First, an abstract
for the impatient:
The often heard claim
of "climate science" that the earth would have a mean temperature
of 18°C without "natural greenhouse effect" is a proof
that these people obviously misinterpret reality!
If there would be
something verifiable at this model calculation, which just claims, without
a socalled natural greenhouse effect the earth average temperature would
be only at 18°C, there should not be measurable ground temperatures
up to approx. +80°C in deserts near the equator. And for this you
don't need a greenhouse effect, it is enough to reduce the solar constant
1368 W/m² by the albedo of about 30% and to roughly estimate the
possible maximum temperature with the StefanBoltzmann formula, which
calculated then results in about +87°C.
The observation of the reality proves clearly that the rotating irradiation
semicircle of the sun in the zenith draws a daily repeating heat trace
over the earth, which causes that the heat reservoir earth at the surface
charges up to those temperatures, which are directly measurable. Especially
the oceans, whose water temperatures remain de facto identical day and
night depending on the latitude, prove this. No point on earth follows
a theoretical temperature profile, which can be determined as the result
of a StefanBoltzmann calculation, based on a 24 hour period of the respective
local radiation power.
Therefore all considerations, which e.g. lead to the assumption, the irradiation
amounts exclusive Albedo in the average 239 W/m² and lead to the
assumption, the average temperature would be 18°C, are absurdities
of special class. If one takes this into account, this leads to which
consequence?
