IN THE CLIMATE MODELS: Where's the hot spot?

If an engineer built an aeroplane and said it could fly 600 miles and the thing ran out of fuel at 200 and crashed, he wouldn’t say ‘Hey, I was only off by a factor of three’. We don’t do that in engineering and real science.

Conclusion: "A model is a theory, a hypothesis. A model that is falsified by observation is a wrong hypothesis. That really is all there is to it."
