This discussion isn't for you because I
don't think you or the true warmies would
ever allow any logic or reason to change
your thinking, it is made in the hope that
there will be people that are able to think
and maybe it will result in more ideas.
Water is the game changer, while water
becomes the most plentiful GreenHouse
Gas, and absorbs the most IR from both
the Sun and the solid and liquid surface
of Earth, it also prevents the surface from
getting anywhere near as hot in daytime.
Without water and water clouds, the
surface of Earth would get as hot or
hotter than the moon, the only reasons
it might not get quite as hot is the heat
from the molten core of Earth, and the
difference in the length of daylight and
darkness.
The surface of Earth would also get
colder at night than it does now, but
may not get as cold as the moon, as
the length of the day/night periods are
not as long.

"As you may have learned, the moon doesn't have any air around it. The
air that surrounds our earth acts as a nice blanket to keep us warm and
comfy! But the moon, since it doesn't have this blanket, gets much
colder than the earth and much hotter than the earth."
Note that the above states it is the
air that keeps the Earth warmer than
the moon, is there a reason it does
not say it is the GreenHouse Gases
that keep the Earth warmer?

And obviously, the Earth doesn't
get as hot as the moon, because of
water, and the water clouds shielding
the sun over part of the Earth.
The polar regions on Earth would
be different than on the moon, maybe
getting even colder than the moon
gets in darkness, but nowhere near
as cold in the six months of daylight.
The important thing is that, without
water and GHGs, the surface of Earth
in daylight would reach over 200 degrees
F, and the air in contact with the hot
surface would bounce away violently,
transferring part of that energy to the
other molecules of N2 and O2 that
it comes in contact with.
There is some question here about
what temperature is, and how it is
transferred, but speed of molecular
motion is a big part of temperature,
and it will take more thinking to be
able to decide just how hot the air
composed of only N2 and O2 would
get in the absence of water and GHGs.
Is there any doubt the N2 and O2
air would get hotter than it gets now
without water, water clouds, and the
GHGs? I don't think so.
And without the GHGs, the air
of only N2 and O2 molecules would
have no way to cool except by some
contact with the surface after the
surface cools in darkness.
That cooling would not reach
anywhere near the rate of energy
transfer as the warming in daylight
because the molecules of air would
not bounce with as much speed,
and would not absorb as much of
any other aspect of temperature
as it does in being heated.
I have to assume that the air
of only N2 and O2, without water
and water clouds would get hotter
than now, and without GHGs
would have almost no cooling
at all.
A guess can be made about
what the temperature of the air
without GHGs would stabilize at,
but it would be nearer the hottest
temperature the surface reaches
in daytime than the average
temperature.
The surface would get a lot
hotter and a lot colder without
GHGs and water and water
clouds, but the air would not
have the cooling ability, and
would assume a stable warmer
temperature than now.
The flaw that I see is in the
thought that it is GHGs that
absorb the heat, without the
consideration that it is water
that prevents the extreme
increase in temperature in
daytime.
The GHGs, by both absorbing
and radiating IR, moderate the
temperature of the atmosphere,
but cool it more than the GHGs
warm it.
The cooling by IR radiation
to space exceeds the warming
by absorption from all radiation,
because the atmosphere is
warmed by contact with the
surface, and by UV interactions.
There is a good chance that
no real study of what the Earth's
temperature would be without
water has ever been made, too
much of science is based on
prior published ideas and not
as informed assumptions.
Water is the defining gas
and liquid, in both warming
and cooling, no assumption
can be made about temperature
without considering the role
of water.
That is probably how the
flaw in climate science arose,
by only considering the IR
radiation, and not the other
aspects of what water does.
