An article in the Bangkok Post says. with respect to motoring, that "The ever increasing amount of CO2 being released is significantly increasing CO2 concentrations in the atmosphere. As a consequence the earth is getting hotter due to the greenhouse effect." (The emissions issue, Bangkok Post, September 26, 2008). These sentences summarize what has become the global warming religion preached by Al Gore and followed like sheep by the media. While it is true that the annual mean atmospheric CO2 measured at Mauna Loa has risen from 315 ppm in 1960 to 383 ppm in 2007, no theory or experiment has shown that a change in CO2 levels in this range can have a measurable effect on temperature. In actual greenhouses where they grow vegetables during winter, they inject carbon dioxide to maintain CO2 levels at 1000 to 1500 ppm during daylight to feed carbon to the plants, and that is why we call CO2 a greenhouse gas, but there is no evidence of a temperature effect of CO2 even at these high levels. The correlation between temperature and CO2 presented by Al Gore is derived from historical data and it implies neither causality nor the direction thereof. Further, the idea that the increase in atmospheric CO2 is caused by our use of fossil fuels is pure speculation and without a scientific basis.
