Temperature vs. time

Here is the amplitude spectra for overlapping 12 year long, weekly data series from the Mauna Loa Observatory transformed to time series of 52 week increments of the CO2 concentration. They illustrate changes in the spectra with the progression of time. This is attributed to the ever changing configuration of the Solar system.
