Hillary Clinton released a video on Monday mimicking a trailer for an old horror film — except instead of Frankenstein, the monsters were the Republican presidential candidates who deny that human-caused climate change is real.
Specifically, the video mocked candidates who have said “I’m not a scientist” when asked whether they accept the overwhelming scientific evidence that current global warming is primarily caused by carbon emissions. Jeb Bush, Scott Walker, Rick Perry, and Marco Rubio have all used the response, the video asserts.
The video then goes on to show clips of Republican candidates expressing doubt about climate science. “I do not believe that human activity is causing these dramatic changes,” Rubio says in the video. “There hasn’t been a noticeable change in recent times,” Walker says.
Using the phrase “I’m not a scientist” to respond to questions about climate change has been popular among many Republican politicians, not just those running for president. Climate scientists themselves have derided the tactic, noting that politicians are frequently presented with information curated by scientists to explain what’s going on with the climate. The National Climate Assessment, for example, was written by scientists and other experts specifically so that members of Congress could understand climate change and how it affects the country.
Of the climate scientists who actively publish research, 97 percent agree that humans are causing current global warming. The U.N. Intergovernmental Panel on Climate Change — which draws on the knowledge of almost 800 climate experts across the globe — says it is at least 95 percent likely that human activities are the main cause of atmospheric and ocean warming since the 1950s.
This is not the first time that Clinton, who is seeking the Democratic nomination for president, has spoken out against candidates who use the phrase. “I’m not a scientist either,” she said at a campaign event in Iowa on Sunday. “I’m just a grandmother with two eyes and a brain.”
