One of the creepier geology papers I've read was about how in the end-Permian mass extinction (which is characterized by extreme volcanic CO2 outgassing and warming) the actual kill mechanism might have been when pulses of sulfur aerosols masking the warming rained out and the temperature spiked
A lot of people are going to lose money on this. Solar radiation modification only makes sense if followed by large-scale carbon dioxide removal, and we ain't got that.
A 25-person startup is developing technology to block the sun and turn down the planet’s thermostat.

We find an AMOC collapse would exacerbate drought conditions across Europe, linked to reduced precipitation. In combination with climate change droughts are expected to become more frequent and severe.

With current pledges, the world's on track for 2.6°C of warming in 2100 compared to preindustrial levels.
10 years ago, before the Paris agreement, it was 3.6°C
20+ years ago, we thought it would be 4-5°C
So 2.6°C is better, but the problem is that climate impacts are way worse than we predicted.
