From Matt Ridley and Benny Peiser  at The Wall Street Journal, Your Complete Guide to the Climate Debate;

To put it bluntly, climate change and its likely impact are proving slower and less harmful than we feared, while decarbonization of the economy is proving more painful and costly than we hoped. The mood in Paris will be one of furious pessimism among the well-funded NGOs that will attend the summit in large numbers: Decarbonization, on which they have set their hearts, is not happening, and they dare not mention the reassuring news from science lest it threaten their budgets.

Casting around for somebody to blame, they have fastened on foot-dragging fossil-fuel companies and those who make skeptical observations, however well-founded, about the likelihood of dangerous climate change. Scientific skeptics are now routinely censored, or threatened with prosecution. One recent survey by Rasmussen Reports shows that 27% of Democrats in the U.S. are in favor of prosecuting climate skeptics. This is the mentality of religious fanaticism, not scientific debate.
