writes "Where can a reasonably educated layperson read the pro and con evidence for global warming? Maybe even with real data that can be understood by someone who remembers their college math and physics. I'm asked all the time by friends and relatives for my opinion on global warming, and I always hesitate to answer. Yes it seems like far more 'experts' believe it is real than not, but I don't want to just parrot the words of someone else. I'd like to try to decide for myself. Everything I have read is either far too simple, or written for atmospheric scientists, or so clearly approaching the evidence with a strong pre-existing bias. Isn't there anyone who, like me, hasn't made up their mind and has reviewed and presented the evidence before coming to a conclusion?"
