Sun, ocean, climate and atmospheric 14CO2 : an evaluation of causal and spectral relationships
Solar (heliomagnetic), geomagnetic and oceanic forcing all play a role in atmospheric 14 CO 2 change. Here we assign the variance associated with certain periodicities in a single year (0-450 cal. BP) and a Holocene bidecadal (0-11400 cal. BP) 14 CO 2 record to specific forcing factors. In the singl...

Solar (heliomagnetic), geomagnetic and oceanic forcing all play a role in atmospheric 14 CO 2 change. Here we assign the variance associated with certain periodicities in a single year (0-450 cal.

In the single-year time series the variance in the 2-6-year periodicity range is attributable to El Niño-Southern Oscillation (ENSO) ocean perturbations. A 10-11-year component is partially tied to solar modulation of the cosmic ray flux, and multidecadal variability may relate to either solar modulation or instability of the North Atlantic thermohaline circulation. For the early Holocene bidecadal 14 C record we derive a 512-year atmospheric 14 C periodicity which relates to instabilities in North Atlantic thermohaline circulation. North Atlantic deep water formation increased near the start, instead of the termination, of the Younger Dryas interval.
