Potential temperature

I've tried to stay off posting about 'climate science' because I lost my audience months ago, but I still keep digging in my own time. I stumbled across another meteorological concept recently and added another paragraph to my summary on why the Earth is 33K warmer at sea level than its effective temperature (the temperature we would expect from incoming solar radiation and 'albedo' alone). The starting point is to realize that the average temperature of the atmosphere = the effective temperature.

The Holy Trinity of basic atmospheric physics are (is?) three formulae or concepts. ...
