A good theory makes testable predictions, correct? I want to get a list going of the successful predictions made by the AGW hypothesis, because there are two pieces of data AGW completely failed to predict: the insignificant warming from 1995-present, and the insignificant cooling from 2002-present.

I've explained to you why you're misinterpreting statistical significance like 4 times, but you just seem to ignore it every time.

Ok, forget about that. List the succesful predictions AGW has made then.

Increasing atmospheric CO2 concentration, increasing global mean temperature, cooling in the stratosphere, ice loss...

How can the 'theories' have made testable predictions over such a small timeline. When do you think the models were firm enough to make such predictions? Why do you think the IPCC is now onto it's 4th report. What makes you think that the present variation is any different from any of the other drops that occurred in the past?

Er, the opening of the Northwest Passage?

That's pretty blatant, I should think.

Ahem, you asked for successful predictions?...

What can AGW Denial predict?

That there won't be a green house effect?
The carbon dioxide in the atmosphere will have no significant impact on climate, at all?!

Thanks. Hansen's prediction seems very close. Has anyone done a metastudy of predictions?
