As a philosopher working on this issue, it seems to me that this provides a really strong argument in favor of focused attention on mitigation. There's at least some degree of popular perception that geoengineering provides a "fail safe" for fixing the climate if/when we fail to successfully implement sufficient mitigation policies. In some cases, this leads to more lukewarm (or downright cold) support for mitigation than it otherwise would have. Philosophers and social scientists call this a "moral hazard."
But it seems to me that this position isn't just wrong--it's exactly backward. If a failure to adequately mitigate climate change means that our only recourse will be geoengineering, that's a *very* strong reason to mitigate early and mitigate often. The costs associated with geoengineering--both in terms of financial commitments and in terms of potentially dangerous side-effects--are just too numerous for it to be reasonable to think of a large-scale geoengineering program as a "fail safe." I think we would do well to work harder to promulgate that message more widely and more forcefully than we do now.
