Dr. Judith Curry, IPCC scientist and Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, asks some tough unanswered questions of climate science and the IPCC in her new blog post What can we learn from climate models? The post begins with a sobering Short answer: I’m not sure.
This is interesting in light of the fact that essentially all of the IPCC 'consensus,' conclusions, and predictions are based entirely upon computer models. In addition, the IPCC admits in the fine print that said models have not been validated and that they don't even know how to validate the models.
Other tough as yet unanswered questions include:
How did they [climate scientists] manage to reach conceptual consensus in spite of persisting scientific gaps, imminent uncertainties and limited means of model validation?
Why, to put the question differently, did scientists develop trust in their delicate model constructions?
