Two primary energy flows
from Earth's surface
through the atmosphere
into space were speculated
in the influential
1979 Charney report:
(1)
Carbon dioxide (CO2) absorbing
and re-radiating (interfering with)
some of the outbound
long-wave infrared radiation
from the Earth's surface
to space, as Earth cools off.
This process is simulated
in infrared spectroscopy
in laboratories.
It is assumed that the same
effect happens in the troposphere,
and that is a reasonable assumption,
but the quantity of warming is not
known -- the lab experiments,
and actual warming since 1950,
strongly suggest mild, harmless
global warming, and
(2)
Increased water vapor
absorbing and re-radiating
(interfering with) even more
outbound long-wave infrared
radiation.
According to the
1979 Charney Report,
the increased water vapor
triples the effect of CO2 alone.
A1997 model of Earth’s
“Annual Global Mean
Energy Budget”
presented by the
Kiehl and Trenberth
paper published by
the American
Meteorological
Society.
In their graph, Figure 7,
one can see the component
allocated to outgoing
longwave radiation
and the component
allocated to
increasing water vapor,
evapotranspiration
and latent heat.
According to the UN
Intergovernmental Panel
on Climate Change (IPCC),
there's a water vapor
component of release
of latent heat
in the upper troposphere.
Energy from the sun
causes water vapor
and evapotranspiration
to rise in the atmosphere,
which condenses
into liquid water
(or ice) in the
upper troposphere,
giving off heat.
some of which
is radiated into space,
cooling our planet.
This is called
the “hot spot,”
assumed to be
over the tropics,
and strongest
at a pressure between
300 to 200 millibars (mb)
( which is roughly
9 to 11 km up, or
30,000 to 36,000 feet
above the tropics ).
This “hot spot”
has not been found
and is not increasing
as it should if the
water vapor component
of “CO2-caused
global warming”
is as strong as claimed
in the Charney Report,
and assumed by the IPCC
and others for 40 years.
The recent 2018
McKitrick and Christy paper
demonstrated that 60 years
of weather balloon data
have shown no such warming
is taking place.
Forty years of comprehensive
atmospheric temperature trends,
measured with weather satellites,
also failed to find any "hot spot".
As a result, the projections /
forecasts / predictions
( wrong wild guesses, actually! )
from climate models,
are for triple the warming
that has actually happened.
Without this "hot spot",
predictions of dangerous
greenhouse gas warming,
as described in
government-supported
publications,
is not occurring.
The warming process
is not intensifying
from a water vapor
positive feedback,
as asserted in the
1979 Charney Report,
assumed to be a fact
by the UN's IPCC.
and used by
climate modelers
to predict triple
the global warming,
that actually happens !
No "hot spot" means
global warming
is no worse than
mild and harmless,
which is exactly what
CO2 lab experiments,
and temperature
measurements, since 1979,
made from the troposphere,
had suggested all along.
In summary,
you get to choose
(A), or (B):
(A)
An unproven water vapor
positive feedback theory,
with zero evidence, or
(B)
Real science experiments,
done in laboratories,
somewhat confirmed
by actual temperature
observations, using
weather satellites and
weather balloons.
Only a fool would
believe (A),
and dismiss (B),
but that is
EXACTLY
what global warmunists do !
