In 1993 the Cambridge University Press published the “Atlas of Satellite Observations Related to Global Change” edited by Robert J. Gurney, James L. Foster, and Claire L. Parkinson.
Perhaps, with hindsight, this book represents the “golden age” for Climate Science when the discoveries of the “satellite age” provided many new insights – such as the Earth’s Albedo and the Net Radiation Balance for the Earth.
The global annual averaged albedo is approximately 0.30. The annual average albedo of the northern and southern hemispheres is nearly the same, demonstrating the important influence of clouds.
The difference between the absorbed solar energy and the OLR is referred to as the net radiation. The annual variation in net radiative energy follows that of the solar declination due to the annual variation of the incoming solar energy being greater than the annual variation of the albedo.

This wonderful tome contains a chapter on the “Radiation budget at the top of the atmosphere” written by Edwin F. Harrison, Patrick Minnis, Bruce R. Barkstrom and Gary G Gibson which includes a “Radiation balance of the Earth” diagram.
This is the earliest “radiation balance” I have stumbled across and provides a wonderful baseline against which we can evaluate the wonderful achievements and advances made by Climate Science in the last twenty years.

Clearly, there have been some serious “changes” in the last twenty years.
These changes reflect the evolution of Climate Science from “Global Change” through “Global Warming” to its current “Climate Change” headline message.
Interestingly, the changes suggest the Earth’s surface is a colder place to live because the planet is absorbing 17.10 W/m2 less whilst reflecting 6.84 W/m2 more from the surface and emitting an additional 10.26 W/m2 from the surface directly to space.
Unsurprisingly, there seem to have been a lot of changes in the flows of energy from the Earths surface into the atmosphere. Unfortunately, these changes appear to reflect “human invention” rather than refined observational data.
These heavy handed changes made to support the myth of “anthropomorphic global warming via back radiation” have resulted in a lot less [23.94 W/m2] latent heat being transported into the clouds [with a corresponding reduction in emission by clouds into space of 20.52 W/m2] and a lot less [30.78 W/m2] surface emissions into the “not-clouds” atmosphere.
There used to be a joke about putting your watch back 20 years when you landed in New Zealand. Times have changed. Now it’s best to put your watch back 20 years when landing in the swamp of Climate Science.
