Anything new to see here?

The Nested Black Body Shells Model & Extreme Greenhouse Warming

The reason that the surface of the Earth is about 33 K warmer than the effective radiative temperature of the Earth system as a whole as seen from space is because most of the energy dissipated by the Earth’s surface and through the troposphere (the lower atmosphere) is transported upward by a combination of water evaporation and convection. It is very important that transport by thermal radiation is a much more minor actor in the transport of heat in the troposphere. It is critically important that most of the Earth’s heat is radiated to space from the upper part of the troposphere which is at temperatures that are close to those of the Earth system as observed from space. This actually forces the air at the altitudes where most of the radiation to space occurs to be near and slightly lower than this low effective radiative temperature of the Earth system. Once that is a given, then the temperature gradient in our troposphere due to the Earth’s gravitational field dictates the surface temperature with adjustments due to such cooling mechanisms as convection and the effects of the water cycle and clouds.

Nothing new - it is back to The Gas Laws set the lapse rate logic that strangely some physicists and mathematicians find hard to accept as shown for example in many threads in WUWT. Yet the lapse rates for the ICAN standard atmosphere were calculated using just The Gas Laws - but then they were developed for flight safety and not by academics.
