A Brief History of CO2 Measurements

JPL Historian Erik Conway provides an overview of the sequence of events that lead to the link between human activity, carbon dioxide, and global warming. Conway also examines how the spaceborne instrument, the Atmospheric Infrared Sounder, has become part of the story. Charles Keeling points out the steady rise in carbon dioxide that came to be known as the Keeling Curve.
