An article has been making the rounds recently about scientists at Harvard being fairly certain that aerosolic geoengineering approaches would be able to reduce the GHG effect by 50% or more, and in fact do so in a way that not only cools the planet, but does so in a way to ensure that we get the benefits of a little warming. These guys seem to think that this can be done rather cheaply.
I am SURE zillions of pople are going to say NO WAY. Let me ask the hypothetical question: what does this say about your beliefs about the catastrophic damages of climate change if you say that “geonengineering solutions are too risky?”
