Gordon Andelin:
I provide my answers to your questions.
Q1.
GHG predicts that the troposphere should be warming as a result of increased CO2. It is not warming. This, according to UAH and RSS satellite measurements.
A1.
Correct. This is explained and referenced in the NIPCC Report that is at
Q2.
The oceans should be warming as a result of increased CO2 and they are not. This according to measurements taken by ARGO ocean going temperature sensors for the past 5 years.
A2.
Correct. But, as always, what this means is open to interpretation. A good summary of the pro-AGW ‘take’ on this for non-scientists is at

Q3.
I asked this question in an earlier post: Do the GCM’s only consider unproven positive feedback in the climate system without including any negative feedbacks.
A3.
The answer depends on how you define “feedback”. Please note that climate modelers do not use the term ‘feedback’ to mean what control engineers do. For climate modelers a positive feedback is enhancement of AGW and a negative feedback is a negation of some AGW. The most significant climate model feedback is the assumed increase of water vapour in the atmosphere with higher temperature. Water vapour being by far the most powerful GHG this is assumed to provide an enhancement of the increased warming from atmospheric CO2. Indeed, without the water vapour feedback (WVF) any warming from increased CO2 could only be trivially insignificant. Although unproven, the WVF is probably correct. However, it is assumed that sulphate aerosols cool the Earth (a debatable point but I here ignore that debate) and the WVF would therefore cool the modeled Earth (negative feedback).
I hope this is what you wanted.
