I'm curious how much more evidence Pete (and fellow readers) need before they'd support SAI with sulfur dioxide to -.5C. Do we need to wait until AMOC actually collapses? First 1M+ dead in a wet bulb event? International governmental consensus?

We need several things:

- A robust, international assessment of the full range of consequences of a wise deployment of SAI, that after due consideration suggests that it could greatly reduce risks overall (if not necessarily universally).

- A legitimate process to arrive at a wise strategy for deploying SAI, and broad public and intergovernmental support for that strategy.

- An intergovernmental agreement to deploy SAI that also re-commits nations to cutting emissions and to supporting nations impacted by climate change and SAI to adapt to those changes.

- A practical means of deploying, i.e., a fleet of newly designed, high-altitude jets.

I fear that Make Sunsets does nothing to advance any of this and is likely to do more harm than good by undermining the legitimacy of the idea and encouraging nations to take a hostile position against the technology before a broad understanding of its potential benefits is widespread.

Is there a quantifiable reason you seem to reject Ken's modeling? https://makesunsets.com/blogs/news/optional-climate-change .

The world is literally burning while you wait for international consensus that may never come.

Last-generation military (MIG, etc.) + balloons are capable of deployment to -1C+ now.

Good luck with whatever action you think will actually advance deployment. Doesn't seem like hand-wringing is working so well. In the meantime, we'll continue deployments for any and all willing to pay.
