Pseudoscience may not be entirely accurate, but the basics are not tested or beyond question.
Consider what the GISS says about the greenhouse effect.
NASA GISS: Science Briefs: Taking the Measure of the Greenhouse Effect
We can to some extent measure the difference between energy in vs energy out, but it is unclear
what kind of resolution the measurements have. GISS goes on top say that CO2 is responsible
for up to 20% of the effect (the 150 Wm-2 imbalance, or 33°C.)
It is at this point where the GISS's wheels fall off the cart and they move into pure speculation.
The reason I say this is the 33°C idea has been around for over a century.
if in fact CO2 is responsible for 20% of that 33°C(6.6°C) then, all the past doubling s of CO2,
have to add up to that 6.6°C.
From the pre industrial CO2 level of 280 ppm, we have roughly 8 doubling s to get to a level of 1 ppm.
At that level, each fully equalized doubling of CO2, would be equal to 6.6°C/8=.825°C.
Generally it is understood that each Wm-2 of positive energy imbalance, will force a temperature increase of .3°C.

To get to the GISS's implied 20 W/m2, would mean the temperature would have to be 20 X .3= 6°C,
and almost no model is suggesting that ECS will be that high!
