Ulan Bator, the capital of Mongolia, is considering creating extra ice in winter.
A Mongolian engineering firm ECOS & EMI aims to drill bore holes into ice formed on the Tuul river in winter. The water will be discharged across the surface, where it will freeze. This process - effectively adding layers of ice rinks - will be repeated at regular intervals throughout the winter.
The idea is that this can help cool and water the city as the ice melts during the summer.

Given the immense amount of geoengineering literature now available, I have yet to see a proposal for space based nuclear detonations as a means for solar radiation reduction. Roger Angels idea inevitably uses thick material - why wouldn't atomized aluminum from small nuclear explosions launched via ICBM type missiles be cheaper and more effective?
Sounds like that would be pretty much undoable. I don't like the idea of conducting a global scale experiment which can't be reversed in timescales that are relevant to human beings.
