Are you saying that Putin's true beliefs are quite different, and that he has long believed that anthropogenic climate change is occurring, and it is a threat to Russia? And if so, do you have any evidence from more than a couple years back?

Let me add that Obama has long be quite concerned about GCC, and he has made this quite clear in numerous public speeches for many years. He has done this because he wants the US public and the world to know where he stands.

If Putin was likewise concerned, then you would expect him to make this similarly clear, and it would be easy to come up with quotes over many years on the web.
