Arnold Schwarzenegger says he is going after Big Oil and climate change. The actor and former governor of California said in a Politico-sponsored podcast ... that he is in talks with law firms about possibly suing global oil companies "for knowingly killing people all over the world." "The oil companies knew from 1959 on, they did their own study that there would be global warming happening because of fossil fuels, and on top of it that it would be risky for people's lives, that it would kill," Schwarzenegger said. "I don't think there's any difference: If you walk into a room and you know you're going to kill someone, it's first degree murder; I think it's the same thing with the oil companies," he said. In the podcast, Schwarzenegger compares the issue to the tobacco industry. "The tobacco industry knew for years and years and years and decades, that smoking would kill people ... and were hiding that fact from the people and denied it," Schwarzenegger said. "Then eventually they were taken to court and had to pay hundreds of millions of dollars because of that." He argues that every gas station, car and product with fossil fuels should have a warning label on it. He hopes that this will raise awareness about cleaner cars and alternative fuels. "We're going to go after them. Because to me it's absolutely irresponsible to know that your product is killing people and not have a warning label on it, like tobacco," he said.
