I keep on pointing out the problems of gh-theory;


How hard can it be

”If we then increase atmospheric CO2, while leaving everything else unchanged, that will act to block some of the outgoing flux. What essentially happens is that some of the flux will end up coming from higher in the atmosphere that it did when atmospheric CO2 was lower. Since the temperature drops with altitude (in the troposphere) this means that it will now be coming from regions that are cooler and that, hence, emit less. Therefore, the outgoing flux goes down and the system will have to warm to return to energy balance. As already pointed out, doubling atmospheric CO2 is estimated to reduce the outgoing flux by about 3.7Wm-2.”

The bold part is at the core of the problem. This is a completely backwards statement, a demonstration of the lack of understanding in thermodynamic relationships. ”The outgoing flux” is the ”flux density” which is equal to the emissive power of the body via T^4. A body does not have any possible way to compensate for a dropping flux density from any part of the system, if there is not an increasing power density from the heat source. It just simply drops in temperature in that part, and the source must increase the transfer rate to keep a steady state. Since heat flow from both the sun and the internal generation is constant, there can not be any increasing temperature anywhere.

You cannot ”block” heat by increasing the rate of heat transfer via dropping temperature of the absorber, that is the opposite of ”blocking heat”,

One can only ask these people to study heat transfer and heat engines carefully. Only when they understand that, they will know why they are wrong.
