It is kind of astonishing to me to witness the discussion in these comments proceeding civilly and with actual regard to the science. In my experience this is vanishingly rare. It's extremely refreshing. At risk of ruining that civility, I'd like to address some aspects of climate scepticism various other comments are touching on.

It is not difficult to see that a reasonable person may ask that if the UN is correct in saying 30% of climate change is due to methane[1] and this paper is correct in saying methane is 30% less effective at warming than we thought, then isn't this whole climate change problem potentially ~9% smaller than we thought? And isn't that actually pretty big? Big enough to potentially have policy implications?

I'm quite sure it's not that simple but nevertheless as a starting point for discovery it's a decent question. It's also a question that will be met with astonishing levels of derision on social media, mainstream media, and in society more generally. Merely asking it will have large international media outlets like the BBC openly describing the questioner as a 'climate sceptic/denier' which, while some may wear it as a badge of honour, actually serves the purpose of shaming them publicly for wrongthink. Social media will of course be far worse in this regard.

We now live in a world where it is popularly considered valid to provide a political (to put it kindly) response to a scientific question. It is, of course, both invalid and indefensible.

I have no ideological aversion to the idea that climate change is real and a serious threat, but the quality of societal discourse on the topic has become so poor and so overtly political that there is absolutely no basis upon which I can accept either of those assertions as _actually scientifically_ true (short of becoming a climate scientist and spending the next however many years personally reviewing all the literature). For me to accept these assertions as fact would be indistinguishable from a declaration of religious faith. It isn't going to happen.

Moreover the conduct of the pro-climate change 'lobby' from the IPCC to the BBC to Just Stop Oil activists has, on the whole, fallen so far short of the standard demanded by the severity of the problem they espouse that I simply don't believe them very much anymore. In my view--and I claim no authority on this matter, this is just how I see it--climate change may well be real and an existential threat, but it may also be a bureaucratic fantasy mistakenly grown from kernels of misunderstood or mistaken truths that has gotten so completely out of control that it's now controlling us. It could also be somewhere in between, or something else entirely: I don't know and I cannot know so long as society keeps excluding valid voices with valid questions.

I suppose I'm a climate sceptic then...but when it comes to deciding between being a sceptic or taking a leap of devotional faith, what choice do I have? Luckily it seems to me the way forward is the same in any case: the pro-climate change people, being the ones comprehensively 'winning' the 'argument' at the moment, need to show a little humility and engage in open debate with the well-meaning sceptics without the ad-hominem attacks, the gaslighting, the censorship, etc. It really is that simple, and the fact it’s so forcefully resisted should, in my view, give us all pause for thought.
