Public discussion of scientific topics such as global warming is confused by misuse of the term “skeptic.” The Nov 10, 2014, New York Times article

“Republicans Vow to Fight EPA and Approve Keystone Pipeline” referred to Sen. James Inhofe as “a prominent skeptic of climate change.” Two days later Scott Horsley of NPR’s Morning Edition called him “one of the leading climate change deniers in Congress.” These are not equivalent statements.

As Fellows of the Committee for Skeptical Inquiry, we are concerned that the words “skeptic” and “denier” have been conflated by the popular media. Proper

skepticism promotes scientific inquiry, critical investigation, and the use of reason in examining controversial and extraordinary claims. It is

foundational to the scientific method. Denial, on the other hand, is the a priori rejection of ideas without objective consideration.

Real skepticism is summed up by a quote popularized by Carl Sagan, “Extraordinary claims require extraordinary evidence.” Inhofe’s belief that global

warming is “the greatest hoax ever perpetrated on the American people” is an extraordinary claim indeed. He has never been able to provide evidence for

this vast alleged conspiracy. That alone should disqualify him from using the title “skeptic.”

As scientific skeptics, we are well aware of political efforts to undermine climate science by those who deny reality but do not engage in scientific

research or consider evidence that their deeply held opinions are wrong. The most appropriate word to describe the behavior of those individuals is

“denial.” Not all individuals who call themselves climate change skeptics are deniers. But virtually all deniers have falsely branded themselves as

skeptics. By perpetrating this misnomer, journalists have granted undeserved credibility to those who reject science and scientific inquiry.

We are skeptics who have devoted much of our careers to practicing and promoting scientific skepticism. We ask that journalists use more care when

reporting on those who reject climate science, and hold to the principles of truth in labeling. Please stop using the word “skeptic” to describe deniers.
