Twenty eight years ago, this is what the polar ice cap the North Polar ice cap looked like at the end of the summer, at the fall equinox.

Auroras Underfoot.

This is a bowhead whale.

We fly right over them.

Auroras are caused by solar activity.

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color.

Especially when you deal with polar coordinates.

The vanishing Arctic sea ice also affects the atmosphere.

I'll bet 3,000 that she'll send him to Sejong Antarctic Research Center. lt BR gt

We were attacked by a polar bear on day two.

A polar bear can swim up to 500 kilometers.

It is not disorienting to see auroras underfoot, he says.

Indeed, more auroras are in the offing.

And the water at the North Pole is minus 1.7.

Its southern counterpart, the aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone.

Some companies even seem to celebrate the melting of the polar ice cap, because it will reduce the cost of extracting the oil that lies beneath the Arctic Ocean.

Early evidence for a geomagnetic connection comes from the statistics of auroral observations.

All these islands lie in the cold seas below the Antarctic convergence.

The collection of these interactions is what creates the northern and southern lights.

From this book anyone can learn about the aurora borealis or the Eskimos

A polar bear wouldn't hesitate to attack a huge walrus if it were hungry.

The protons and electrons creating the northern lights depart from the Sun's corona.

These are actually polar dipole bonds with the different sodium or chloride ions.

The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean.

In 1948, the underwater Lomonosov Ridge in the Arctic Ocean was named in his honor.

And you might want to watch my polar coordinate videos, because this essentially touches on that.

We can actually fly into the auroras, says astronaut

Sometimes you feel like you can reach out and touch them.

Some are a joint effort between the scientific communities of two or more States, such as the Arctic Mid Ocean Ridge Expedition in 2001, conducted by scientists from the United States and Germany.34

Projections are that we could lose polar bears they could become extinct in the next 50 to 100 years.

Today, a far greater Arctic tragedy is unfolding the Arctic sea ice cap is melting.

For instance, as the Arctic ice cap melts, less sunlight is reflected.

The first, the Polar Atmospheric Chemistry Programme, is presently active only in the Arctic.

If we were to think of this in polar coordinates, this is t at any given time.

And from out of stage left comes this wild, male polar bear, with a predatory gaze.

And this polar bear stands over the husky, no claws extended, no fangs taking a look.

Projections are that we could lose polar bears, they could become extinct in the next 50 to 100 years.

Longtime sky watchers say it is the greatest show on Earth.

82 to 86 of people with bipolar disorder, have suffered from some form of childhood trauma.

What is that thing reduced to lowest terms?
