ESD - The global climate response to High-Latitude Low-Altitude Stratospheric Aerosol Injection (HiLLA-SAI)

[H simmens]



This paper, just published today concludes that high latitude low altitude SAI would induce some degree of cooling - not as much as high altitude SAI - and its impacts would be global and not just polar.

I start as an SAI moderate, not an advocate, not an opponent.  I want to see the economic, environmental and political effectiveness of all competing cooling schemes, some of which are my own schemes.

If spring/summer sulfur is first approved for the Southern Hemisphere only for health reasons, will most of the deposition of sulfur stay out of the heavily populated Northen Hemisphere?

Sulfur has traditionally been raised over the Atlantic Ocean through thermals rising from ships.  Is there a reason to use more expensive airplanes?  If a number of Southern Hemisphere fishing ships were directed to burn high-sulfur fuel, would that help to cheaply solve the distribution problem?

Is much of the thrust of this paper applicable to less controversial sea salt microparticles or to some Israeli venture's microparticle X?

Yours in Hope,
