From 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.
