Since 1976, the Dead Sea's level has dropped more than 100 feet, leaving its coastline pockmarked with thousands of sinkholes. NOVA follows the unprecedented endeavor to connect the Red Sea to the Dead Sea by way of a massive desalination plant - perhaps the world's largest water chemistry experiment - as scientists race to save the Dead Sea and bring water to one of the driest regions on Earth.

The Great Lakes region provided geologists with much of the evidence for the frequent ice ages that visited North America. But the lakes may be a rather transient feature of the continent dependent upon the recurring ice ages to maintain their existence.

For many people, the Swiss Alps are a natural paradise. But in fact this paradise in man-made. Alpine meadows exist only because farmers have been driving their livestock up into the mountains for centuries. Now the ancient traditions are disappearing and the forest is spreading more and more.

NOVA follows a team of volcano sleuths as they embark on a worldwide hunt for an elusive volcanic mega-eruption that plunged the medieval earth into a deep freeze. The mystery begins when archaeologists find a hastily dug mass grave of 4,000 men, women, and children in London. At first they assume it's a plague pit from the Black Death, but when they date the bones, they're a century too early. So what killed off these families? The chronicles of that time describe a run of wild weather that devastated crops and spread famine across Europe. NOVA's expert team looks for the signature of a volcanic eruption big enough to have blasted a huge cloud of ash and sulfuric acid into the atmosphere, which chilled the entire planet. From Greenland to Antarctica, the team finds telltale "fingerprints" in ice and soil layers until, finally, they narrow down the culprit to a smoldering crater on a remote Indonesian island. Nearly 750 years ago, this volcano's colossal explosion shot a million tons of rock and ash into the atmosphere. Across the globe, it turned summer into winter. What would happen if another such cataclysm struck again today?
