The epithet “climate denier,” intended to invoke Holocaust denial, has always been tasteless and inapt. Climate change is not like the Holocaust, nor is questioning the accuracy and predictive power of a scientific model like questioning the historical fact of a genocide that murdered 6 million Jews.
But climate activists delighted in defining their opposition this way, with help from prominent figures such as Barack Obama, who in 2014 used Twitter to condemn “climate change deniers” and promote a website, run by Organizing for Action (formerly Obama for America), that featured large black-and-white pictures of then‚ÄìHouse speaker John Boehner and Senator Marco Rubio atop a green “Climate Change Deniers” banner. “On climate,” asked the site’s headline, “whose side are you on?”
For a while, this seemed to work. Framing the climate debate as one between noble keepers of the scientific flame and people akin to Nazis gave the former group license to say almost anything. To the casual observer, even the most egregious exaggeration about climate science could seem reasonable compared with its outright rejection. Thus, Obama’s assertion in his 2015 State of the Union address that “no challenge — no challenge — poses a greater threat to future generations than climate change” became widely accepted.
