evidence: Whatever terms Trump might have in mind, of course, are secondary to the fact that the president doesn’t appear to believe in climate change at all. "There is a cooling and there is a heating, and I mean, look—it used to not be climate change. It used to be global warming. Right? . . . That wasn’t working too well, because it was getting too cold all over the place. The ice caps were going to melt, they were going to be gone by now, but now they’re setting records, so O.K., they’re at a record level." [...] The overwhelming majority of scientists disagree. Data released this month by the National Oceanic and Atmospheric Administration showed that 2017 was one of the hottest years on record. (The world’s oceans have never been hotter.) It’s also unclear what Trump’s comments about the ice caps referred to. The N.O.A.A.’s annual Arctic Report Card, published in December, found that the percentage of the Arctic Ocean that freezes over during the winter hit a record low in 2017, and is declining faster than at any time in the past 1,500 years. NASA reported last year that sea ice at the South Pole also hit a record low due to melting.
