According to a Reuter's article, "Putin told an international climate conference that warmer temperatures would mean Russians "spend less on fur coats" while "agricultural specialists say our grain production will increase, and thank God for that".
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.
It fits his actions, and so I assume he really believes it and is acting on it. As I said above, he is an authoritarian leader, and so what the government actually does may be very different than the laws and policies it presents to the public.
