The lagged responses of the Earth’s climate system, as part of cosmic-solar-terrestrial processes, are empirically modeled with a consequent estimation of a lag of ~1600-yr for the recently detected ~9500-yr scale solar recurrent patterns. Several examples of this kind of lag, both in forcing (Volcanoes & CO2
), tropical climate and ocean processes throughout the Holocene, were analyzed. The results suggest that the recent CO2
increase can be considered as a lagged response to solar activity.
