Most recent of these are the lawsuits being filed against major oil companies, with Hollywood action star and former California Governor Arnold Schwarzenegger piling on with his first-degree murder charges.
Schwarzenegger said that like the tobacco industry's paying hundreds of billions of dollars after being found responsible for lying about the health effects of smoking, the oil industry has lied about what it has known about the effects of fossil fuel pollution.
"This is no different from the smoking issue".
Schwarzenegger said during an interview with Politico's "Off Message" podcast that he is still working on the timing for his push, but he is now speaking with private law firms.
On the podcast, Schwarzenegger made a comparison between oil and tobacco, a product that kills 480,000 people per year in the USA, according to the CDC.

South Africa can not fight the move towards renewable power, energy expert Chris Yelland said on Tuesday. Below are some of the reactions expressed on Twitter.
Like many other environmental advocates, Schwarzenegger sees a direct parallel between what happened with the tobacco industry and what is now happening with the oil industry.
Reuters quoted San Francisco officials as saying that the five oil companies "knowingly and recklessly created an ongoing public nuisance that is causing harm now and in the future risks catastrophic harm to human life and property".
"We're going to go after them, and we're going to be in there like an Alabama tick", he continued at the SXSW festival.
Schwarzenegger also took several shots at President Donald Trump, including a joke about the plot of his next Terminator movie, which begins production in Europe in June. Schwarzenegger did not offer any comparable death statistics related to oil, but he proposed that every gas station, auto and fossil fuel product should have a warning label on it - just as with tobacco. "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. He hopes that this will raise awareness about cleaner cars and alternative fuels. How the American populace -which, despite being the world's second-highest greenhouse gas emitter, has not fully accepted climate science - reacts to a movement directly exposing the global footprint of the oil industry will be a useful indicator of how willing the country is to combat climate change.
