The prevailing narrative by members of the climate establishment is the assertion that the science is settled. This is a tactic to stifle debate and informed discussion. Anyone who challenges the narrative is subject to pejorative characterizations — denier, skeptic.

What these advocates avoid discussing is the fact that science is never settled. Newton’s theory of gravity was replaced after almost 300 years by Einstein’s theory of relativity in the early 1900s. Scientists are still trying to identify its limits and extend it. An article in Physics Today stated, “Einstein’s gravity will never be proven wrong by a theory. It will be proven wrong by experimental evidence showing that the predictions of general relativity don’t work.” That is an important statement about all science.
