Are there any phrases in today’s political lexicon more obnoxious than “the science is settled” and “climate-change deniers”?
The first is an oxymoron. By definition, science is never settled. It is always subject to change in the light of new evidence. The second phrase is nothing but an ad hominem attack, meant to evoke “Holocaust deniers,” those people who maintain that the Nazi Holocaust is a fiction, ignoring the overwhelming, incontestable evidence that it is a historical fact. Hillary Clinton’s speech about climate change on Monday in Des Moines, Iowa, included an attack on “deniers.”
