Had Copernicus not made the compromise to predictive modelers, planetary climate would be discussed normally as the rate of change in surface condition across latitudes as our planet orbits the Sun. This rate of change is based on the degree of inclination between 0 degrees and 90 degrees - a spectrum in other words .

What is now called 'climate change' is just another symptom of wasted effort that began with the overreaching agenda of scaling experimental sciences up to terrestrial sciences and astronomy -
"Rule III. The qualities of bodies, which admit neither [intensification] nor remission of degrees, and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever." Newton
Want to squeeze the Earth's atmosphere into conditions found in a common greenhouse and passing speculation off as fact and that is how it is done. In typical fashion of a certain class in Britain and their imitators elsewhere, they can't walk the debacle back to a reasonable ground.
