Some Dilemmas of Climate Simulations

"A great deal of the recommendation that the world should modify its energy infrastructure to combat climate change, costing tens to hundreds of trillions of dollars, is based on computer simulations. While this author is not what is called a ‘climate scientist’, a great deal of science is interdenominational, and experience from one field often can fertilize another.  That is the spirit in which this opinion is offered.  The author has spent a good part of his more than 50-year scientific career developing and using computer simulations to model complex physical processes.   Accordingly, based on this experience, he now gives his own brief explanation of his opinion, on what computer simulations can and cannot do, along with some examples. He sees 3 categories of difficulty in computer simulations, where the simulations go from mostly accurate to mostly speculative.  He makes the case that the climate simulations are the most speculative.

First consider the case where the configuration and equations describing the complex system are known," ...
