Harrison Ford urged voters on Thursday to stop electing those who reject scientific evidence and statistics.

While delivering remarks at the Global Climate Action Summit in San Francisco, the “Star Wars” and “Indiana Jones” star called for voters to “stop giving power to people who don’t believe in science, or worse than that, pretend they don’t believe in science for their own self-interest.”

Ford said those who he was referring to “know who they are” and that “we know who they are.”

The 76-year-old actor also warned attendees that the “future of humanity was at stake” due to climate change.

“We are all — rich or poor, powerful or powerless — we will all suffer the effects of climate and ecosystem destruction,” Ford said. “And we are facing what is quickly becoming the greatest moral crisis of our time. Those least responsible will bear the greatest costs.”

He also called on attendees to “shut off [their] phones, roll up [their] sleeves and kick this monster’s ass.”

Ford went on to say that the “greatest moral crisis of our time" was that “those least responsible will bear the greatest costs,” while adding: “We are shit out of time.”

Ford, an outspoken and longtime advocate for environmental causes, took a similar swipe at leaders in Washington last November during a speech to the environmental group Conservation International in Culver City, Calif.

"We face an unprecedented moment in this country. Today’s greatest threat is not climate change, not pollution, not flood or fire," Ford said at the time. "It’s that we’ve got people in charge of important shit who don’t believe in science."

He also argued in the speech that unless climate change is addressed quickly, "nothing else will matter."
