About those climate models ...

... Numerical Models, Integrated Circuits and Global Warming Theory. (Hat tip, Dave Lull.)

The fact that these artificial "climates" are closed systems far simpler than the global climate, have the advantage of the experimental method, and are subject to precise controls, and yet are frequently wrong, should lend some humility to those who make grand predictions about the future of the earth's atmosphere.

    The author of the piece from which you quote seems to have missed the point completely.

  2. How so, Maxine? If you cannot predict accurately when you have greater control and certainty regarding the data, how can you hope to predict accurately when you have lesser control and accuracy? His point seems to be much the same as Freeman Dyson's regarding climate models. Also, it would seem that insofar as we have been able to back-check as it were certain climate predictions, they have been wrong. There certainly doesn't seem to have been much warming so far this century, and certainly not lately in this country as
    this chart indicates.
