I would consider this a first real step towards combating climate change, even tiny like this one, because everything else humans are doing is more of a greenwashing and corporate blame shifting, completely invisible in the resulting graphs over past years (temps and co2 levels). So to me it is the only viable path to do anything really (alternatives are a) sunshield, for which we don't have any requirement technologies, or b) seeding atmosphere with sulfur compounds, which we maybe can do, but with uncertain modelling today). Surprisingly, the comments on ArsTechnica are overwhelmingly negative, so I wonder, what do you think about this initiative?
