IPCC forecasts useless according to forecasting expert

A quick summary of a summary....

Forecasting Guru Announces: “no scientific basis for forecasting climate” « Watts Up With That?

Today yet another scientist has come forward with a press release saying that not only did their audit of IPCC forecasting procedures and found that they “violated 72 scientific principles of forecasting”, but that “The models were not intended as forecasting models and they have not been validated for that purpose.”.....

Dr Armstrong provides the following eight reasons as to why the current IPCC computer models lack a scientific basis:
1. No scientific forecasts of the changes in the Earth’s climate.
2. Improper peer review process.
3. Complexity and uncertainty of climate render expert opinions invalid for forecasting.
4. Forecasts are needed for the effects of climate change.
5. Forecasts are needed of the costs and benefits of alternative actions that might be taken to combat climate change.
6. To justify using a climate forecasting model, one would need to test it against a relevant naïve model.
7. The climate system is stable.
8. Be conservative and avoid the precautionary principle.


While I disagree with the first sentence in this article (sir, CO2 is a pollutant, just as are feces, notwithstanding that feces are also important fuels, crop fertilizers, etc.) the rest is interesting with some facts I had not known -
