The terminology is debated: most of those actively rejecting the scientific consensus use the terms "skeptic" and "climate change skepticism", and only a few have expressed preference for being described as deniers, but the word "skepticism" is incorrectly used, as scientific skepticism is an intrinsic part of scientific methodology. The term "contrarian" is more specific, but used less frequently. In academic literature and journalism, the terms "climate change denial" and "climate change deniers" have well-established usage as descriptive terms without any pejorative intent. Both the National Center for Science Education and historian Spencer R. Weart recognize that either option is problematic, but have decided to use "climate change denial" rather than "skepticism".
