Paltridge lays out the well-known uncertainties in climate forecasting. These include our inability to properly simulate clouds that are anything like what we see in the real world, the embarrassing lack of average surface warming now in its 17th year, and the fumbling (and contradictory) attempts to explain it away.

Clouds are the key to moderation of Global Temperatures. Low clouds reflect the infrared heat from the earth back to the earth. That is why with all other factors the same, cloudy nights are not as cold as a clear sky night. High clouds reflect heat back into space.

Any computer model for global warming that can not reproduce cloud formation is absolute crap and the modeling results from the program are also crap.

From the beginning the warm-Earthers knew clouds were a net negative feedback so purposely never brought them up or studied them too closely. Clouds are a powerful iris that control how much light gets in.
