In “Climate Engineering Reconsidered”, Barrett et al. discuss the effectiveness and the political feasibility of geoengineering as either an emergency measure or a stop-gap. After considering various hypothetical applications, such as staving off an altered monsoon, the authors conclude: “when the use of geoengineering is politically feasible, the intervention may not be effective; and that, when the use of geoengineering might be effective, its deployment may not be politically feasible,” (527). In other words, it’s time to find Plan B.
What’s interesting about this article, though, is that the authors are quick to emphasize that geoengineering – which, used in this context, consists of injecting sun-scattering sulphate aerosols into the stratosphere (Solar Radiation Management, or SRM) – is Plan B, and that our best course of action is still Plan A: good old-fashioned adaptation. While not as technologically impressive as geoengineering, adaptation avoids many of the challenges posed by the more advanced option, namely dependency/addiction and the introduction of unknown side effects. Barrett et al. also mention the risk of politicization of geoengineering, in which countries could threaten economic or military action, or even the use of “counter-geoengineering”, in order to control how other nations employ the technology. In lieu of working together to fix a shared problem, we would be introducing a new source of conflict.
Not to trivialize the matter, but in my opinion, remedying climate change need not become this complicated. Although it is a complex issue, we have a fairly good understanding of what we’ve been doing wrong and what can be done to make it right – or, at least, better. Barrett et al. believe that “contemplation of geoengineering does little to diminish the need to address the root causes of climate change”, and that, if anything, it should strengthen our resolve to make less technologically-involved changes. Perhaps our insistence on finding “easier” ways to fix the problem of climate change is indicative of our inability to do the hard, day-to-day work of cutting energy consumption and reducing emissions. Usually we resort to Plan B when Plan A has failed us, but, in this case, it’s not clear that we’ve given Plan A its fair shot.
Do you think Plan A (adaptation) is simply a lost cause? Even though geoengineering does not present a feasible long-term solution, are the possible short-term benefits (specifically, in the stop-gap scenario) enough to continuing exploring the option? Finally, given what we know about today’s political climate, is either option politically feasible on an international level? — Tomi
