This reminds me of the "Anarchist" (scare quotes) publication "Desert". It has the same outlook and prescription. Give up.
The socio-political facts are: hyperfragile modern civilization will collapse following agricultural failure. We’re not going to geoengineer our way out of this. There will not be a revolution. Fascism is ascendant and governments will protect billionaires and sacrifice the working class.
This is the issue with doomerism. It's comfortable. It's certain. And it doesn't ask anything of you but to prepare and wait for the end.
This kind of rhetoric is very similar to certain kinds of counterrevolutionary state agitation within revolutionary groups. It has the same result: checked-out people incapable of fighting for their liberation. I definitely don't blame anyone personally for developing this kind of world outlook but collectively we should be very suspicious and critical of these kind of ideas.
The author's argument against "net zero" and other climate change mitigation is highly reliant on a few people's testimony that certain conventional ideas of how this may be achieved are impossible. Then they go on to claim the entire endeavor is impossible. This is a very premature conclusion to draw. The world is, unfortunately, still in a very naive and early stage of dealing with this extinction-level catastrophe. As this gets worse, even the ruling class will be forced to confront that market-based approaches will not work and something much more comprehensive and coordinated will have to be tried. Giving up based on the shortcomings of the narrow solutions presented in this article would be very counterproductive. There's a book along these ideas called "Climate Leviathan" that you may want to check out if you're interested.
It can't be denied that things are looking very bad. But the future is not yet determined. There are positive developments on some fronts: increasing world "multi-polarity", the slipping grip of the world hegemon on the third world, a revival of the labor movement in the first world, etc. On the whole, things are probably going to get worse. But this same likelihood also means more opportunities for revolutionaries. As capitalism becomes more and more incapable of dealing with climate change, the destruction of the imperialist world order, all the other problems which plague the world today; the easier it will be to defeat.
Idk who will read this and I know I'm in /c/doomer but... please don't give up.
