Bill Nye has spent years boiling complex science topics down for kids across the world. During a recent episode of HBO's Last Week Tonight With John Oliver, he kept it 100 when discussing climate change.

“By the end of this century, if emissions keep rising, the average temperature on Earth could go up another four to eight degrees," Nye said

"What I’m saying is the planet’s on f*ck*ng fire.”

He playfully demonstrated our predicament when he took a blowtorch to a globe as an example of what will happen if we don't take concrete steps as a planet to reduce our carbon emissions.

“There are a lot of things we could do to put it out, are any of them free? No of course not, nothing’s free you idiots, grow the f*** up," he joked as he stood next to the burning globe.

"You’re not children any more. I didn’t mind explaining photosynthesis to you when you were 12 but you’re adults now and this is an actual crisis. Got it? Safety glasses off motherf*c*er.”

Oliver spent the episode digging deep into the Green New Deal, a plan by liberal lawmakers to address climate change. New York Congresswoman Alexandria Ocasio-Cortez has been one of its biggest backers. She is largely credited with bringing the conversation about the plan and climate change to a larger audience.

“We’re going to need a lot of different policies working in tandem and we have to take action right now. But you don’t have to just take that from me," Oliver said near the end of his show.

"Instead, I’m happy to say that Bill Nye has actually agreed to help drive the urgency home at this point by actually doing one of his enjoyable, light-hearted demonstrations. So Bill, please, please, do you have a fun experiment for us?”
