What is wrong ?

They call it TRP="Trend Reversal Paradox" ...

Lower solar heat input => Higher temperature ...

• In the morning solar irradiation goes from 0% night irradiation to 100% noon irradiation and temperature rises from morning to noon.
• In the evening solar irradiation goes from 100% noon radiation to 0% night radiation and temperature goes down from noon to evening.

How come the long term temperature slope as a function of solar irradiation can go up in reverse for weakening solar irradiation ?

• Climate is a linear low pass filter making temperature phase delay on the solar irradiation cycles ?
• Climate is a linear high pass filter making temperature phase advance on the solar irradiation cycles ?
• Climate is a linear band pass filter making temperature phase delay or advance on the solar irradiation cycles depending on the frequency of the cycles ?
• Climate is a non-linear filter ?

Based on "Deutsche Grundlichkeit" in Berlin they have an answer : The 90 year periodic Glassberg cycle and the other cycles interfere and over the past 3 centuries the cycles look like century cycles making +1°C-(-1°C)=2°C peak to peak temperature cycles.

So in Berlin temperature in 1800AD was about at the temperature now in Berlin with a cold minimum about 100 year ago.

So in Berlin they see a 200 year temperature cycle or about half of the frequency of the Glassberg solar cycle.

In Berlin climate, they have a "frequency divide by 2" installed on the Glassberg cycle ?

Cycles indeed ...

• But how come the Glassberg temperature cycle goes up after 1980 and the Glassburg solar irradiation cycle goes down after 1970 ?

Does atmospheric climate shift the phase of temperature cycles with phase delay or with a phase advance on the solar irradiation cycles ?

• For the day/night cycle at 365 thousand cycles per millennium periodicity, we see almost no phase delay/advance.
• For the 90 year Glassberg cycle we see a lot of phase shift between temperature and solar irradiation.
• But do we see phase delay or phase advance ?

Solar irradiation measurements and calculations started about 25x10,8year=270 year ago and we are now in solar cycle 25 counting in 10,8 year solar sunspot cycles.

On 1365W/m2, 3W/m2 or 0,22%=2197ppm difference in solar irradiation makes the difference between solar cooling and solar warming ?

No says the ACB="Anti Carbon Dioxide Brigade".

On 425ppmCO2-300ppmCO2, +125ppmCO2=0,0125% makes the difference between atmospheric cooling and atmospheric warming !

So : 99,9575% af the atmosphere gets warmed up by 0,0425% of the atmosphere.

That is if you allow the ACB to neglect water vapor in the atmosphere.

Water vapor humidity in atmosphere is indeed 10x higher than CO2=CarbonDioxide concentration near earth surface.

Over the past half century, the specific humidity anomaly went up 400ppm/50year=+0,2g/kg-(-0,2g/kg)/50year=+0,4g/kg/50year=8ppm/year

Over the past 60 year CO2 concentration went up 100ppm/60year=1,666ppm/year.

But : (+8ppmH2O/year)/(1,666ppmCO2/year)=5x

=>5x more H2O increase than CO2 increase per year.

Conclusion

• Water vapor concentration is 10x higher than CO2 concentration near earth surface
• Water vapor concentration is rising 5x faster the CO2 concentration near earth surface
• Water vapor is greenhouse gas number 1
• CO2 is greenhouse gas number 2

Is water vapor more important than CO2 as a greenhouse gas or less important ?

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 :
