I can't believe how the entire premise of global warming caused by CO2 increase has been so easily sold to the public. One of the teams involved with the ice core CO2/temperature data was led by French expert Dr. Nicholas Caillon. Here is a link to their research paper;
Timing of Atmospheric CO2 and Antarctic Temperature Changes Across Termination III
In it are tidbits like this;
"The analysis of air bubbles from ice cores has yielded a precise record of atmospheric greenhouse gas concentrations, but the timing of changes in these gases with respect to temperature is not accurately known because of uncertainty in the gas age-ice age difference. We have measured the isotopic composition of argon in air bubbles in the Vostok core during Termination III (-240,000 years before the present). This record most likely reflects the temperature and accumulation change, although the mechanism remains unclear. The sequence of events during Termination III suggests that the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years and preceded the Northern Hemisphere deglaciation."
"This confirms that CO2 is not the forcing that initially drives the climatic system during a deglaciation. Rather, deglaciation is probably initiated by some insolation forcing (1, 31, 32), which influences first the temperature change in Antarctica (and possibly in part of the Southern Hemisphere) and then the CO2. This sequence of events is still in full agreement with the idea that CO2 plays, through its greenhouse effect, a key role in amplifying the initial orbital forcing. First, the 800-year time lag is short in comparison with the total duration of the temperature and CO2 increases (~5000 years). Second, the CO2 increase clearly precedes the Northern Hemisphere deglaciation."
The Caillon team paper goes on to mention a delay of 800 years "seems to be a reasonable time period to transition from an initial Antartic temperature increase into a CO2 atmospheric increase though oceanic processes". The mechanism might be "a change in vertical ocean mixing", consistent with "a process that involves the deep ocean as its mixing time is close to the observed 800 year lag". They offer cryptic comments like "sequence of events is still in full agreement with the idea that CO2 plays, through its greenhouse effect, a key role in amplifying the initial orbital forcing. "
Ok an "idea", what's that? The absolute objective truth? "The radiative forcing due to CO2 may serve as an amplifier of initial orbital forcing, "
"May"?? What's that, the absolute objective truth?
"Initial orbital forcing"?? What's that? Temperature increasing first?
One more thing the Caillon paper states is that the the 800 year lag cannot rule out any of these mechanisms - "vertical ocean mixing, sea-ice cover changes, or a biological mechanism such as atmospheric dust flux or ocean productivity" - as having sole control of CO2 outgassing.
"Sole control", how about that?
