If there is already a consensus in the scientific community around climate change, will 2012 see a political consensus emerge? With a presidential election this year, that's not very likely.
However, there are positive signs.
Take sometime skeptic Richard Muller, who completed a Koch brothers-funded study and concluded there is overwhelming evidence for climate change. Author James Lawrence Powell describes the curious case of Muller and what it means to the climate change debate in an interview with Big Think here.
But why are so many people so steadfast in their beliefs? Big Think blogger David Ropeik has written on this site extensively about the phenomenon of Cultural Cognition, which "describes the way we shape our views so they support and confirm the views of the groups with which we most strongly identify." Ropeik identifies climate change science as a prime example here and here.
