The real “flat Earthers”
are climate modelers.
They still simulate
a flat world, due to
their limited
computing power.
And they have not yet
been able to predict
actual global warming.
German climate scientist
Dr. Sebastian Lüning's
comments on this subject
(in German) were at the
Die kalte Sonne website.
Dr Lüning cites a recently
published paper by
Prather and Hsu,
who claim that climate
models assume the earth
to be flat, which results
in major inaccuracies
in their results.
“The real flat-earthers
are the climate modelers,”
Lüning says.
Did you know that
all climate models
assume a flat earth?
A study by Michael Prather
and Juno Hsu in PNAS
explains that this
simplification causes
powerful distortions
in computer simulations.
Sunlight drives the Earth’s
weather, climate, chemistry,
and biosphere.
An assumption
in climate models is
a flat Earth atmosphere.
Spherical atmospheres
intercept 2.5 W⋅m−2
more sunlight, heating
the climate by an additional
1.5 W⋅m−2 globally.
With a
flat atmosphere
assumption,
regional heating
prediction errors,
particularly at
high latitudes,
have been huge.
Unlike flat atmospheres,
the constituents in a
spherical atmosphere,
such as clouds
and aerosols,
alter the total amount
of solar energy
received by the Earth.
To calculate
the net cooling
of aerosols
blocking sunlight,
in a spherical
framework,
one must count
the increases
in both incident and
reflected sunlight.
That reduces
the aerosol
sun blocking effect
by 10% to 14%,
relative to using
just the increase
in reflected sunlight.
But why correct
the climate models ?
They grossly
over predict
global warming,
and have done so
for over 30 years,
yet no government
bureaucrat scientist
seems to care.
The mainstream press
reports every scary climate
prediction, but not the fact
they are 100% wrong.
Early climate and weather
models were constrained
by computing resources.
The radiative transfer
of sunlight through
the atmosphere,
has always been
a costly component.
As computational ability
expanded, these models
added more resolution,
becoming the Earth system
models that we use today.
While many of the original
approximations have since
been improved, one of them
— that the Earth’s surface
and atmosphere are locally flat
—remains in current models.
Correcting from
a flat to spherical
atmospheres would lead
to regionally differential
solar heating predictions
-- and the new
regional predictions
could not be any worse
than the past regional
climate predictions
have been!
A spherical atmosphere
assumption would change
how we evaluate aerosol
direct radiative forcing.
The authors of the study
claim the resulting
climate model errors
are in the order of magnitude
of the total greenhouse gas
effects ( aka "forcing" ) !
Meaning solar
irradiation and
aerosol forcing
are falsified by
climate models.
