Four hundred years ago, from 1610 to 1633, the Roman Catholic Church thought it knew more about the solar system than Galileo Galilei. So it subjected Galileo to an Inquisition.
Now, in 2015, Pope Francis thinks he knows more about climate science than thousands of educated climate scientists (like me). So the Pope wants a new Inquisition for those who tell you the truth about climate change.
The fallible Pope Frances "believes" global warming is "mainly" man-made. He believes the Paris summit must implement a Global Warming treaty or our environment is toast. He believes global warming hurts the poor.
He's wrong on all counts. The loss of carbon-dioxide-restricted abundant cheap energy, not global warming, hurts the poor.
Although the Catholic Church does not claim the Pope is "infallible" in matters of science, few people understand this technicality. So the Pope, with his great influence, does great damage to truth with his false claims about science.
