The Intergovernmental Panel on Climate Change (IPCC) and its defenders often argue that critics who are not climate scientists are unqualified to judge the validity of their work and should not be taken seriously.  Basically, they argue that only climate experts can judge claims made by climate scientists.  However, climate predictions rely on methods, data and evidence from other fields of expertise, including statistical analysis and forecasting.  Thus, the work of the IPCC is open to analysis and criticism from other disciplines.

Several assessments have shown that the techniques and methods used to derive and verify the IPCC’s climate predictions are fundamentally flawed.  They indicate that the IPCC’s central claims — that the present warming trend is unusual, caused by human activities and will result in serious harm — are not supported by scientific forecasts.  Rather, these claims are opinions that are no more likely to be right than wrong.
