How about correlation between Temperature and Atmospheric Carbon dioxide?
We know that, from the Vostok Ice core data (re-graphed by Jo Nova)
Ok, Let's get a little more up to date. Here are the data for the last 10,000 years:
The bottom line is that rising temperatures cause carbon (dioxide) levels to rise. Carbon (dioxide) may still influence temperatures, but these ice cores are neutral on that. If both factors caused each other to rise significantly, positive feedback would become exponential. We’d see a runaway greenhouse effect. It hasn’t happened. Some other factor is more important than carbon dioxide, or carbon (dioxide)’s role is minor.

Not much correlation there!
And in the twentieth century, global temperature had three periods of rising temperature interspersed with periods of falling or neutral temperatures:

You guessed it! Rising at a virtually constant rate. No correlation there!
