"The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.

How could the experts have missed such a simple explanation? Because they have convinced themselves that only a temperature change can cause a cloud cover change, and not the other way around. The issue is one of causation. They have not accounted for cloud changes causing temperature changes. "

From Dr Spencers new book.

Ayep........Dr. Spencer does have it figured out.

The AGW climate scientists also have this problem of viewing aerosol forcing as identical to CO2's potential radiative forcing. Entirely different mechanisms are likely to cause entirely different behaviors.

They also seem to ignore that MOST of the energy of the atmosphere is actually radiated by water vapor and clouds (clouds through black body radiation). Because of this, the increases necessary to offset any CO2 absorption are far lower than would be suggested by the raw CO2 absorption.
