Russia and Kyoto -another U-turn?

After sending signals that seemed to indicate that ratifying the Kyoto agreement wasn't in Russia's interests, it may be that they will do it after all.... read about it; it may be that all the shilly-shallying is about extracting as many concessions favourable to Russia as they can before ratifying. The effect would be to convert the protocol into an international treaty and isolate USAmerica , apparently.
