    April monthly average exceeds 410 parts per million for the first time
    in recorded history

    The average concentration of carbon dioxide in the atmosphere was 410.31
    parts per million (ppm) for the month of April, according to the Keeling
    Curve measurement series made at the Mauna Loa Observatory in Hawaii.

    This marks the first time in the history of the Mauna Loa record that a
    monthly average has exceeded 410 parts per million. This also represents
    a 30-percent increase in carbon dioxide concentration in the global
    atmosphere since the Keeling Curve began in 1958. In March, Scripps
    Institution of Oceanography at the University of California San Diego
    observed the 60th anniversary of the data series, the first measurements
    of which were 315 ppm.
