This article published this morning by David Keith and Wake Smith argues that it is entirely feasible that SAI could begin to be deployed at small scale within five years by launching aerosols at higher latitudes where the lower stratospheric boundary is easily accessible by current aircraft.
It appears that their proposal is consistent with what Mike Maccracken has long been advocating - start small and learn by doing testing. They also argue that such testing should be subject to a formal moratorium - absent the development of a viable governance structure - consistent with the recommendations of the Climate Overshoot Commission. The risks of igniting a geopolitical free for all, particularly if testing were only done by one country and not by a coalition, are substantial they argue. Is this proposal something that those on these lists should get behind?
