If you were a kid in the 90’s through the early 00’s, one of your fondest memories from grade school is probably those days when your teacher would wheel in the giant TV that was strapped to a clunky black metal cart and pop a Billy Nye the Science Guy video into the VCR. Bill Nye was always the absolute MASTER of explaining literally any and every scientific concept in ways that were easy to understand and absorb, and also incredibly entertaining — for kids AND adults.

Come on, admit it, whenever his name pops up you definitely still chant “BILL, BILL, BILL, BILL” in your head.

He’s educated and entertained millions of kids, but guess what? We’re not kids anymore, and he’s got a much more adult message to share with us.

In an episode of Last Week Tonight with John Oliver, Bill Nye unveiled a new experiment to demonstrate the reality of climate change and the cost of saving the planet, and HE. GOT. REAL.

Although he’s had a show geared towards an adult audience since 2017, Bill Nye Saves The World, this is definitely the most blunt and brash we’ve seen our beloved bowtie-clad scientist, and for good reason — HE’S RIGHT.

Since the time this article was originally written back in May 2019, things, uh, have not gotten better, folks! A heatwave just melted 20% of the snow covering one of Antarctica’s islands in just nine days. The recent wildfires in Australia burned across 12.35 million acres of land. And the current administration in the USA is doing anything and everything in order to roll back environmental protections — like, seriously some supervillain-type shit, guys! So when you’re thinking about who to vote for in the upcoming election, think to yourself:

What would Bill Nye do?!
