Climate change is one of the biggest issues of our time – and it should be a hot topic in this year’s presidential election. 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 reveals how climate change affects everything from hurricanes to agriculture to fires to drought.

The five and a half minute video includes clips of the forthcoming season of Years of Living Dangerously, a show that will air on the National Geographic Channel. It includes input from celebrities like Arnold Schwarzenegger, Don Cheadle, Jack Black, and America Ferrera, who spoke with people already impacted by global warming or fighting against global warming.

“When we talk about greenhouse gases and warming temperatures, or deadlier droughts, even more destructive storms, what we’re really talking about is people,” Weaver said in her introduction. The video shares brief clips of a Texas rancher whose cows have little to eat, a Kansas farmer whose crops aren’t getting enough rain, and a New York mother who lost her daughter in Hurricane Sandy. “Can Donald Trump look these people in the eye and tell them climate change is a hoax?” asked Weaver.

The video appeared to reach across the aisle to conservatives, including a clip of George H. W. Bush who said, “human activities are changing the atmosphere,” and a clip of conservative Christian pastor Andrew Farley who said, “I believe climate change is real.”

The video included clips of Donald Trump denying climate change, referring to it as a “hoax,” and saying he’ll cancel the Paris agreement. In contrast, in the video Hillary Clinton states America can become “the world’s clean energy superpower.” Her stance in the video centers around renewable energy; she speaks of how the “half a billion solar panels across the country in the next four years” together with other forms of renewable energy can power America’s homes. She speaks also of the jobs that will be created by pursuing clean energy.
