Read here. The unbelievably expensive, wasteful climate model fiasco continues to be documented as researchers find more model failures. The latest is the finding that models are unable to correctly simulate tropical ocean temperatures. This is a major failure.
In order for climate models to even have a tiny chance at accurately predicting regional climate conditions, they need to be able to simulate actual tropical ocean warming patterns. In this peer-reviewed study, scientists determined that the IPCC climate models are unable to do so.
"The authors note that there is increased interest in the ability of climate models to simulate and predict surface temperature and precipitation changes on sub-continental scales," and they state that these regional trend patterns "have been strongly influenced by the warming pattern of the tropical oceans," which suggests that correctly simulating the warming pattern of the tropical oceans is a prerequisite for correctly simulating sub-continental-scale warming patterns...determined that "the tropical oceanic warming pattern is poorly represented in the coupled simulations," and they say that their analysis "points to model error rather than unpredictable climate noise as a major cause of this discrepancy with respect to the observed trends." And because of this problem, they found that "the patterns of recent climate trends over North America, Greenland, Europe, and North Africa are generally not well captured by state-of-the-art coupled atmosphere-ocean models with prescribed observed radiative forcing changes.""
