Fred--That depends on the proposed POTENTIAL specific objective (that is, this is all pretty speculative with little supporting research to date)---slow Arctic warming, moderate potential for very intense hurricanes, nudge storm tracks, cooling waters reaching glacial calving faces, etc. We don’t know that any are possible, but all seem to depend on energy patterns, timing, gradients, etc. that might be able to be modified by cloud brightening, cirrus thinning, water/surface brightening, vertical mixing of the water column, disruption of the insulating effect of sea ice, and other approaches that might possibly be altered in their spatial extent, intensity, and influence. Note, however, that this all assumes a good bit of mitigation is going onto stop making the situation worse—without that, on the course we are on, such specific regional/sectoral approaches, even if they might work in plausible ways, would be quickly overwhelmed and so not really worth doing.

However, we should be entirely clear: There is absolutely no evidence that any US intelligence agency has any interest in climate intervention for anything other than defense-related informational purposes. Furthermore, there is no plausible scenario in which climate intervention could be used effectively as a weapon. So, while I share Alan's contempt for the criminal behavior of our secretive governmental agencies, I do not think it is helpful to speculate that in this instance, the agencies are looking for new ways that they might inflict suffering on others.
