Andrew Revkin has a fascinating post on scientific communication where he admits to being a "recovering denialist."
No, not of climate change. Instead, Revkin was in denial about the influence of scientific communication. He writes:
"My denial, I said, lay in my longstanding presumption, like that of many scientists and journalists, that better communication of information will tend to change people’s perceptions, priorities and behavior. This attitude, in my view, crested for climate scientists in the wake of the 2007 report from the Intergovernmental Panel on Climate Change."
