The older CO2 measurements are thought to be inaccurate due to the scientific instruments used, improper procedures etc.

[Robert A Cook PE]

Sobering: I did NOT realize that "global warming" theorists had been so fixed in their methods and prejudices as early as the 1940's and 1950's!

[Robert A Cook PE]

Not true: This writer shows that they ARE NOT inaccurate and that they DID use valid procedures. Wiping them away by massively classifying them as inaccurate is the method used by Callender to promote HIS theory.

You statement is flatly contradicted by this research, and by Callender's prejudices.

I no longer trust anybody discussing items that would tend to be supportive of the CO2 Global Warming hypothesis ... after the shameful inclusion of Mann's "hockey stick" in the IPCC reporting.

Good article. Here is another paper that questions pre-industrial CO2 levels as measured from ice cores. Essentially, it says that at deep depths, the ice bubbles are under pressure, and that the drilling process is vulnerable to the escape of portions of the gases as they are being brought to the surface where the pressure is much less. Here is the article:

from 2001:

The Atmospheric CO2 and Temperature Records
of Dome Concordia, Antarctica

the "main feature" of their CO2 record is the 40% increase from a mean value of 189 ppm around 17,000 years ago to a mean value of 265 ppm around 11,000 ago. Furthermore, close examination of the rise in temperature and atmospheric CO2 concentration at the end of the last glacial maximum (based upon a linear fit of the data) revealed the increase in temperature took place at 17,800 ± 300 years ago, while the increase in CO2 took place at 17,000 ± 200 years ago. On this basis, the authors conclude that "the start of the CO2 increase thus lagged the start of the [temperature] increase by 800 ± 600 years."

It discusses the carbon issue and your graph should come handy, if you care to share it. Especially, against the pro global warming arguments presented by one Freeper.

[beebuster2000]

science may yet triumph on this issue.

here's hoping

[ken21]

the pursuit of the truth has never been one of al gore's desires.

[GreyFlcn]

Put it this way.

Even Martin Durkin, the producer of “The Great Global Warming Swindle” agrees that the CO2 rise was caused by industrial emmisions.

even martin durkin didn’t mention

volcanoes.

I realize that since Gore is the most outspoken advocate of the global warming debate, however, I am very curious what the reactionary right doesn’t attack say James Hansen or any of the dozens of other researchers? why is Gore your target? why not one of the europeans of asia researchers?
just wondering
