Nobody seems to realize that the primary metric humanity uses to measure the global warming is irradiance. It is a 16th century methodology adapted to the 21st century.
Mankind would be bettered served by a gas filled sphere and a thermometer transmitting the temperature from L1.
The smoothing of the data makes look like surface radiation varies only slightly from season to season, and that skews the greenhouse gas equation to the right.
Irradiance fall in to the category of if the only tool you have is a hammer every problem looks like a nail.
Life exists on this planet simply because of the range of the orbit, the intensity of the sun & the liquid planet core. In an expanding universe the earth's orbit elongates, the sun dims & the core cools.
