How hard is it to say exactly what you mean?

I am not confident that I know whether the Pope or the Vatican is in favor of carbon pricing policies or opposed. I read the encyclical as being opposed, for exactly the same reasons that Stavins and Nordhaus did. Now Joe Romm says we got it all wrong. The fact that very smart people can disagree on such a straightforward question suggests that the encyclical, in this regard, was poorly written, or perhaps poorly translated. Now there is a simple solution: Francis, do you or do you not support cap-and-trade and or carbon taxes as key policy instruments for combatting global warming?
