People who swear by the idea that man can affect climate - may drown in their own blood in a minute. The one factor left out is proof positive that elevated CO2 does not cause Global Warming. The debate is over. A good scientist can't afford to miss this data.

If one looks at all temperature correlations and CO2 levels, there appears to be absolutely no correlation between the two variables. Granted, CO2 levels are at 370ppm right now--the highest they’ve been since 1850. But if one looks at the two above variables closely, the case can be made that the rising temperatures are actually responsible for increasing CO2 levels.

From the Scripps Institute (Mauna Loa), it can be seen that CO2 levels have increased virtually every year since 1850. But other sources---tree rings, ice cores, etc…, say that CO2 levels at earlier times have been more than 7x that of today. Per Noel Sheppard (economist; editor of Newsbusters), there have been 72 years in the past 156 (53.8%) when global average temperatures declined.

Highly correlated items will tend to follow each other, going higher or lower. But in the years that global warming alarmists use to prove this absent correlation, there was virtually no year-over-year connection between CO2 concentrations and temperature. But there are other options that should be evaluated to determine what might be causing the 0.8°C / century rise lately in surface temperature. Joe D’Aleo (Certified Consulting Meteorlogist) decided to compare the three most probable causes.
