Mann also states that the models agree with observations (they don't).
Q: How do we know the warming is due to CO2? Well, because the failed models say so. And the models predict more warming at the poles and that's what the thermometers show (but we won't mention that we have cherry picked stations that show warming out of ~20 in the arctic and extrapolate arctic temperatures from much lower latitudes).
Gore would be proud that they use the same trick of showing the temperature v. CO2 ice core data without mentioning that temperature leads CO2 levels by ~800 years:
The videos also have a host of other misrepresentations, including stating that the model-predicted tropical tropospheric hot spot has been observed (it has not), that only by including CO2 (imaginary) positive feedbacks can models predict temperature (without including any consideration of ocean oscillations, clouds, water vapor effects, etc.), and many others. Sad day for science.
