Climate change is one of the biggest issues of our time that will hopefully become a hot presidential election topic. At the Democratic National Convention, actress Sigourney Weaver introduced a video directed by James Cameron that contrasts the opposing views of Hillary Clinton and Donald Trump on climate change. Titled "Not Reality TV," the video includes clips of the forthcoming season of Years of Living Dangerously, a show that will air on the National Geographic Channel. https://www.youtube.com/watch?v=_wJJk-kVjWg The five and a half minute video reveals how climate change affects everything from hurricanes to agriculture to fires to drought.
