Charles D. Keeling, in his lab at Scripps Institution of Oceanography. Keeling was a scientist who recorded atmospheric carbon dioxide at the Mauna Loa Observatory, thus showing an anthropogenic contribution leading to the greenhouse effect. The Keeling Curve measures the progressive buildup of carbon dioxide, a greenhouse gas, in the atmosphere. As a result Keeling was presented with a "special achievement award" from the 45th Vice President of the U.S. Albert Arnold Gore. In 2002, George W.
