Hello, I didn't know about "Make sunsets". They claim on their web site: Specifically: we release a natural compound via reusable balloons to create reflective clouds in the stratosphere. They're * really* effective: 1 gram of our clouds offsets the warming that 1 ton of CO ₂ emissions

I had read from the research information that in a chemical and size sense the spheres could be thought of as sand, just shaped to be highly reflective. But the question of whether they float is a good one. Peter *From:* geoengineering@googlegroups.com *On Behalf Of *Andrew Lockley *Sent:*

“ For now, opponents won’t back down. To Biermann, solar geoengineering should be considered by governments as being akin to landmines or biological weapons and blacklisted internationally. “This is just another one on this list,” he said. “People talk about the freedom of research, but you

Hi All The Hoffmann paper seems to be a convincing argument to treat regions where there has just been rain to clean the air and to use a mono-disperse spray to get a high nucleation fraction. We do not want the bigger nuclei to grab water vapour and starve the smaller ones. Advice on the
