The NASA Flow Chart — Energy Budget

Explanations Here

 

New NASA Model, identical to the Kiehl-Trenberth model with minor updated numbers—shows 79% radiation leaving the surface, as Kiehl-Trenberth model does.

 

 

Outdated NASA Model—shows 41% radiation leaving the surface.

 

 

Sometime after Kiehl-Trenberth published their model in 1997 showing 79% of the energy leaving the surface of the earth being in the form of radiation, with only 21% being due to conduction, convection and evaporation, NASA produced a model showing 41% radiation instead of 79%. Why? Presumably, trying to regain some credibility, since 79% radiation is too absurd for any scientist to believe. Only white hot metals in a vacuum could emit 79% radiation, not the surface of the earth.

But recently, NASA produced a new model with approximately the same numbers as Kiehl-Trenberth, showing 79% of the energy leaving the surface of the earth as radiation. A few other trivial changes were made for the claimed purpose of updating.

Why did NASA recently cave to the ridiculous 79% radiation? One reason might have been the fact that science is never wrong, and Kiehl-Trenberth published so long ago that their model is incorporated into IPCC reports. More importantly, Kiehl-Trenberth used the Stefan-Boltzmann constant to derive their number. To reduce the radiation to 41%, as NASA originally did, is to defy the Stefan-Boltzmann constant, which is not what science does.

What this shows is that the Stefan-Boltzmann constant is so ridiculous that it will not produce a credible result. It's either correct the Stefan-Boltzmann constant, which will never be done after a century of use, or pretend that it is just flawless in showing the surface of the earth emiting as much radiation as a white hot light bulb.
