And most importantly, what does the future hold for the glaciers of Greenland? In this video, glaciologist Mark Fahnestock discusses glacier dynamics and what he hopes to learn through his studies.

An interview with Mel Zucker, Professor of Geology, Skyline College, San Bruno, California.

In the early 1900s, German meteorologist Alfred Wegener suggested that the earth's continents were once a single landmass that had somehow split into pieces, drifting their separate ways. Geologists the world over called his idea preposterous. Decades later, their ridicule shifted to admiration as new tools developed by the military to map the ocean floors revealed the engine that drives the continents' movement. Geology professor Mel Zucker tells the story of this brilliant earth scientist and how, long after his death, science finally caught up with Wegener's crazy idea.
