Former President Bill Clinton has some tough words for Republican climate-change deniers: quit making the U.S. "look like a joke."
Kicking off his Clinton Global Initiative in New York, the former president said Americans should make it "politically unacceptable" for people to engage in climate change denial, according to Politico.
"I mean, it makes us -- we look like a joke, right?" Clinton said. "You can't win the nomination of one of the major parties in the country if you admit that scientists are right?"
Clinton's three-day conference -- held in New York at the same time as the United Nations' General Assembly -- comes a week after former Vice President Al Gore called out climate change deniers. Gore, at a climate event in New York, said that carbon polluters are the "biggest source of campaign contribution," which he said surely influences politicians.
