I have mixed feelings about this analysis. Humans have exceeded planetary boundaries. We have to consume less. The ultra-rich are clearly exemplars of toxic, destructive over-consumption. If they invest in useful economic activity, fine; but superyachts and private jets are contemptible, childish indulgences. So yes, Oxfam are 100% right to point this out.

On the other hand the collective response to climate breakdown is one massive shrug – either look the other way altogether, or point the finger somewhere else: "It's billionaires! It's all China's fault ("Why don't you go there and protest?"), it's the fault of the military; it's the fault of white colonialists; it's the fault of greedy corporations; it's the fault of industrial agriculture; it's the fault of governments; it’s caused by overpopulation, etc etc.

The commonest cry I hear is "There's nothing I can do as an individual.....". If the millions of people who said that got off their backsides and prioritised their kids' future other their own lifestyle, there'd be a lot we could do.

Ducking responsibility is the tragedy of the commons writ large.

It's all irrelevant. The only thing that matters is action. Either we get active - me , you all of us – or we watch the global economy go down in the next few decades amid mass migration and regional conflict.

What are the chances of success? We almost certainly have +2oC now locked in, probably by around 2060. But if we sit around with a paper bag over our heads, we’ll hit +4oC or more. There’s nobody else going to fix this – it’s up to us. You. Me. Now.
