Ou himself said that the “results show that climate models give a poor reflection of the actual changes in extreme precipitation events that took place in China” during the period he examined. “Only half of the 21 analyzed climate models were able to reproduce the changes in some regions of China,” he said. “Few models can well reproduce the nationwide change.”
Ou’s work is important. If the models can’t get the past right, how can they be trusted to predict future climate?
