunatics.
I know it's not exactly the same thing, but... whatever the established facts are, all scientists know that any research positions, grants and jobs will be closed to/lost by them if they express any dissent from, or even question, the official line; in the same way that a great many GC people grudgingly stay quiet or grit their teeth and toe the line in order to avoid cancellation and job losses - and therefore would appear by default to be in complete agreement with the prevailing messages about how many different genders there are, there's no such thing as fixed biological sex, some children need puberty blockers and even surgery for 'gender' reasons, it's just common decency to ask people what their pronouns are etc.
What I'm saying is that, even if you are convinced that you have all of the facts about anything indisputably correct, when there is a powerful culture where people are simply not allowed to question or disagree with those facts, it's impossible to genuinely claim that opinion is unanimous.
