I referred (in Dutch) last week to an interesting op-ed of Ross McKitrick on the regional performance of climate models. In that post he mentions an upcoming paper. That paper as well as a press release are now put online on McKitrick’s webpage.
The paper is a logical next step following several papers in which McKitrick showed that surface temperatures on land have a warm bias due to socioeconomic effects. In the new paper he looks how good different climate models are in reproducing regional temperature changes. It won’t surprise many that the models are not so good. The paper shows that a very simple economic model made better predictions.
