[CO2 and temp corelation in the glacial record]

A lag of 800-1,000 years might mean that recent rise in CO2 is a
response to Medieval Warm Period.

Don't you think the isotope signature of the CO2 increase makes this even
less than unlikely?

No. The year-to-year variation in estimated anthropogenic CO2 emissions
doesn't seem to correlate well with any variations in the increase in
atmospheric concentrations. It's true enough that they're both
increasing. But the hypothetical question of what would CO2
concentrations be today even if we had never burned coal-oil-gas is not
so straightforward to answer. I'm curious at the folks who point to the
ice core evidence of CO2-temperature as a pillar of the science yet they
don't seem to take the implications of the lag (CO2 rise always lags
temperature proxy rise in the ice cores) at all seriously.

That's because the mechanisms of CO2 emissions are different. After the
Ice Ages, the melting ice probably RESULTED in the CO2 level increasing.
In the present situation, there are no large ice sheets and the CO2
increase is said to be the CAUSE of warming. Thus, the timing is
different. Why do you find it so difficult to understand that?

I do understand the type of theory you present. Do you think ice didn't
melt during MWP?

Splendid mis-direction there Steve. How about admitting that as the
Earth warms from which I take it that you do agree that after the
Ice Ages, the melting ice probably RESULTED in the CO2 level increasing.
In the present situation, there are no large ice sheets and the CO2
increase is said to be the CAUSE of warming. Thus, the timing is
different.

Glad to see you agree.

PS: Coby and Eric this is one of Steve's favorite tactics, dragging a
red herring across the path to hide the trail. Don't fall for it.
