Last week environmentalists and their allies led a series of actions to pressure politicians to make significant commitments on climate change, ahead of the United Nations Climate Summit. The key event, the People’s Climate March in New York City, drew an estimated 400,000 people, among them UN Secretary-General Ban Ki-moon, former Vice President Al Gore and Leonardo DiCaprio. This unprecedented public call to action did not seem to make much of an impact on Republicans, however. On Friday, conservatives gathered at the Values Voter Summit in Washington, DC, and were dismissive of any threat from climate change, to say the least. Watch them in all their climate-denying glory.
