That was an interesting talk muf, but you'll notice that this area of science has more questions than answers. In fact Jasper clearly stated that his presentation wasn't any kind of submission, but just observations to be noted for future reference.
I'd like to refer back to your post of May 31/2010.
"Temp goes up cloud cover goes down, no-brainer really"
It's true that the amount of 'water vapour' (WV) that air can absorb increases with temperature, implying that clouds evaporate as temperatures increase, but that's only part of the story. A cloud just 'hangs around', drifting in the atmosphere and causing a shadow on Earth's surface, until it either precipitates as rain or evaporates to WV again.
Any water that precipitates from cloud has 'lived its lifetime' in the atmosphere (ignoring evaporation from the 'raindrop' as it falls) and this 'average lifetime' is accepted to be ~9-10 days from evaporation at Earth's surface to precipitation back to Earth's surface again. However, WV is a 'lighter than air' gas and any evaporation of cloud just results in WV migrating to higher, and cooler, altitudes where it condenses to cloud again. Thus, maintaining a degree of cloud cover. Precipitation is the only way to end WV's survival in the atmosphere.
There's an important point to be recognised here. Earth's surface is normally the hotter between Earth's surface and Earth's atmosphere. This strongly suggests that surface temperature drives the atmospheric region of the hydrocycle and thus cloud formation. When surface temperatures are high we see a scenario where the atmosphere is 'loaded' with greater quantities of WV and 'cloud cover' is increased as a result on a ~9-10 day rate. When surface temperatures are low we see a scenario where the atmosphere is 'loaded' with less quantities of WV and 'cloud cover' decreases, again, on a ~9-10 day rate.
This posits 'cloud cover' as the primary 'thermostat' for average global temperature, as it reflects insolation with a ~9-10 day sensitivity and is temperature dependant in a negative form with temperature increase.
