P-S! Hey, Smarty Pants! Trusty Nader here in a helicopter hovering over someplace very, very cold.

See if you can guess where I am.

But first, I'll let Chet Nickerson, whose newschopper we're borrowing, give you some hints.

Ready? Take it away, Chet.

This is Chet Nickerson reporting live with some hints as to the trusty narrator's whereabouts.

First, in the distance, I see big chunks of ice sticking out of the water. Next, I spy a

walrus sleeping on some ice below us.

And thirdly, through my binoculars, I can make out a hungry polar bear chasing a seal.

So, where am I, Smarty Pants?

If you said the polarize cap in the Arctic Sea, you're right. Also with us is our

pilot slash climate scientist Jess. Hello, Smarty Pants. Jess is about to set our whirly bird down

on a smooth sheet of ice. From there, she'll be taking some ice core samples back to a lab in northeast Alaska,

so she and her fellow scientists can conduct tests on them.

Roger, setting down at 42.5 Marker 22.

That's fancy helicopter talk for landing.

Run here that.

Smarty pants, besides the temperature, you want to know what's really cool about this place? It's nearly midnight, and I'm wearing sunglasses because the sun is so bright. Yep. In fact, it won't get dark the entire summer. But why is that?

It has to do with the Earth's position during the summer months. The planet is tilted towards the sun, and as it spins around counterclockwise, the top and bottom remain in place, so both the north and south poles stay in constant sunlight.

That might make it hard to sleep.

Yep, or to even know when to sleep.

So, what do our listeners need to know about the polar ice caps?

Well, for starters, do you know what the term polar ice caps means?
