The very POWERFUL the Solar Irradiated planet surface Rotational Warming Phenomenon: ( N*cp )1/16
We do the 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.

Venus' Without-Atmosphere Mean Surface Temperature calculation.
R = 0,723 AU, is the Venus’ distance from the sun in astronomical units
1/R² = 1,9130
Venus’ albedo: avenus = 0,76 Bond
Venus is a gases planet, Venus’ solar irradiation accepting factor Φvenus = 1
β = 150 days*gr*oC/rotation*cal – is the Rotating Planet Surface Solar Irradiation INTERACTING-Emitting Universal Law constant
1/243 rotations /per day, is the planet's Venus sidereal rotation spin.
On the Venus atmosphere winds are 60 times faster than the planet's Venus sidereal rotation spin. Since Venus has very thick atmosphere and being considered a gases planet, the Venus' rotation spin will be calculated as
N = 60* 1/243 = 60/243 = 0,24691 rotations per day
cp.venus = 0,19 cal/gr*oC, it is because the surface is regolith – dry soil
σ = 5,67*10⁻⁸ W/m²K⁴, the Stefan-Boltzmann constant So = 1.362 W/m² (So is the Solar constant)
Venus’ Without-Atmosphere Mean Surface Temperature Equation Tmean.venus is:
.
Tmean.venus = [ Φ (1-a) So (1/R²) (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴
Τmean.venus = [ 1(1-0,76)1.362 W/m² 1,9130*(150 days*gr*oC/rotation*cal *0,24691rotations/day*0,19 cal/gr*oC)¹∕ ⁴ /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =
Τmean.venus = [ 0,24*1.362 W/m²1,9130*(150*0,24691*0,19)¹∕ ⁴ /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =
= [ 0,24*1.362 W/m²1,9130*(1,6287) /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =
Τmean.venus = ( 4.490.620.150,82 )¹∕ ⁴ =
Tmean.venus = 258,87 K
And we compare it with the
Tsat.mean.venus = 735 K, measured by satellites.
What we see here is that planet Venus has a strong greenhouse warming effect due to the greenhouse gas CO2 96,5 % high content in the Venus' atmosphere.
Venus' Without-Atmosphere Mean Surface Temperature calculation.
Venus' atmosphere composition:
96,5 % CO2 carbon dioxide is a greenhouse gas
3,5 % N2
and
at ground level Venus' atmospheric density is
D = 65 kg/m³.
Venus' atmosphere has 280.000 (two hundred eighty thousands) times more CO2 molecules on the ground level than Earth's atmosphere has.
Whatever influence the CO2 on the surface temperature, it is 280.000 times less on the Earth's surface compared to Venus' surface.
