I thought this was interesting, but also nuts. I dont think we should be trying to change nature directly more than we already do. Check it out though. Heres part of the article and the link as well.

Yuri Luzhkov has said that snow should be banished from Moscow in winter to save money and improve life in the city. He claimed that farmers outside the capital would enjoy more abundant harvests if his cloud-seeding programme was adopted.

Mr Luzhkov noted that city authorities already used such techniques to break up rain clouds and guarantee good weather on important public holidays, such as the annual May 9 parade celebrating victory in the Second World War. “Why don’t we keep this snow outside the Moscow city limits?” he said. “For the countryside, this means more moisture and bigger harvests. And for us, less snow.”
