^Dunlap 2013. Climate Change Skepticism and Denial: An Introduction. : 691－698. There is debate over which term is most appropriate… Those involved in challenging climate science label themselves "skeptics"… Yet skepticism is…a common characteristic of scientists, making it inappropriate to allow those who deny AGW to don the mantle of skeptics…It seems best to think of skepticism-denial as a continuum, with some individuals (and interest groups) holding a skeptical view of AGW…and others in complete denial

Using the language of denialism brings a moralistic tone into the climate change debate that we would do well to avoid. Further, labeling views as denialist has the potential to inappropriately link such views with Holocaust denial… However, skepticism forms an integral part of the scientific method and thus the term is frequently misapplied in such phrases as "climate change skeptic".
^Jacques, Dunlap & Freeman 2008. The organisation of denial: Conservative think tanks and environmental scepticism. : 351. Conservative think tanks…and their backers launched a full-scale counter-movement… We suggest that this counter-movement has been central to the reversal of US support for environmental protection, both domestically and internationally. Its major tactic has been disputing the seriousness of environmental problems and undermining environmental science by promoting what we term 'environmental scepticism
