Steven, science is about specifics, so every kind of warming cannot confirm your hypothesis, or you have no hypothesis at all. It is funny that I should have to explain AGW, but AGW says every GHG molecule begins to act as soon as it enters the atmosphere. Slow build up of GHGs implies slow warming.
You can introduce secondary mechanisms to make the warming irregular, but if there is only this single step function then you have to explain it. You cannot just say AGW = warming and the step is warming, so consistent with AGW. It is manifestly not.
You must provide a specific hypothesis that explains how the heat does not appear for over 20 years of GHG increase, then is suddenly released by the ENSO, then once again does not appear. This is what the data says and this is what AGW must explain in order to remain viable.
