The so-called debate about the causes and effects of anthropogenic global warming (AGW) is a notable irony. Rather than a forum for free disputation, AGW has in recent years become the site of a consensus equating majority opinion with truth—leaving little, if any, room for debate. After all, doesn’t everyone but a misguided few agree that we are in the grip of an unparalleled, man- made climatic catastrophe?

“You can say I don’t believe in gravity. But if you step off the cliff you are going down. So we can say I don’t believe climate is changing, but it is based on science.” – Katherine Hayhoe, co-author of the 4th National Climate Assessment Report.

In our view, the fact that so many scientists agree so closely about the [causes of the] earth’s warming is, itself, evidence of a lack of evidence for [human caused] global warming. – D. Ryan Brumberg and Matthew Brumberg

Acknowledging the science of global warming does not require accepting that it is immune to criticism.

At the Senate Hearing on “Dogma and Data”, dogma about the 97% consensus went unchallenged. Democratic Senators constantly recited the phrase “97% consensus”, but it is not clear whether they – or their Republican opponents – had the slightest idea what the phrase meant: 97% of what group support a consensus about exactly what?

A frequent topic at Climate Etc. is the ‘consensus.’ An argument is presented here that the climate consensus is as much about culture as it is about climate science.

Any attempt to impose agreement will “promote confusion between consensus and certainty”. The goal should be to quantify uncertainty, not to remove it from the decision process. – Willy Aspinall

Among the best indirect indicators available to nonexperts is the overwhelming numbers of scientists testifying to anthropogenic climate change. Yet the evidential significance of such clear numbers turns substantially on our nonexpert assessment of these scientists’ trustworthiness. Absent trust, even without active distrust, the numbers’ evidential weight drops considerably. – Ben Almassi

Lewandowsky and Oreskes raise the prospect that via the agency of memes, the climate Consensus with its high certainty of danger, could be a socially generated artifact and not a scientific fact.

If deference to the authoritative opinions of experts is essential to our rationality and knowledge, and if that deference unavoidably rests on trust, not only in the competence, but also in the epistemic and ethical characters of our experts–then it is high time that we get to work on the ethics of expertise. Indeed, it is past time. – John Hardwig

Climate psychologists have for years now puzzled over public inaction on climate change and also what makes skeptics tick (or sick), apparently making little progress on these issues.
