CO2 is a minor component of the so called "greenhouse gasses". Further, there is evidence to suggest that it is a result of global temperature increases, rather than the cause.
Would you possibly think that maybe just maybe... humans weren't around for all the other "warming" events? Meaning, this isn't the same kind of event?
Prehistorically, the CO2 came after an initial factor warmed this rock, and then was a magnifying factor for said "warming". Put quite simply... if it's not a natural event, then the natural order of things would not bear out to be true. Prior warming events followed this order due to natural events that started the cycle. This is why CO2 historically lags the warming by a statistically small percentage. If we skip the first step, and go right to the second....duh... CO2 will then lead the exponential curve. Simple deduction, sir.
This is exactly what is born out in coring records. An event warmed the planet, natural shift in orbit or solar radiation, which caused a release of CO2; the CO2 magnified the warming, until it was reduced by natural CO2 sinks, and then the temperatures followed. No one has ever said CO2 is a powerful global warming agent. It magnifies the energy that the planet receives. I've repeatedly said, we need to worry about CH4 (methane) stored in hydrate form. That's the really bad egg on the horizon, if the ocean continues to warm.
We are also in a solar minimum, at the start of solar cycle 24. (apparently, the sun can't make up its' mind, as evidenced by a Cycle 23 spot that formed a few days ago for about 6 hours.) Solar output is currently at about the lowest it has been measured. And, yet, this past summer the arctic still was almost ice free. Antarctic ice shelves are collapsing..... at a solar MINIMUM. It doesn't take rocket science or a PhD to figure out things are screwy.
