New NASA chief and former Republican congressman Jim Bridenstine has had a change of mind (boldface mine):
NASA Administrator Jim Bridenstine, who previously questioned whether humans are primarily responsible for climate change, left no doubt Wednesday that his position has changed. Signifying a striking conversion, he confirmed that he now accepts that humans are, in fact, the leading cause.
During testimony before the Senate Appropriations subcommittee on commerce, justice, science and related agencies, Sen. Brian Schatz (D-Hawaii) asked Bridenstine whether he believes greenhouse gases are the primary cause of climate change. Bridenstine quickly replied in the affirmative.
“The National Climate Assessment, that includes NASA, and it includes the Department of Energy, and it includes NOAA, has clearly stated it is extremely likely, [that] is the language they use, that human activity is the dominant cause of global warming, and I have no reason to doubt the science that comes from that,” Bridenstine said.
Schatz followed up by asking, “Is it fair to call this an evolution of your views?”
Bridenstine replied: “Yes.”
…At his confirmation hearing before the Senate in November, Bridenstine’s responses to a similar line of questioning were much more nuanced and opaque. When asked whether human activity was the primary cause of climate change, he said, “It’s going to depend on a lot of factors, and we’re still learning more about that every day.”
…His evolved views are also notable for a former Republican congressman from Oklahoma. Research published in the journal Climatic Change in 2016 found just 31 percent of Republicans in Oklahoma (and nationwide) agreed that global warming is caused mostly by human activities.
While Democratic politicians can be bad, professional Republican contempt for their own base is pretty breathtaking.
