Actress Sigourney Weaver offered a dark picture of the world’s future during her speech at the Democratic National Convention Wednesday night. In her remarks, Weaver warned Americans that if we don’t act to combat climate change, doom is imminent.

The DNC then aired a video featuring Weaver as the narrator.

“It’s happening now,” Weaver says in the video. “The droughts, the record heat waves,” etc.

“This is not something we’ve seen before,” she claims. “Our children are at risk.”

Using remarks from everyone from Pres. George H.W. Bush to Pope Francis, the short film insists the world is at risk thanks to global warming. The video also uses sound bites from families whose homes have been destroyed by natural disasters to prove Weaver's point.

In one particular scene, a man who claims to be a conservative Republican expresses his own concerns about climate change.

“A thermometer is not Republican,” he says. “A thermometer is not Democrat.”

The film also highlights Donald Trump’s climate change denial and contrasts it with Hillary Clinton’s promise to tackle it.

“Together we can do this,” she says. “For our future, for our children.”

The video was inundated with footage of homes burning in wildfires and cars drowning in hurricanes.

This, after liberal pundits claimed Trump’s speech at the RNC last week was too dark.
