In spite of the fact that Hollywood celebrities live in fancy houses, often use private planes and galavant around the world spewing far more carbon than the Average Joe, many of them love to warn about the threat of climate change.
So it was no surprise to see many film and music stars speaking out during the recent U.N. climate summit in Paris (COP21), which was held Nov. 30, through Dec. 12.
Using their star power, these five celebs particularly advocated for radical changes such as giving up cars and plastic bags, participated in a mock trial of ExxonMobil for the “Greatest Climate Crime of the Century,” rode on a Greenpeace float and lashed out at people skeptical of the threat of climate change.
1. Actress Emma Thompson joined a climate protest march on her home turf of London. Thompson said, “I haven’t taken a plastic bag from a supermarket for about ten years.” She also said serious decisions need to be made for climate change and that might mean “we might not be able to have our own cars.”
2. Actor turned former California governor, Arnold Schwarzenegger, ranted about terminating climate change. In a Dec. 7, Facebook post he said he does not “give a **** if we agree about climate change,” then went on to argue for renewable energy even if the science is wrong.
“I don’t give a damn if you believe in climate change. I couldn’t care less if you’re concerned about temperatures rising or melting glaciers. It doesn’t matter to me which of us is right about the science,” he wrote.
The governator sided with lefty environmentalists at the COP21 summit, saying climate change is “the most important issue” and claiming “7 million people die a year because of pollution,” according to reports from The Hill and The Guardian.
3. During the conference, actor Peter Sarsgaard was the judge of a mock trial put on by climate activists Bill McKibben and author Naomi Klein. The trial was called “The People v. ExxonMobil: A Public Trial for the Greatest Climate Crime of the Century.” 
Yes, a liberal celebrity was appointed, along with two other “judges” to decide the fate of the world’s biggest oil company—and Exxon didn’t even get an invite to its own fake trial. Kidding aside, the activists running that trial would much rather see the real thing.
4. Radiohead’s lead singer, Thom Yorke, participated in the London climate march before the Paris conference began. Standing atop a Greenpeace float decorated with polar bears, Yorke DJ’d for the marching protesters. He also joined many others in "the creative community” by signing a petition calling on the officials meeting in Paris to commit to “climate action” to limit warming to less than 2 degrees with a “legally robust and accountable global governance framework.”
5. Actor and film director Robert Redford, who is also a trustee of the liberal environmentalist group Natural Resources Defense Council, called on mayors to reduce emissions in their cities, AP reported. “I think we’re running out of time because the planet is running out of resources,” Redford claimed.
He accused congressmen skeptical of the threat of global warming of essentially being bought and paid for. Time reported that Redford said, “Those people in Congress who are climate deniers, I think their time has run out.” Naturally, he used the offensive “deniers” term popularized by the left and media in spite of its Holocaust connotation.
“The people that are involved with oil, gas, coal, they’ve been running the show for a long, long, long time. And their time has run out,” Redford said.
