Man Made Global Warming Easily Disproved

There are three possible explanations for the statistical correlation between CO2 levels rising and Global Mean Temperature rising during the 20th Century.

One: CO2 causes Global Mean Temperature to rise.

Two: Rising Global Mean Temperature causes CO2 to rise.

Three Both CO2 and Global Mean Temperature rose independent of each other during the 20th Century.

Using the process of elimination, we can easily eliminate item one because temperatures have stabilized and even dropped slightly after 1998 while the level of CO2 continued to rise.

We can eliminate item two since we know that human activities has increased CO2 levels in the atmosphere.

Therefore item three must be the correct answer.
