Pink Eddy Cycle Climate Cooling Comes ...In 2150 A.D.

It depends on the interference and the intermodulation of the 4 dominant solar cycles :

1. 90 year Bleu "Gleissberg cycle"
2. 208 year Red "de Vries cycle"
3. 1000 year Pink "Eddy cycle"
4. 2500 year Yellow "Bray cycle"

It also depends on earthly cycles :

1. 24 hour day/night cycle
2. 12 month summer/winter cycle

If the atmospheric greenhouse gasses were all linear for the heat to temperature curve then it would be simpler as only interference of the 4 solar cycles and 2 earthly cycles would determine temperature in earth atmosphere.

• Daytime summer peak noon temperature TMax mainly depends on the full spectrum direct solar irradiation.
• Winter peak midnight temperature TMin mainly depends on the long wave infrared earth out radiation with the greenhouse back radiation.

Winter midnight TMin seems to follow the 90 year bleu de Vries cycle nicely going 0,2°C up and down.

Since 1980 the greenhouse midnight TMin also seems to follow the weakening solar cycles just like TMin was doing 90 years ago.

So in the winter midnight greenhouse effect, nothing has changed in the previous century although atmospheric CO2 concentration moved up dramatically since 1950 from 0,03%=300ppm to 0,0425%=425ppm.

So winter midnight greenhouse effect does not take CO2 serious as a greenhouse gas for back radiation of long wave earth out radiation ?

Anyway

In climate science there are too many unanswered questions and too many unquestioned answers ...

But : Health & Climate & Energy are really very complicated and delicate politico-scientific stuff and also socio-economic stuff but we do the best we can and try to explain it as simple as possible but not simpler than that in the group :
