1) Demonstration that the magnitude and rate of change of temperature is unlike anything that has ever been experienced on this planet.
That it may have happened before naturally without man’s hand doesn’t mean that it can’t happen with it. To argue that it does mean this is to argue that since deer died naturally before humans were around, humans are not capable of killing deer.
Maybe what you mean is "demonstration that the magnitude and rate of temperature change is not explicable through known natural means"; in that case I would fully agree that this is a critical demonstration to make. But to demand that a similar magnitude and rate should never have happened before does not make sense to me.

2) Demonstration that temperature change follows lock-step with CO2 concentration throughout geologically-comparable time, excluding the natural cycles (AMO, PDO, ENSO, Milancovich, etc) with CO2 being the leading and temperature being the lagging indicator.
This was already shown LONG ago to not be the case, at least over the past ~500K years—it is accepted by every climatologist out there that CO2 lagged temperature rises by about 800 years, and this point is not in any way inconsistent with AGW.
CO2 acts as both a feedback and a forcing. In the past it was a feedback, because the only natural means by which CO2 could possibly increase at regular geological intervals was through a temperature increase. Temperatures began to rise, and 800 years later CO2 followed. The temperature rise lasted for about 5,000 years, which mean CO2 was a factor for 5/6 of the temperature rise; it was just the beginning 1/6 that was caused by something else.
CO2 was a feedback because it is a proven greenhouse gas, and because it is naturally released during a warming climate due to Henry's Law. To demand that the Earth should have had some mechanism of releasing CO2 at regular intervals independent of temperature changes is to demand a mechanism currently totally unknown to geology—and therefore, probably doesn’t exist. But I really don’t understand why it needs to exist.
Not to mention that “Demonstration that temperature change follows lock-step with CO2 concentration throughout geologically-comparable time,
excluding the natural cycles” is a rather odd statement. If you are talking about geological timescales before human intervention, how the heck could they be
anything but “natural”? Are you saying there should be geological evidence of AGW before AGW ever existed?

3) Demonstration that we understand how the above-noted natural cycles work and influence the surface temperature.
ENSO, PDO, Milankovic, and solar cycles are all included in calculations of warming. They have all been ruled out. A long time ago. That’s why climatologists are convinced there is a non-natural cause to the recent warming.

4) Demonstration of all of the above without resorting to computer simulations.
All we have is empirical data through proxy records and (relatively) recent observations, and theoretical calculations based on concise laws of physics. Unless you are demanding these calculations be done with slide rule and chalk board, I don’t understand what your aversion is to using computers for the latter piece.

5) Use of air enthalpy (including humidity effects) when measuring the energy of the atmosphere, and not temperature.
Specific humidity is measured on the long term global scale. Temperature is measured too. You have everything you need to calculate total enthalpy through time over the past couple of decades. Knock yourself out.
But as I already pointed out, total energy change of the atmosphere is over an order of magnitude less than the total energy change of the ocean. That’s why it’s not talked about as much as you would like: because if you’re going to talk about total energy, it’s oceanic energy that dominates the discussion.

6) Experiments (not computer simulations) that demonstrate the feedback effects of clouds - at least the first and second derivatives of temperature with respect to cloud cover.
Terrific idea (really!) How might such an experiment work?
Really, I would love to see more experiments. I’m just inclined to think that there is some difficulty with carrying them out in a meaningful way, and THAT is why they are not more common.
I mean it’s hard to control something as big and open as the atmosphere, so designing something that is beyond the class of mere observation and more of a controlled “experiment” seems quite difficult. But, again, it sincerely sounds interesting and I would love to hear your thoughts of how it could be done. I would even be interested in personally contributing my free time to help the experiment (really).
Perhaps we and others here can put our minds together and find a truly unique way to contribute to the field of climatology.
