Jan Wasilewsky Michael Rorer Consider the apt metaphor "Spaceship Earth" and what that implies for geoengineering. Air-conditioning one's home planet is in principle no different from air-conditioning one's home...

Gernot Wagner's "never ever" position appears absurd to me on many grounds. We are changing the world around us just by living in it - as do ants and worms, except that we progress faster. As we progress, we change the world on a growing and accelerating scale - and that, too, is (I hold ) inevitable. Geoengineering merely means: doing more intelligently what we will do anyway. It means making rational choices. Of course, every choice we make in life has both positive and negative consequences (considerations on droughts and hurricanes are samples). It is not a tenable argument for refusing to make choices: that, too, would be a choice. We must balance the consequences as best we can. The weakness of our capacity to predict implies that we must both predict and *experiment*, combining theory and practice. It is not an argument for delay: just the opposite. The sooner we begin - the faster we will gain experience - the wiser choices we'll make later.
