With Donald Trump’s recent picks to head the Environmental Protection Agency (Scott Pruitt) and the Energy Department (Rick Perry), it appears that science denialism has now been institutionalized. Pruitt, Perry, and Trump deny the fact that increasing levels of CO2 in the environment have trapped heat, causing an increase in the Earth’s surface temperature (“the greenhouse effect”), and consequent climate disruption. Although climate change is undeniable, the current administration has managed to deny it.
Climate change denialists couldn’t take their anti-science stance without the support of certain scientists. Although the overwhelming consensus among environmental scientists is that global warming is a real and present threat, a few disagree. Sadly, throughout history, science-denying scientists haven’t been hard to find.
In 1985, Barbara Loe Fisher, a prominent anti-vaccine activist, wrote A Shot in the Dark. In one chapter, Fisher claimed that vaccines caused autism. No one noticed. But when Andrew Wakefield, a respected scientist in the United Kingdom, published a paper in 1998 claiming that the measles-mumps-rubella (MMR) vaccine caused autism, everyone noticed. More than 1,500 articles trumpeting Wakefield’s theory appeared in newspapers and magazines across the globe. In the United Kingdom alone, thousands of parents stopped vaccinating their children with MMR; as a consequence, hundreds were hospitalized with measles and four children died from the disease.
