Wherever you are right now, chances are you're relatively comfortable. Maybe you're inside an air-conditioned room (or a heated one if it's still cold outside).
You're probably surrounded by four walls that protect you from the elements. And you're holding a supercomputer that can access the Internet. You've got it made in the shade, friend.
But before you get too comfortable, I'd like to show you some images that prove that as long as you're living on this planet, you probably shouldn't be completely relaxed because Mother Nature has some serious tricks up her sleeve.
