  1. Superimposedd on the Keeling Curve is an annual cycle that has an amplitude of about 7 ppm – with a peak in May. Historically it falls from teh May peak and will not ‘recover’ to that value until about March the following year.
    I ‘forecast’ we won’t see 400 ppm in 2013. Maybe next Spring, after another hard, cold winter.
    Even so, the CO2 levels have climbed over 25% since the late 50’s, and the temperature increase has simply FAILED to keep pace with it.
