  • Of those, [9] seems the most obviously relevant, although it covers more techniques than just SAI. One particularly relevant passage from [9] reads:

    … materials lofted this high and staying in the atmosphere for extended periods tend to spread out to cover the globe. As a result, both their climatic influences and any unintended side effects (e.g., increased scattering of incoming solar radiation that diminishes the efficiency of direct-beam solar energy technologies) tend to be global in extent.

    Since [9] is focused on discussing regionally-targeted geoengineering techniques, the presumed global spread of SAI is here being mentioned mainly as a potential disadvantage.

    I think Jones et al. are actually raising two concerns with their work:

    1. Unilaterally deployed SIA targeted at a particular region could have negative side-effects. This is the topic most relevant to your question. As the references show, there were indeed plans for this, at least in the sense that it had been discussed in the literature for some years. I don't know of any state drawing up concrete plans for SIA stations yet, but it's probably a good idea to raise these concerns before the policy train gets rolling.

    2. SIA might be deployed at a single site as a globally targeted SG technique, with the assumption (as seen in [9]) that it doesn't matter where you do it because the aerosols will spread evenly over the globe in any case. Jones et al. show that this will not necessarily happen.
