Bill Nye was the hero of my generation.

Science class that started with a teacher’s lecture was a toss-up. Maybe good, maybe bad. But a science class that started with Bill Nye the Science Guy’s theme song was a guaranteed winner.

That’s why it is totally awesome to see Bill Nye back in this short video, explaining science in ways kids can understand. He uses emojis, of all things, to break down the concept of global warming.

This is a must see.

BILL BILL BILL BILL.
