OK here we go:

1. The answer is yes. The answer yes is rendered as not relevant to the overal picture, and here is why: Do you know what is the cardinal characteristic of a type 0 servomechanism? If not I will say it in the most simplified terms possible. It contains in the feedback path, or forward path, a single-pole time integration. This means that in the case of a system, say a motor controller so characterised, if you put a step torque load on the shaft, the speed changes, but climbs back towards the regulated speed with a time profile of exponential order, with time constant chosen in the overall stability criteria determination.

Now since the earth has a closed loop regulatory system, featuring namely THE OCEANS AND WATER VAPOR, the ability of water vapor to regulate atmospheric temperature has never been in doubt. Since water vapor is thousands of times more effective at modifying atmospheric temperature than CO2, that it is proposed in most of the published papers attacking AGW theory (I’m sure you guys know this since of course you are familiar with all of these papers) that the earth approximates a type 0 feedback control system, in its ability to cancel any load change introduced by CO2 into the system.

A quantitative analog, engineering wise: pure time integration is not physically possible because of the requirement of infinite gain at the origin, but since gains of greater than 10^7 are achievable, type 0 behavior can still be assured because of the high number. In the ecological system, since water vapor is thousands of time more effective at heat regulation than CO2, this is high enough to approximate a type 0 system.

2. The answer is yes.

3. I am denying no such thing. There obviously WAS an ice age.
