When chilling cold first descended in early January, we had an occasion to correct Donald Trump on climate science. To do so, we simply explained that the widely recognized phenomenon known as winter doesn’t refute global warming, especially since winter is inherently limited to one hemisphere. (In a widely lampooned tweet, Trump had cited “record low temps” in arguing that “this very expensive GLOBAL WARMING bullshit has got to stop.”)

Alas, Trump has now dug himself deeper into the snow drift. Here are the latest tweets:

With this, Trump joins the grand tradition of climate science conspiracy theorizing, as epitomized by Sen. James Inhofe’s (R-Okla.) 2012 book title: The Greatest Hoax: How the Global Warming Conspiracy Threatens Your Future. By using the word “hoax,” Inhofe and Trump are suggesting that there is a conscious attempt to mislead us with fake, trumped up science, in the service of political goals.
