That change in the rate of energy flow through the Earth system serves to keep the Earth system energy content at equilibrium despite changes in solar input or changes in greenhouse gas quantities.

The only reasonable conclusion to be drawn from the above is that CO2, volcanic outbreaks and El Nino events have little or no effect on the background temperature trends in stratosphere and troposphere because of the ability of the Earth system to change the height of the tropopause and the size and location of the permanent climate zones to change the speed of energy flow through the Earth system and thereby negate any such effects.

While a global temperature metric for the near - surface tropospheric temperatures is awkward in that it does not account for changes in local climates, it is useful from the most important and broad perspective... as one more metric to indicate total energy flow in and out of the Earth system.

This is because the fundamental problem concerns the way GHG emissions affect the flow of energy through the climate system, and temperature is just one of many forms energy takes.In the long term, the earth must shed energy into space at the same rate at which it absorbs energy from the sun.

As man start to tech up with fire, cooking, warming, pottery, field clearing, charcoal making for metals, we started to deforest the Earth and the worldwide net effect was to change the weather flows as the standing columns of water know as trees where cut down and burned to change the heat absorption properties of the Hydrothermodynamic system of the Earth.

There is a small effect from the radiative properties of the «GHG's», but they simply act as a sort of hybrid thermal / optical delay line which delays the flow of any single photon through the Sun / Earth / Atmosphere / Universe system by causing it to make multiple «bounces» through the system: surface / GHG / surface / GHG / escape to the energy free void of space.

Biogenic gases in the atmosphere play a role in the dynamics of Earth's planetary radiation budget, the thermodynamics of the planet's moist atmosphere, and, indirectly, the mechanics of the fluid flows that are Earth's planetary wind systems.

Let us remember the importance of fluid flow from less infrared transparent regions (the lower troposphere) to more infrared transparent regions (the upper troposphere) in determining the amount of energy emitted out of the earth system.

The Earth system is then a black box where you have no way of seeing what happens in the box, but simply have to follow the energy flows in and out of the box.

more carbon dioxide in the lower atmosphere means more little «point sources» for more absorbed EM in the infrared part of the spectrum, (infrared that re-radiated from the earth's surface after sunlight hit it and got absorbed); and since point sources radiate in a spherical pattern, that means more «back radiation» to earth, on balance... and this changes the «standing pattern» of energy flow in and out of the earth system, creating a time differential, so it starts to re-adjust...
