But the catastrophising of climate change is also harmful, and results in people proposing 'solutions' that seem likely to bring about an even faster collapse of civilisation.

One 2019 UK report (https://www.icax.co.uk/pdf/Absolute_Zero_Report.pdf) proposes a timeline that's been circulating on Twitter, involving the closure of all airports and shutting down all international shipping by 2050, while pricing 40% of traffic off the roads and banning beef+lamb. That (along with many more less-drastic but still significant restrictions) is what it would take to reach 'net zero' with current technology.

And that was written in 2019, when people were generally a lot more reasonable than they are in the post-Covid world.

(Do they even realise what they're proposing by 'no international shipping'... Amongst many other things, that means zero microchips for the UK, let alone complete technology products such as phones, TVs, or EVs)

Meanwhile in the real world (here in the UK), we've got a massive cost-of-living crisis, a collapsing healthcare system, a disaster of a property market, and a rising population that we're failing to build infrastructure to cope with. We have a a terribly incompetent government, and an opposition that seems no better. And we're living with the threat of WW3, the tail end of the pandemic, and now a banking crisis too.
