Harald Yndestad: Lunar Forced Mauna Loa and Atlantic Variability

SCC Volume 2.3.

The source of atmospheric CO2 variations is poorly understood. At Mauna Loa Hawaii, atmospheric CO2 has been recorded from 1959. This is a short period for a reliable variability signature identification. From the 19th century, atmospheric CO2 has been recorded in several short periods over the Atlantic Ocean and Europe.

A number of these data series are compiled into a single atmospheric Atlantic CO2 data series from 1820 to 1960. Altogether, this time series covers atmospheric CO2 records over a total period of 200 years. In this investigation, a wavelet spectrum analysis identifies the signature of Mauna Loa atmospheric CO2 growth from 1960 to 2020 and Atlantic atmospheric CO2 for the period 1870 to 1960. The result reveals that the Atlantic CO2 variability from 1870-1960 coincides with Mauna Loa CO2 growth variability, global sea surface temperature variability and lunar nodal tide variability. The Atlantic CO2 signature and global sea surface temperature signature and the have a phase difference of p/2 (rad), which reveals a sea temperature driven atmospheric CO2 variation. The CO2 variability signature coincides with the global sea temperature signature and the lunar nodal signature spectrum. The identified lunar nodal tide spectrum reveals a chain of events from lunar nodal tide variations to global sea surface temperature variations and atmospheric CO2 variations. A lunar nodal tide spectrum in atmospheric CO2 growth reveals that CO2 is not controllable.
