Australian Cardinal George Pell?
“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. The immense financial costs true believers would impose on economies can be compared with the sacrifices offered traditionally in religion, and the sale of carbon credits with the pre-Reformation practice of selling indulgences. Some of those campaigning to save the planet are not merely zealous but zealots.” — Cardinal George Pell: One Christian Perspective On Climate Change, The 2011 Annual GWPF Lecture.
