Simply looking back you can see no direct link exists. skepticsglobalwarming.com worldclimatereport.com junkscience.com Earth's atmosphere today contains about 380 ppm CO2 (0.038%). Compared to former geologic times, our present atmosphere, like the Late Carboniferous atmosphere, is CO2- impoverished! In the last 600 million years of Earth's history only the Carboniferous Period and our present age, the Quaternary Period, have witnessed CO2 levels less than 400 ppm. There has historically been much more CO2 in our atmosphere than exists today. For example, during the Jurassic Period (200 mya), average CO2 concentrations were about 1800 ppm or about 4.7 times higher than today. The highest concentrations of CO2 during all of the Paleozoic Era occurred during the Cambrian Period, nearly 7000 ppm -- about 18 times higher than today. The Carboniferous Period and the Ordovician Period were the only geological periods during the Paleozoic Era when global temperatures were as low as they are today. To the consternation of global warming proponents, the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today-- 4400 ppm. According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. Clearly, other factors besides atmospheric carbon influence earth temperatures and global warming.

How about that melting arctic ice - no change in the last 28 years - bet you didn't know that. globalwarminghoax.com Satellites first started taking measurements of sea ice in 1979-1980. After 28 years of warming Arctic sea today is where it was when measurements started. Will we see news photos of Polar Bears frozen to the ice? Where is the media now that the Arctic ice concentration is at the same thickness as when measurements began 28 years ago? How many years of normal ice conditions will it take before they admit the Polar Bear isn't threatened? The coverage of both Arctic and Antarctic ice has been very one sided. Arctic Ice Concentration for May 1980 and May 2008 From the National Snow and Ice Data Center, University of Colorado Note that the total is 10.9 million square kilometers for both years. All the while CO2 levels have gone up. At the other side of the planet the Antarctic is still experiencing record ice. Since 1980 total ice concentration is up 35% and ice extent is up 21%. From the National Snow and Ice Data Center, University of Colorado Where is the media on this? If the Antarctic ice was down 35% it would be headline news for weeks and Congress would probably have passed the cap and trade legislation. But the popular news media is no where to be found on this. We're not even hearing how happy the Polar Bears are or whether we're getting a good bunch of bear cubs out of it. Could be that good news is never welcome news to the those wishing to use this issue for their own political agenda?
