Harrison Ford delivered a blistering takedown of Donald Trump while speaking to The Guardian this week ahead of receiving a conservation leadership award at Chicago’s Field Museum. The “Star Wars” and “Indiana Jones” icon ripped the president for his ignorance towards climate change and his dismantling of the government’s climate policies.

“[Trump] doesn’t have any policies, he has whims. It scares the shit out of me,” Ford told the publication. “The ignorance, the hubris, the lies, the perfidy. [Trump] knows better, but he’s an instrument of the status quo and he’s making money, hand over fist, while the world goes to hell in a hand basket. It’s unbelievable. I don’t know of a greater criminal in history.”

Just last month, Trump told the United Nations that climate change is “the greatest con job ever perpetrated on the world,” adding: “If you don’t get away from this green scam, your country is going to fail. You need strong borders and traditional energy sources if you are going to be great again.”

As recounted by The Guardian: “Trump has set about dismantling climate and clean air protections, halted clean energy projects, urged oil and gas companies to ‘drill, baby, drill’ for the fossil fuels that are overheating the planet, fired hundreds of scientists while deleting their work, and even banned mentions of ‘climate change’ and ’emissions’ within government.”

“I knew it was coming, I have been preaching this stuff for 30 years,” Ford said about climate change and the increase in climate-related disasters. “Everything we’ve said about climate change has come true. Why is that not sufficient that it alarms people that they change behaviors? Because of the entrenched status quo.”

“He’s losing ground because everything he says is a lie,” Ford added about Trump before pivoting to a message of optimism. “I’m confident we can mitigate against [climate change], that we can buy time to change behaviors, to create new technologies, to concentrate more fully on implementation of those policies. But we have to develop the political will and intellectual sophistication to realize that we human beings are capable of change. We are incredibly adaptive, we are incredibly inventive. If we concentrate on a problem, we can fix it most times.”
