Dr. Ball goes on to list a series of nine problems with the reports of the IPCC, most of which were deliberate because global warming caused by human CO2 was chosen for a political agenda.

An excellent short summary of the problems and issues and well worth a complete read.

The problem is evident in the misuse of specialized knowledge by climate scientists. Using tree rings as representing temperature is a classic example.

See Dr. Ball's comments on the inappropriate use of tree rings as an indicator of summer temperature here and my response in agreement.
