Neil deGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History, started a campaign to “Make America Smart Again” after Trump won the election in November.

In a new video posted on his Facebook page, Tyson argues that intelligent policy discussions can only happen once we accept that science is the emergent truth. “This is science. It’s not something to toy with. It’s not something to say, ‘I chose not to believe E=mc2.’ You don’t have that option. When you have an established scientific emergent truth, it is true whether or not you believe in it. And the sooner you understand that, the faster we can get on with the political conversations about how to solve the problems that face us.” Tyson exemplifies these thoughts through a discussion of climate change. He argues that political discussions about climate change policy, such as carbon tax credits or tariffs, can only happen once the science of climate change is embraced.

How we get to a common emergent truth, within our current political structure, is the problem. Vice President Mike Pence is featured in Tyson’s video rejecting the science of evolution. “Let us demand that educators around America teach evolution as fact and not as theory.”

Pence, like Trump, many who surround Trump, and key chairmen of the House and Senate committees are climate change deniers. The chairman of the House Committee on Science, Space and Technology, Rep. Lamar Smith (R-TX), recently went so far as to challenge the credibility of Science magazine by saying, “That is not known as an objective writer or magazine.” Smith’s comment followed the testimony of Michael Mann, a climate scientist at Pennsylvania State University. Mann had cited an article in Science magazine written by Jeffrey Mervis. The article covered a conference for global warming skeptics. In that article, Mervis called out Smith, who attended the skeptics’ conference, for using his House committee as a “tool to advance his political agenda rather than a forum to examine important issues facing the U.S. research community.” Hence, Smith challenged the credibility of the magazine and writer.

Just to be clear, the American Association for the Advancement of Science publishes Science magazine.
