People can be decieved and the Pope is a person. He wasn't speaking ex cathedra so you can disagree with his conclusions and still be Catholic. I'm skeptical of climate change too but it doesn't change my allegiance to the church one bit.
Most based mean joining the climate change hoax?

From what I understand, Catholicism (Roman Catholicism) is the state sanctioned version of Christianity. Thoughts on this?
By what state? The vatican? Then yeah the Pope is the head of the vatican state and of the Catholic Church. Roman Catholicism is one rite but there are others like byzantine catholics which submit to the Pope but preserve eastern theology and tradition.
