My hottest take is that this is basically inevitable. Wealthy countries just weren't willing to make the kind of sacrifices necessary to reduce CO2, and it's too late to stop the worst outcomes. Soon our choices will be living in a hellish desert or artificially cooling the earth any way we can.

Throwing shade
Finally got around to reading what this bright startup’s plans are.
First point: they won’t tell anyone what they actually plan to fill up the stratosphere with to reduce sunlight at the surface.
Great beginning.
They say it’s not sulfates. (Which would cause acid rain. Which would be Bad.)
Other alternatives are calcium carbonate, titanium compounds, zirconium compounds (as expensive as it sounds), and probably other things I don’t know about. Unlike sulfates, these all clump soon after ejection which reduces effectiveness unless you use expensive workarounds.
So, anyway, right off the bat, typical bullshit to hoover up taxpayer money from governments desperate to do something, anything.
