Campaigning in his home state of New York, GOP frontrunner Donald Trump exclaimed “it’s freezing, man” as he addressed supporters on a chilly, sub-40 degree day.

“It’s like record, record cold,” Trump said. “I keep hearing about global warming. Now they’ll say, ‘He doesn’t understand it. This is a worldwide problem.’ No, I don’t understand it. Let’s do IQ tests.”

Trump often points to current weather conditions as a means to mock concerns about climate change.
