Slide 16 in this series.
In this the third model ENSO or the ocean cycles coupled with volcanos and solar intensity provide a statistical fit that is quite good in describing temperature. Also in the attempt to analyze the statistical importance of CO2 as a variable drivn temperature, it showed that CO2 is not relevant statisitcally. Putting in total solar intensity shows that CO2 is not a driver of temperature..
NEXT: Sunspots however do show strong relevance to temperature.
The topics cover a wide range of material on the GCM climate models.
