That is a moronic assumption if N2 and O2 do not radiate
much in the infra-red.
Thats just they thing - N2 and O2 do radiate IR, everything on this
planet, save light bulbs and anything over about 5000K does radiate
IR. The frequency of radiation is dependant on temp
The last I heard the average temperature of the troposphere
was less than 300K.
Since half of all atmospheric radiation is upward, isn't
it obvious that without GHGs, the N2 and O2 atmosphere would
be much warmer.
Without GHG's they'd be colder.
How, if N2 and O2 don't radiate much IR?
Try to think things through instead of just accepting the
accepted ideas.
The more CO2 is there, the stronger the effect is.
Didn't you know that water vapor is many times the
GHG that CO2 is, and clouds radiate broadband in IR,
which radiates away all the latent heat carried upward
in evaporated surface water.
Mercury has no atmosphere - that's why its frozen - no greenhouse - no
oxygen - no ozone - no nothing.
I don't think it is "frozen".
Venus also has much more N2 than Earth, and the latest
images show weather on Venus something like that on Earth,
with very dense clouds that seem to play a big role in the
temperature extremes.
I think you should check this out - the only similarities between
erath and venus is that the both have atmosphere, both have volcanos,
both have ground to tread but that where it stops. Venus has an
atmosphere made predominately of sulpher dioxide due to large scale
volcanic activity - the atmosphere is covered in cloud and it wasn't
till they sent robots there that they realised it had lightning. But
that doesn't make it like earth.
I read Aviation Week, and it has the latest news about
such things, at least giving a clue what to search for.
