Reddit mentions of Dire Predictions: The Visual Guide to the Findings of the IPCC

That's an excellent idea, except for a couple of small points: Moscow is nowhere near the ocean. So to get that snow to the ocean would create a carbon footprint that would cause more damage than the amount of amelioration the snow melting into the ocean would provide. And that brings me to the second point. The amount of snow in Moscow is very small compared to the vastness of the ocean. It would probably not help "combat" rising sea temps overall, but it would lower the temp of the water where they dumped the snow in for sure. If you would like to learn about climate change from a respected professional, let me suggest Michael E. Mann. Have a great day and keep up that thinking stuff!
