Hi everyone, I am finalizing a chapter on geoengineering policy for publication and would greatly appreciate informed feedback on the following paragraph:
"The aerosol most commonly suggested for stratospheric injection is sulfuric acid. Plans call for delivering sulfate aerosols by dispersing gas-phase precursor materials. Precursor oxidation and aerosol formation involve complex processes with the potential to reduce the effectiveness of stratospheric insertion. For instance, coagulation could lead to excessively large sulfuric acid particles that sediment out of the stratosphere, neutralizing the effect of the initial dispersion. Multiple, independent injections would increase the likelihood of such unintended consequences. Unsynchronized staging, scheduling, and delivery of sulfate aerosol injections would magnify the potential for perverse particulate interactions, and might jeopardize the success of geoengineering deployment. Lack of policy coordination may result in separate injection schemes that effectively cancel each other out." For those with scientific/technical backgrounds, is this a sound argument? Is the basic science correct? I am outside my comfort zone with this and want to be sure I don't miss the mark. Thanks to anyone who can offer insight.
