| Since you're here, care to reply to the article? I'm curious how you are planning to validate that this works and doesn't have negative side-effects. > That’s in part because it’s highly controversial. Little is known about the real-world effect of such deliberate interventions at large scales, but they could have dangerous side effects. The impacts could also be worse in some regions than others, which could provoke geopolitical conflicts. [...] > By Iseman’s own description, the first two balloon launches were very rudimentary. He says they occurred in April somewhere in the state of Baja California, months before Make Sunsets was incorporated in October. Iseman says he pumped a few grams of sulfur dioxide into weather balloons and added what he estimated would be the right amount of helium to carry them into the stratosphere. > He expected they would burst under pressure at that altitude and release the particles. But it’s not clear whether that happened, where the balloons ended up, or what impact the particles had, because there was no monitoring equipment on board the balloons. Iseman also acknowledges that they did not seek any approvals from government authorities or scientific agencies, in Mexico or elsewhere, before the first two launches. |
Efficacy and the benefit:harm ratio is still to be determined until we scale up our deployments, but here is a lecture by David Keith, the leading researcher in stratospheric aerosol injection. Towards Quantitative Comparison of the Risks and Benefits of Solar Geoengineering (https://www.youtube.com/watch?v=NZ8TZqfwzdU&t=2247s)
TL;DW: it's 100:1 at conservative estimates.
