///////////////////////
Global warming is orbitally forced, it doesn’t happen because of fossil fuels burning.
///////////////////////
We do planets and moons surface temperatures comparison.
The presence of atmosphere doesn't warm Earth's surface.
It is the other reasons, not the presence of atmosphere, that make Earth warmer than the Moon by +68°C.

Key words:
Specular Reflection
Φ - Solar Irradiation Accepting Factor (spherical shape and surface roughness coefficient), for smooth bodies Φ = 0,47 and for rough / porous Φ = 1

It is a demonstration of the Planet Surface Rotational Warming Phenomenon!
Very interesting !
Mars and Moon satellite measured mean surface temperatures comparison:
210 K and 220 K
Let's see what we have here:
Planet or.......Tsat.mean
moon............ measured
Mercury............340 K
Earth.................288 K
Moon................220 Κ
Mars.................210 K
Let’s compare then:
Moon:
Tsat.moon = 220K
Moon’s albedo is a.moon = 0,11
What is not reflected is (1 - a.moon) = (1- 0,11) = 0,89
Mars:
Tsat.mars = 210 K
Mars’ albedo is a.mars = 0,25
What is not reflected is (1 - a.mars) = (1 - 0,25) = 0,75
Mars /Moon satellite measured temperatures comparison:
Tsat.mars /Tsat.moon = 210 K /220 K = 0,9545
the Mars /Moon ratio of the incident solar irradiation the albedo determined not reflected portion (which relates in ¼ powers) comparison:
( 0,75 /0,89 )¹∕ ⁴ = ( 0,8427 )¹∕ ⁴ = 0,9581
Conclusions:
1. Mars /Moon satellite measured temperatures comparison
( 0,9545 ) is almost identical with the
the Mars /Moon ratio of the incident solar irradiation the albedo determined not reflected portion (which relates in ¼ powers) :
( 0,9581 )
2. If Mars and Moon had the same exactly albedo, their satellite measured mean surface temperatures would have been exactly the same.
And this is very interesting !
3. Mars and Moon have two major differences which equate each other:
The first major difference is the distance from the sun both Mars and Moon have.
Moon is at R = 1 AU distance from the sun and the solar flux on the top is So = 1.361 W/m² ( it is called the Solar constant).
Mars is at 1,524 AU distance from the sun and the solar flux on the top is S = So*(1/R²) = So*(1/1,524²) = So*1/2,32 .
(1/R²) = (1/1,524²) = 1/2,32
Mars has 2,32 times less solar irradiation intensity than Earth and Moon have.
Consequently the solar flux on the Mar’s top is 2,32 times weaker than that on the Moon.
The second major difference is the synodic rotation period both Mars and Moon have.
Moon performs 1 rotation every 29,531 earth days.
Mars performs 1 rotation every 24,622 hours or 0,9747 rot /day.
Consequently Mars rotates 29,531 *0,9747 = 28,783 times faster than Moon.
So Mars is irradiated 2,32 times weaker, but Mars rotates 28,783 times faster.
And… for the same albedo, Mars and Moon have the same satellite measured mean temperatures.
Let’s make simple calculations:
The rotation difference's fourth root is
(28,783)¹∕ ⁴ = 2,3162
And the irradiating /rotating comparison
2,32 /(28,783)¹∕ ⁴ = 2,32 /2,3162 = 1,001625
It differs only 0,1625%
It is obvious now, the Mars’ 28,783 times faster rotation equates the Moon’s 2,32 times higher solar irradiation.
That is why the 28,783 times faster rotating Mars has almost the same satellite measured mean surface temperature as the 2,32 times stronger solar irradiated Moon.
Thus we are coming here again to the same conclusion:
THE FASTER A PLANET ROTATES, THE HIGHER IS THE PLANETS MEAN SURFACE TEMPERATURE
If Moon and Mars were the same distance from the sun, the faster rotating Mars would have been a warmer planet.
Earth and Moon are at the same distance from the sun. The faster rotating Earth is warmer than Moon.
This very important conclusion is based on satellite measured planets mean surface temperatures. It is based on the very reliable observations.
Conclusion:
Everything is allright.
It is a demonstration of the Planet Surface Rotational Warming Phenomenon!
And it is the confirmation that the planet axial spin (rotations per day) "N" should be considered in the fourth root in the ( Tmean ) planet mean surface temperature equation:
Tmean.planet = [ Φ (1-a) So (1/R²) (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴.

The faster a planet rotates (n2>n1) the higher is the planet’s average (mean) temperature T↑mean:
Tmin↑→ T↑mean ← T↓max
