1) Significantly warmer temperatures on a global scale that are verifiable. (So far that is not the case.)

2) The temperatures need to be elevated for 30-years without stops and starts.

3) Those exact temperature increases need to be accurately predicted by a computer model that does not get changed to meet the new data.

4) There must be a scientifically valid and repeatable scientific experimental model that ties in man’s activities with the increased temperature.

Get those things and I will move significantly from my skepticism.

“4) There must be a scientifically valid and repeatable scientific experimental model that ties in man’s activities with the increased temperature.” (and ACCURATELY predicts present and future increases)

That’s the big one.

Occam's Razor - Solar Scientists have been extremely accurate in predicting the behaviour of the sun and the fact that we are approaching a minimum. They predict global temperatures will fall as solar activity decreases. They have been correct to this point and theirs is the simplest explanation of climate behaviour over the past 20 years.
