evidence: "You know, when I hear these poor fools talking about global warming, they don’t call it that anymore, they call it climate change because, you know, some parts of the planet are cooling and warming. It didn’t work," he told Ryan, referring to the term. "So they finally got it right … they just call it climate change. They used to call it global warming." [...] The suggestion is clear: If scientists were wrong about the climate before, then they could be wrong about it now. But it’s a myth that there was a scientific consensus about "global cooling" before. And even if some scientists did once think that cooling might be coming, it would not change the current reality — based on a significant body of evidence — that global warming is happening. [...] University of Pennsylvania climate scientist Michael Mann told us Trump "simply mangled the shop-worn, untruthful climate denier talking point" that scientists were predicting global cooling in the 1970s. "[T]hey weren’t," he said.
