(Washington Post) Give Donald Trump credit for consistency. The Republican presidential front-runner repeatedly has said he isn't "a believer" that humans have played a significant role in the Earth's changing climate. He said as much in an interview with talk show host Hugh Hewitt last year. He told "Fox & Friends" earlier this year that climate change "is just a very, very expensive form of tax. A lot of people are making a lot of money."
In his own tweets, Trump has called the concept of global warming everything from a "hoax" to "bulls—" to a scheme "created by and for the Chinese in order to make U.S. manufacturing non-competitive." (He later said he was joking about the China tweet).
