We have more than 800,000 years of data showing a rock solid correlation between CO2 levels and global temp.  But you believe that this correlation has decoupled in the just the last 19 years?
No, it hasn't.  Yes, CO2 has shot up faster the global temps (thank god) but temps will follow as sure as they have reliably for the last 800,000 years.  The resolution of our temp/CO2 record likely doesn't show lags on the scale of 20 years (or more) but the fact remains that CO2 is a huge forcer of global temps.  

Two more questions: Is it possible that ANY scientific data COULD convince you that that (a) the Earth is warming and (b) humans are largely responsible for it?
