Arnold Schwarzenegger says he wishes he could travel back in time like the cyborg he played in “The Terminator” so he could stop fossil fuels from being used.

“If we would’ve never started in that direction and used other technology, we’d be much better off,” the actor and former California governor said Monday at the start of a UN climate conference in Poland.

“The biggest evil is fossil fuels: it’s coal, it’s gasoline, it’s the natural gas,” he told conference delegates.

Schwarzenegger also insisted that the United States was “still in” an international accord to curb global warming despite US President Donald Trump’s decision to walk away from the agreement.
