@MontereyJack,
Brace yourself, it's time someone rattled your associated bandwagon.
I don't deny that the climate is changing. This bandwagon you've jumped on goes alone on correlations from insufficient evidence (ground temperature data set, but last time I checked,temperature scales only goes back as 18th century) tied in with statistical computer models and theoretical what if's, which are all tied with further correlations. Any day, I'll take data (especially geophysical data that looks at very long (glacial-interglacial) timescales that extends well past 18th century) over computer modeled theories. There are ice core studies with data that suggests there are lag of carbond dioxide in ice cores behind the temperature rise. Then there have been data coming from the arctic of increase in output of methane gas.
From the data available, CO2 should be thought of as a feedback. CO2 does not initiate the warmings, but acts as an amplifier once they are underway.
The probably sequence of events started with some unknown (as of yet) process that caused the surrounding ocean around Antartica to warm. This unknown process also causes CO2 to start rising, about 800 years later. Then CO2 further warms the whole planet, because of its heat-trapping properties. This leads to even further CO2 release. You must understand that if humans are absent without any interventions from us, CO2 does rise and fall over time, due to exchanges of carbon among the biosphere, atmosphere, and ocean and, on the very longest timescales, the lithosphere (i.e. rocks, oil reservoirs, coal, carbonate rocks). The rates of those exchanges are now being completely overwhelmed by the rate at which we are extracting carbon from the latter set of reservoirs and converting it to atmospheric CO2.
But I'm open to data. Show me unbiased, sufficient data that directly shows that global warming is anthropogenic in origin, and I'll jump on your rickety bandwagon in a heart beat.
