The so-called "models"
over predict the rate
of global warming
by two to three times.
So they are failed models.
Yet smarmy modelers
kept using their
computer games,
and kept making
the same scary
"coming climate crisis"
predictions, every year,
for over 30 years.
Always consistent,
but always wrong,
There are no real
climate models, that
make accurate predictions,
because climate change
physics is still a mystery.
A real model requires
a thorough understanding
of climate change physics.
The half degree C.
of global warming
since 1979, measured
by weather satellites,
could have had 100%
natural causes,
or 100% man made
greenhouse gas causes,
or some combination
of the two causes.
No one knows the "truth".
Climate "models"
play a big role
in the attribution
of global warming
to human causes.
But the "finding"
that humans
are the cause of global
warming, was the main
assumption used
to program
climate "models".
Circular reasoning --
the so called models
conclude what they
were programmed
to conclude.
The IPCC's
politicized
Summary for
Policymakers
is the latest
assessment
report (AR5)
The IPCC claims
there are eleven
"main drivers
of climate change”.
The IPCC guesses
how much each driver
has done since 1750,
which they call
a “forcing.”
The so-called climate
models assume any
observed climate
changes, over
that long period,
must be due to
11 drivers.
But 10 of the 11 drivers
are from human causes.
The only natural
cause driver
is changes
in solar input
( called “solar irradiance” ),
considered to be
so tiny, that it
can be ignored.
The IPCC merely assumes
all the drivers of climate
change are human caused.
And, if all the drivers
of climate change
are assumed to be
human caused, then
all the observed climate
changes must also
be human caused.
Here's what the IPCC
claims to "know":
(1)
An observed
global average
temperature change,
based on non-global
surface measurements,
with questionable
accuracy, especially
before 1920.
(2)
What the "model output"
looks like without human forcing.
(3)
What the "model" output
looks like with human forcing.
With only 1 tiny natural cause
of climate change, out of 11 causes,
it's no surprise that a "model"
can only show warming when
human causes are included.
The 18 "model" outputs
can not change over time
without human forcing,
because only one
tiny natural driver
is allowed.
The fix is in:
"Model" results
must match
initial assumptions.
And the IPCC claims
"models" prove
humans are the
sole cause of
climate change.
Anyone who
believes this
circular reasoning
is a gullible fool.
This modeling is
just junk science,
because the so-called
models are programmed
to reach the desired
conclusion.
There is no such thing
as science by assumption,
or belief.
