Fossil Coral Reveals Climate Trends

By examining a set of fossil corals that are as much as 7,000 years old, scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation, a Pacific Ocean climate cycle that affects climate worldwide. This video shows how the fossil coral samples are collected and analyzed. (Credit: Inertia Films/Georgia Tech)
