Popular scientist Bill Nye is known for explaining all sorts of things to us, but today he’s talking climate change using emojis.

In a 90-second video complete with emoji demonstration, Bill Nye not only explains why the climate is changing, he also gives the world some instructions for the future:

“Let’s use electricity! We could generate it renewably from wind and solar, and then the key is that we have to move it around the world through cool new transmission lines that someone is going to invent and develop and fund and distribute and then if we had a better battery, a better system, a better scheme of electrical energy storage, we could — dare I say it? — change the world!”
