Wired.com has a photo essay up on how we are already geoengineering the earth, which should prompt the valid question of if it’s acceptable to people to allow the existing geo-hacks go on, at least in the mainstream, why are people so wound up about geo-hacking to prevent climate change?

However, we should note that none of the we currently do under as geo-engineering here is a smart thing to do. So? One does not legitimize the other; it is instead big list of things we should knock off.
