Sources and graphs would be appreciated. Does any one have data on CO2 concentrations during this time period?

Please ping me if you get a response because the manmade link is the important part; logic and hard numbers are rare with this topic.  The NYTimes readers responding at the end of this piece felt the graphic vindicated the IPCC's predictions.  This proves that the NYTimes is good at selling newspapers, and whether they're talking cooling or warming, it's the sun and not CO₂  (manmade or natural) that relates to the anomaly.

CO2 levels linearly increase with time, with a very slight but measurable oscillation each spring to summer period as plant life increases (in the northern hemisphere.) This increase in plant life reduces CO2 by a predictable amount. Note that the INCREASE in CO2 of 30% since the first measurements in 1970's HAS NOT meant an increase in temperatures - past the cyclical 1/2 of one degree that naturally occurs. That is, if Kyoto is so vital that "freezing" CO2 levels at their present levels is so important, then the predicted temperature increase would be limited to LESS THAN 1/10 of ONE degree. Yet we have a natural oscillation of 1/2 of one degree.

Further, a KNOWN increase in CO2 of over 10% (from 1996 through 2008!) has NOT meant any detectable increase in temperatures!

At stations in the southern hemisphere (with an opposite winter-summer growing period) the same slight CO2 oscillation happens, but in the reversed months.

What has ONLY happened in the 1972-1998 period is a increase in CO2 with an increase in temperatures: at EVERY other period since 1890’s, temperatures have NOT tracked with CO2: temp’s go up, CO2 remains the same; temps go down, CO2 increases; CO2 increases, temps stay the same.

Pick ANY 27 year period since the 1990’s, and the CO2-temperature relationship can be ANYTHING you want it to be.

Comment# 29 has a graph of CO2 versus time.
