Thanks Paul, interesting write-up. I worry about the timelines given an impending recession from the Hormuz effect and the gradual, then accelerating GDP destruction as the planet warms. The event in two years time will be interesting to see if spirits have dampened.

I completely agree with your concern and have been trying to figure out my thoughts there because it would make for a good article. I think there’s not enough wrestling with the state and direction of geopolitics within this broader climate response conversation.

You’re right. I did an article recently on the timing window for SRM which also looked that the financial ability to carry it out given expected economic destruction through warming.

I’d be interested in co-writing something if you were?

I’d love to chat with you about that! I’ll send an email. And I appreciated the article you linked as well, I think it’s a great primer laying out the timeline hurdles.

Interestingly, our policy at GlobalCarbonReward.org also requires central bank participation. Perhaps the winds of change blow favorably..

Hi Paul, thanks. Ross Centers did a great interview about the Planetary Sunshade with Dan Miller at Climate Chat - https://www.youtube.com/watch?v=hlqBBRIETTk

I thought a key point was his argument that sunshades are competitive on cost with SAI over a long time frame.

I have an information thread about the Planetary Sunshade on an astronomy board on Space Exploration. I have shared this post there, at https://forum.cosmoquest.org/forum/science-and-space/space-exploration/3712034-planetary-sunshade?p=3754187#post3754187 Members there would likely be able to discuss astronomy and engineering issues.

And I liked your Bank of England governance analogy. I have suggested the Montreal Protocol as a governance model for an Albedo Accord, but there are lessons from a number of international organisations, such as the International Monetary Fund, the International Finance Corporation in the World Bank Group, and others. The history of the IPCC and COP does not inspire confidence in the UN system.
