How Carbon Dioxide Kills Ocean Life

June 23, 2014 - Warming and acidification from carbon dioxide in our atmosphere are having long-term effects on life in our oceans. In this video from Earth Vision Trust, marine ecologist and geologist Joanie Kleypas, of the National Center for Atmospheric Research, explains how carbon dioxide changes the pH level of the ocean and how that leads to coral die-off. She also helps us understand how humans can help restore damaged coral reefs. 

Earth Vision Trust, a nonprofit founded by National Geographic photographer and grantee James Balog, seeks to educate and inspire the public through innovative visual exploration of the changing environment.
