As a bishop who regularly preaches to congregations of every age and at widely different levels of prosperity and education, I have some grasp of the challenges in presenting a point of view to the general public. This helps me to understand the propaganda achievements of the climate extremists, at least until their attempted elimination of the Medieval Warming and then Climategate. I was not surprised to learn that the IPCC used some of the world's best advertising agencies to generate maximum effect among the public.
In the 1990s we were warned of the "greenhouse effect," but in the first decade of the new millennium "global warming" stopped. The next retreat was to the concept of "anthropogenic global warming"; then we were called to cope with the challenge of "climate change." Then it became apparent that the climate is changing no more now than it has in the past. Seamlessly, the claim shifted to "anthropogenic climate disruption."
My suspicions have been deepened over the years by the climate movement's totalitarian approach to opposing views, their demonizing of successful opponents and their opposition to the publication of opposing views even in scientific journals. A point to be noted in this movement's struggle to convince public opinion is that their language veers toward that of primitive religious controversy. Believers are contrasted with deniers, doubters and skeptics.
