In this section are presented two Fourier deconvolution of (1) the global temperature anomaly of atmosphere (UAH, University of Alabama in Huntsville) and of (2) surface oceanic waters (NOAA-SST). In the two following figures these two Fourier analyses are compared with the 12 month change of atmospheric CO2 (the difference between Mauna Loa values of the same month in two different years).

It is clearly seen the time lag of about 9 months of CO2 change in respect to atmospheric data and of about 16 months in respect to oceann temperature data.

So the sequence of the events is seawater heats --> air heats up --> CO2 increases
