Testimony on the Scientific Method Applied to Climate Model Projections

March 29, 2017

When climate model projections are tested against real world data, the model’s outputs fail to match observed phenomena and measurements, and thus should not be sued to shape climate policies.

John Christy notes “science” is not a set of facts but a process or method establishing a way for humans to discover information in the pursuit of understanding and knowledge. “In the method, a ‘claim’ or ‘hypothesis’ is stated such that rigorous tests might be employed to test the claim to determine its credibility. If the claim fails a test, the claim is rejected or modified then tested again.”

When climate model projections are tested or compared to actual observations and measurements, the model’s outputs fail to match observed phenomena and data, and as such should not be sued to shape climate policies. The average outputs of the models grossly misrepresent climate variations and changes of recent decades.
