I note the use of cloud seeding by the Chinese, and its unexpected effect in causing huge snowfalls in Beijing. It seems that there may be two useful geoengineering approaches with this technique, and I'd be interested in hearing comments.
1) Rebuild ice - by inducing snowfalls over Greenland, Antarctica and the Arctic, it would perhaps be possible to maintain ice. In Greenland, where the height of the ice cap is critical, this would seem a particularly appealing prospect. 2) Albedo modification - Fresh snow is whiter than old snow, especially in polluted areas. Is the albedo change worth pursuing? My guess is not. HOWEVER, I suspect that triggering significant autumn and spring snowfalls in permafrost regions, we could potentially significantly modify albedo. I invite comments.
