Sulfuric acid is one of the most well understood stratospheric nanoparticles because we have millions of years of geological data to correlate with the climate history. If you're worried about unintended consequences and models being insufficient for prediction, you want to be as conservative as possible with your nanoparticle choices. Terraforming is not something to treat lightly.
- DennisP 5y agoFrom the article: > Current man-made and natural ISA emissions total over 100,000 tonnes and have many beneficial climate effects. They're only talking about adding another 200,000. And... > By directly copying the main planetary cooling mechanism from the ice ages, ISA has at least twelve identified cooling effects, presenting a balanced natural process. So this also has geological history to draw on. Despite this, they're currently only proposing a small trial, to make sure of safety for more trials. I don't think they're treating anything lightly.
