Nice Interview. The good thing I remember is how people learned the word "albedo" after they made the news after the Mex. deployment. SAI has to be done with good ESG. cowboy style kills us Indians. Luke, if you read this, you did great getting the severity of global heating and the need for some sunlight reflection across.

This is a brilliant conversation. Thanks both. The challenge is to create demand by finding the constituencies of support who face commercial damage from a darker planet so they can fund advocacy

Hi Luke

You are and I tone-wise are exactly the same

Paul is great and often insightful but I've disagreed with him on SAI timelines on other posts.

I enjoyed this discussion and had heard of your company while doing research on Stratospheric Aerosol Injection start ups. Unfortunately regulation for limited tests is ok but not for the >34 million tons of SO2 we put up each year into the troposphere for profit.

That's another thread.

When I do my physical media work around Boston I often mention your company. On my end I've spent several months building an economic argument for the inevitability of SAI being used. Not should or shouldn't, will. If true, that would make SAI's problems merely something to tackle.

If they haven't already the developing world will have a December 7th moment. Their people just aren't having the dots properly connected between warming damage and the potential of SAI to slow sea level rise by decades and significantly decrease impacts from increased ocean surface temps. The rich world will make empty promises and slow walk the developing world to the gallows. America and friends just don't understand their own future damage yet: Locked in damage.

Locked in damage for just 2050 is, even if we achieve carbon neutral by that year, 19 trillion dollars minimum (19-51). And after a minimum 10 year warming lag (10-20 of continued ocean heat absorption) the true cap on annual damage/costs is best case 2060.

We know that is FAR too optimistic. That's why the rich world will use SAI themselves. China also an even more serious contender. It's SAI because the space mirror isn't logistically feasible before the rich world also becomes desperate.

I've built sai-reality.com to push this economic argument but regardless of you checking it out I want to say that, as silly as some people might think this statement is, your company is involved in the most important project the human species has ever undertaken.

What's great is that SAI will happen from self-interest one way or the other. We're just working to have it sooner to help more.

Thanks for reading!

Kevin
