Not “Watt is energy”. In physics, and what should be everywhere else in anything calling itself science, what is the unit of energy? The unit of energy has a name, and it is called a Joule, after English physicist James Prescott Joule. A Joule, or Joules, are the unit of energy in science. There are other equivalent metrics for energy such as “ergs” or “electron volts” but they are all equivalent to a certain number of Joules.
Watts, on the other hand, are a unit of flux. In particular, the temporal flux of Joules, meaning the number of Joules being “used” or “passing by” in one second. The fundamental definition and unit of a Watt is a Joule per second, so, W = J/s where the letters abbreviate the relevant quantities. So, one Watt is one Joule of energy used in one particular second. We call this flux.
When we get to radiation or light, and the measure of its strength, these are measured in Watts per square meter, which means Joules per second per square meter, and this is called flux density. It is a number of Joules, being used each second, over the area of a square meter. W/m2 = J/s/m2. These are the units for the Stefan-Boltzmann Equation which is the single equation that exists for converting radiation, or light, into temperature. Why I mean by that is that the equation tells you the temperature of the light given its intensity, or conversely, the intensity of the light given its temperature. The equation tells you that light has a direct equivalence to temperature, just like mass has a direct equivalence to energy. The latter equation is Einstein’s E = mc2, which shows that mass has an equivalence to energy. Likewise, radiation has an equivalence to temperature via the Stefan-Boltzmann equation, which is F = σT4, where F is the Flux density of the radiation, σ is a constant, and T is the temperature.
So then what’s wrong with the IPCC energy budget? Let’s have a look at it again (see diagram):
What they’re doing to get this thing to “work”, is adding together the flux densities of light. Given the Stefan-Boltzmann equation which shows us that light flux density has an equivalence to temperature, then what this diagram is doing is adding temperatures together, to make it work. When it adds 168 J/s/m2 from sunlight with 324 J/s/m2 from the atmosphere, it is saying that sunlight is -400C and that the atmosphere is 1.80C (because that is the equivalent temperature of those light flux densities), and that if you add together something that is -400C to something that’s +1.80C, you get +150C. Not just that – the diagram tries to say that air is hotter than sunlight!
