"By the end of this century, if emissions keep rising, the average temperature on Earth could go up another 4 to 8 degrees," he said on Monday’s episode. "What I'm saying is the planet's on [expletive] fire."
To demonstrate, Nye grabbed a blowtorch and set fire to a globe.
"There are a lot of things we could do to put it out," he continued, gesturing toward a fire extinguisher, blanket and sand bucket. "Are any of them free? No, of course not! Nothing's free, you idiots. Grow the [expletive] up!"
Nye added: "You're not children anymore. I didn't mind explaining photosynthesis to you when you were 12, but you're adults now, and this is an actual crisis."
Nye's appearance came during a segment on the Green New Deal and carbon pricing.
"Many thanks to the fantastic @BillNye for explaining Carbon Pricing to us with an entirely appropriate amount of profanity," host John Oliver tweeted after the show.
