Climate Model Status

The last and fourth report by the IPCC was in 2007.  They are getting ready to issue their fifth report in September.  The major question is how well have their models and hypotheses matched actual temperature anomalies.

Likewise, several climatologists that disagree with claims of the IPCC have made projections of their own.  How well have they done?  The following article answers those questions.

The bottom line is -- models based on CO2 as a primary driver are fairly accurate.  Those based on other drivers, such as sun spots, have failed rather significantly.
