"The theory of Global Warming assumes that CO2 is an atmospheric greenhouse gas and as it increases temperatures rise. It was then theorized that since humans were producing more CO2 than before, the temperature would inevitably rise. The theory was accepted before testing had started, and effectively became a law. "
Perhaps someone can produce the data that has shown Carbon Dioxide as the driver ever in our climate history. Surely this isn't something that is merely assumed is it?
This figure shows the variations in concentration of carbon dioxide (CO2) in the atmosphere during the last 400 thousand years. Throughout most of the record, the largest changes can be related to glacial/interglacial cycles within the current ice age. Although the glacial cycles are most directly caused by changes in the Earth's orbit (i.e. Milankovitch cycles), these changes also influence the carbon cycle, which in turn feeds back into the glacial system.
Since the Industrial Revolution, circa 1800, the burning of fossil fuels has caused a dramatic increase of CO2 in the atmosphere, reaching levels unprecedented in the last 400 thousand years. This increase has been implicated as a primary cause of global warming.

The fact that Dr. Timothy Ball may be receiving funding from the Oil Industry does not in itself prove that everything he says is incorrect.
Turn matters around, and imagine yourself as a supplier of a product that has attracted negative publicity:
- publicity that you know to be misleading (or maybe just outright bl---y wrong!)
Would you then be acting improperly if you hired expert opinion in to set the record straight on your behalf?
Furthermore, would any positive thing that that person said be automatically wrong, just because you were funding the project?
Likewise with the matter of Global Warming / Climate Change.
Opinions from the likes of Dr. Timothy Ball cannot be dismissed, just because he may have received some funding from oil companies.
To get a full handle on this matter, one has to dig a bit deeper than that.
Please note that I am not here necessarily agreeing with all he says:
- just pointing out that it is surely a rather short sighted approach to automatically reject any contrary ideas Dr. Ball puts forward about Climate Change, merely because he may have received funds from the Oil Industry!
Jack.
NB:
Bearing in mind that this is a discussion about Global Warming / Climate Change
- not cigarette advertising.
So Swalker,
In the 400,000 years of Vostok ice core data, do we ever see CO2 causing temperature rise? Or do we see it as a response to temperature rise?
If not a cause, then what made CO2 rise?
What was a cause?
