Climate Sensitivity vs Observed
Slide 18 in this series.
Note the full range of values as seen in the models vs that observed. The observed values are less than 1C while the IPCC UN models predict values as high as 6C. Imagine that the increase in CO2 by a factor of 2X (which might not occur in this century BTW) a mere 300-400ppm could raise the temperature of earth by about 20-30%. How is that even possible> How can a trace gas do such heroic feats?
NEXT: Let us have a look at the trend of these CS predictions.
