Oh. I always though the main controller of climate was number of mobile telephone calls per annum, since the correlation between temperature and phone use (nay, TV's if we include the 1930's - present) has increased since temperatures began to rise as a correlation to the use of these instruments' increase. Since the ghg's are an unreliable source of climate forcing, particlarly CO2, due to its peripheral-non-existent magnitude on the climate, then by a process of elimination, it MUST be the correlation between temperature and increasing use of TV's and phones.

I'm working on a model that will conclusively and indisputably show that the sharp increase in the numbers of crooked politicians and activist scientists is unequivocally responsible for the earth warming :).

Computer generated model of Earth's temperature control knob

The first step should be to demonstrate that the models can predict the past climate of the earth. What would be interesting, for example, would be to see a climate model which can prove or disprove the existence of the MWP and explain its cause, or lack of existence. (If anyone knows of such a model validation, please let me know).

Comments:

Using climate models which have been tuned for high sensitivity to carbon dioxide, it has been found that climate models have a high sensitivity to carbon dioxide. That's SCIENCE!

Boy, is the sun going to be disappointed, all this time it thought it had the most input.

Plants and oceans "condense" CO2 constantly and abundantly. What planet are these guys on?

Not more climate model evidence. These people have just proved that they are not scientists.

It is truly amazing how "reputable" journals accept from some few selected fellows their trivial hypothesis and publish as a scientific paper.
This clearly demonstrates that the "peer review" system is corrupt.
Poor Gavin spends most of his time on Real Climate site and other fun activities and has no time for comprehensive research that we, all taxpayers, are expecting from him. The references to Fourier, Tyndall and Arrhenius look kind of sad... Is it time for us to stop paying these gentlemen their six figure salaries?
