Climate models are running red hot, and scientists don’t know why
I’m a climate change skeptic almost entirely because I don’t trust models. I believe there are too many dynamic things happening in the world for anyone to be able to predict accurately say the next 100 years (solar, earthquakes, volcanoes etc). One way to make me a believer though is an experiment: if I were to give you a 100 year stretch of history and you were able to accurately predict with the models what exactly happened in those 100 years.<p>The article talks about it a little bit about how the models are used to predict the 19th century to see if they are correct. But the models use the last 100 years as input so of course it will give you accurate output. But the real challenge of the models would be to accurately predict things that are not part of the inputs into the model. I don’t believe that these models can do this and are thus an exercise in straight extrapolation based on very complex and interconnected inputs.
