Fine if you want to call it glib but I think the point stands: the UK has power and influence on the world stage despite the 'small island' stories conservatives like to tell themselves (and everybody else), and there is a relationship between the affluent west and the growing economies of the east. It's not master/servant in quite the way it used to be and China is now well on its independent path and will be responsible for whatever messes it makes along the way, but the fact remains that there's hardly any industry left in the 'developed' nations and yet all the goods - the products of industry still - keep rolling in. Hence these countries share the responsibility of China's emissions, and if they really wanted to do something about it they could.
I got that you didn't want to endorse GB News, and I agree that it's a compelling argument on the face of it (though I think its real power is that it offers a rationalisation for ppl to avoid taking the issue seriously) - which is why I tried to address it. Maybe it won't persuade anyone, maybe it will be received as condescending and disdainful. Probably some people can't be persuaded anyway, for whatever reason. Doesn't make it untrue. Maybe you could try it out on your pub friends next time they say the solution is to nuke China?
cheers, I
PS: I sometimes watch GB News too. A lot of it is dishonest, but I think they're right to flag up the possibility of climate authoritarianism, which the left is mostly blind to, as it was over covid. Unfortunately the right-libertarian philosophy means they're fundamentally more concerned about the freedoms of business than they are of people, which IMO means the way they blow the whistle will only ever align with corporate interests and ultimately act to undermine any movements genuinely acting in the interests of the working class. How are they on unions? How were they on Corbyn?
