Understanding Atmospheric Oxygen: The Other Half of the Global Carbon Dioxide Story
First Aired: 01/09/2008
Increases in global carbon dioxide should be mirrored by decreases in atmospheric oxygen. Join Ralph Keeling to learn how his precise measurements have shown that the concentration of oxygen in the atmosphere is in fact decreasing slowly from year to year and discover how these data are allowing scientists to place constraints on the global carbon cycle.
