July 16 - Watch Extreme Science with Philippe Cousteau on CNN International

In the one-hour documentary program Extreme Science, Philippe Cousteau will take viewers to one of the coldest places on earth, the Arctic, to explore the significance of the science studied in extreme conditions. To study the effects of global warming at the Catlin Ice Base, scientists test the salinity levels of the water and its acidification. They also have to maintain a plane runway, prepare for the event of a polar bear attack, and generally operate in freezing temperatures that regularly dip down to -40 degrees.

Philippe blogged about his Arctic adventures while shooting this documentary. Get a sneak peak by reading those entries here.
