I really enjoy Lawrence Krauss, and Richard Dawkins, and, alas, Christopher Hitchens etc. I am an "anti-theist" and someone who has absolutely no belief in god. That being said, I have spoken at my wfe's church, cooked for their dinners, and was friends with the last pastor. He and I accepted that we had no common ground in the spiritual world, but we both agreed that community is good, and that creating friends and being good friends and neighbours is good. How could that not be? I stood up in front of the church and said I was an Atheist and that I enjoyed the community. I got applause. This is a true story.
Lawrence, Richard, an others obviously need to continue the Atheism work that they do, but they also need to understand that this was a HUGE movement by the catholic church. HUGE. The pope is a chemist. A scientist. If you judge this pope by his words and his actions, he may be the sort of man that can lead a sizeable portion of the world population in a better direction.
I think "Atheism" and "Climate Change" are separate. If this pope did not do enough, reach out. He isn't the nazi-youth that was there previously, this is a man trained in chemistry and seems earnest. I think this is the best chance science and a major religion have ever had to work together to address a real problem facing human kind. Rather than snipe at the pope for not going far enough, holy shit guys, 1 billion people claim to listen to this guy, convince him to do better.
