AGW is a modern day religion complete with dogma (reduction targets, solar/wind) and rituals (indulgences a.k.a carbon offsets). I would love to have a discussion with people who actually care about the science instead of proselytizing but they are few and far between.
Around 93% of climate scientists agree that AGW is occurring so you shouldn't have trouble finding one. The main difference between the experts is how fast it is happening.
