Sought by explorers for centuries as a possible trade route, until 2009, the Arctic pack ice prevented regular marine shipping throughout most of the year, but climate change has reduced the pack ice, and this Arctic shrinkage has made the waterways more navigable.

'The Polar Explorer' explores one of the first scientific expeditions through the Passage, focusing on the effects of climate change in this Arctic region.

Over the past 30 years, the Arctic has warmed at roughly twice the rate as the entire globe, a phenomenon known as Arctic amplification. Most scientists agree that this rapid warming is a signal of human-caused climate change.

If you would like to win a copy of this intriguing new DVD, just answer this easy question: Climate change may result from such factors as, but definitely not limited to, changes in solar activity and long-period changes in the earth's orbital elements (eccentricity, obliquity of the ecliptic, and precession of _________).

But what is that missing word?!
