(Reuters) - U.S. President-elect Donald Trump said on Tuesday he thinks there is some connection between climate change and human activity and “clean air is vitally important,” a New York Times reporter said in a tweet. Trump, who met Times reporters and editors in New York, “says he is keeping ‘an open mind’” on the issue, the Times’ reporter wrote on Twitter.  Trump has previously called man-made global warming a hoax. “I think there is some connectivity” between humans and climate change, Trump said in the Times interview.
