"Antarctica: Mystery Continent Holds Key To Mankind's Future"

"DECEPTION ISLAND, Antarctica — Earth's past, present and future come together here on the northern peninsula of Antarctica, the wildest, most desolate and mysterious of its continents.

Clues to answering humanity's most basic questions are locked in this continental freezer the size of the United States and half of Canada: Where did we come from? Are we alone in the universe? What's the fate of our warming planet?

The first explorers set foot in Antarctica 194 years ago hunting 19th century riches of whale and seal oil and fur, turning tides red with blood. Since then, the fist-shaped continent has proven a treasure chest for scientists trying to determine everything from the creation of the cosmos to how high seas will rise with global warming."
