Head of NOAA: Earth Has "Planetary Fever" - Dr. Kathryn Sullivan

Dr. Kathryn Sullivan a former space-walking astronaut with a background in geology and a present studying oceans has a lifetime's worth of experiences that leave her uniquely qualified to lead the National Oceanic and Atmospheric Administration. Dr. Sullivan points to acidification as a threat to oceans that could damage the global food chain's foundations, which prevent oysters, coral and many other organisms from forming their protective calcium shells. Sullivan compares the warming climate to a planetary fever that needs treatment, but agrees that motivating humans to act for the greater global good can be difficult.
