The people who appointed him UN special envoy for climate action probably thought he was a climate guy. The people who read his book (not me) seemed to think he was a climate guy. The people who believed his election campaign promises might've thought he was a climate guy. He probably still thinks he's a climate guy.

He talks a lot about the importance of climate change, so it comes as a surprise to quite a few people that he doesn't seem to be in favour of doing anything about it.
