claim: 'Mauna Loa has been producing a readout which supports Manning's predetermined goal by showing steady growth in atmospheric CO2 concentrations since 1959.
evidence: Since 1958, initially under the direction of Charles Keeling, followed by his son Ralph and later Elmer Robinson, Mauna Loa Observatory ( MLO ) has been monitoring and collecting data relating to atmospheric change, and is known especially for the continuous monitoring of atmospheric carbon dioxide ( CO2 ), which is sometimes referred to as the Keeling Curve.
