Honest question: is there any chance that this does NOT end in an attempt at climate engineering, i.e. shooting shit into the atmosphere to cool the planet?

I just can't imagine world nations are going to accept the catastrophic consequences that are incoming. Eventually, when things look bleak enough, it will become politically viable to propose such strategies. Obviously it is not at the current moment. But a cynical part of me just feels that it is just a matter of time. And that governments know it is just a matter of time, and they are preparing for it.

Asking people to change their habits or drastically alter their economies in a short period of time is, from what I have read, just a complete non-starter. I welcome arguments explaining how I am wrong.
