Rule 1 of life: be skeptical when someone presents their opinion as facts.

Looking at Western European countries like Germany, the Netherlands and the UK to an extent, the road to net-zero is disrupting. Probably because necessary steps have been delayed until the last moment. Large numbers of refugees have a destabilising effect on democracy as well.

Some steps that are necessary for net-zero are expensive investments (like heat pumps) that are causing conflicts in society. Going ahead with it as well as delaying is sure to be met with very loud resistance. Don't think that Germany can miss it's climate goals without some serious protests, perhaps worse than they've ever seen.

At the same time, I wonder how well UK households are going to deal with even higher food prices as the percentage of failed harvests increases. There isn't a lot of buffer space here.

It's not so much whether rich countries have enough money to deal with climate change, but rather how well democracy will fare when it's under duress.
