It will be interesting to see how the Jan 2012 global temperature anomaly turns out. Jan 2011 was 0.0 C, and if the current trend contiunes until the end of the month, the anomaly could be negative.
Which is precisley what you are saying. There is absolutely no evidence that CO2 causes global warming. Assuming cliamte sensitivity is positive, the recent observed data shows that it is indistinguishable from 0.
