Glaciologists measure outflow of the Kangerdlugssuaq Glacier

Dear Readers, I've seen a lot of these videos, but this one is particularly interesting and well worth viewing.

On the Kangerdlugssuaq Glacier -- one of Greenland's largest ice fields -- scientists measure the movement of the ice sheet as it transports frozen water to the ocean. They discover that the speed of the glacier's march to the sea has tripled in just ten years. Alarm bells sound because at the current melt rate, within a few decades rising seas will have a profound effect on the low-lying countries of the world.

Once considered an inexhaustible source of food, the oceans are now in danger of being significantly depleted. Matt Damon hosts "The State of the Planet's Oceans" as award-winning filmmakers Hal and Marilyn Weiner investigate the health and sustainability of the world's oceans and the issues affecting marine preserves, fisheries, and coastal ecosystems worldwide.
