Global Warmth, Part V

Here is an article that explains one of the problems with the junk science that is global warming. The present hysteria is based on carbon dioxide levels that are based on flawed science. :
"Global warming alarmists, however, prefer to estimate pre-industrial CO2 indirectly by means of ice cores, from which they derive the much lower pre-industrial revolution estimate of 280 ppm. The lower estimate makes industrial-era greenhouse gas emissions appear to be dramatically higher.
But Dr. Jaworowski says that the ice core-based CO2 estimates are unreliable.
First, ice core-based CO2 estimates vary even more than the 19th century direct measurements, generally ranging from 160 ppm to about 700 ppm with some readings as high as 2,450 ppm. But because the higher estimates are politically incorrect – that is, they don’t support the notion of manmade global warming – Dr. Jaworowski says they haven’t been mentioned in the published scientific literature since the mid-1980s when global warming fever began to spread."
