Sure we been messing with nature,but not to where we try and change entire weather patterns,and beside if the mayor of Moscow thinks he can change entire weather patterns with a couple of plans.He severely doubts the power of nature. Weather changes so fast, I doubt he can stop a surprise...

I don`t think we should be messing with Nature.Not to mention there has not been much study into the effects this possible will have.
