CO2 released from the ocean ? and what in the ocean releases CO2 ?
Bingo! Yes, the ocean is a tremendous HUGE "sink" (kind of like a heat sink but for gases and liquids instead of heat)...a BUFFER if you will for all atmospheric gases. When the weather is cold, CO2 gets absorbed by the oceans in greater concentrations. When the weather is warm, the CO2 is released.
Indeed, we have seen a warming cycle in the past 150 years, prior to that we had a cooling cycle called the Little Ice Age (LIA), and prior to that, we had a warm cycle called the Medieval Warm Period, another cool period before that, and a Roman Warm Period before that and so on.
In all cases the CO2 concentration went up. Granted, it is a higher degree of concentration now than then because of industrialization (and probably as much so because of deforestation)...However, there is no conclusive evidence that the CO2 causes warming. Real scientific evidence points to warming being natural and cyclical and the CO2 is a BYPRODUCT of warmth because the ocean sink releases the gas.
Obviously, there is scientific evidence that PART of the warming is anthropogenic...and it isn't conclusive that CO2 doesn't contribute. However, the degree of statistical certainty is NIL, yet politically and idealogically motivated scientists have plotted (read the e-mails) to cover up, hide the uncertainties, rewrite history and play down earlier warm periods, and falsify and skew statistical data in favor of showing warmer trends than really exist. The e-mails tell it all, and all the key players, American and British scientists, (Michael Mann, Phil Jones, Keith Briffa, William Connelly, Gavin Schmidt, James Hansen) etc are involved. Paleo-climatologists working with tree rings, their bread and butter, have used deceptive "tricks" to make their data seem more significant and trustworthy than it actually is. Other proxies are used but they are not as easy to calibrate and correlate and they also don't "line up" as convincingly with statistical manipulation to "erase" the earlier warm periods from paleo-history.
Without true statistical significance in the warm trend we are experiencing, or in historical "records", there is no way to ascertain with any certainty if it isn't "normal". But they don't want you to know that, or else their "consensus" would be exposed as the sham that it is.
Should we cut back petroleum dependency? Yes. Should we be looking for cleaner alternatives? Yes. But not outside of the natural advancement of technology. We don't want our economies crippled paying 5 times the current cost for clean energy technology that hasn't advanced far enough along to be economically feasible.
