Short answer:
We don't need any more
wrong climate predictions.
The existing climate
models are a waste
of money -- usually
taxpayers' money.
And our mass media
should be ashamed
of themselves for evading
the subject of failed
climate model predictions:
Long answer:
There's no need to refute
the so-called climate models
-- they refute themselves,
by grossly over-predicting
global warming !
What are officially called
“General Circulation Models”,
are really elaborate versions
of the opinions of the people
who programmed them.
Personal opinions,
made very complex
with math and data.
None of those
personal opinions,
which are different
for each model,
add up to
a real model
of the climate
change process
on this planet.
A real model
would make
would make
right climate
predictions,
not wrong
predictions !
predictions,
not wrong
predictions !
There's one Russian model
that seems to make decent
predictions, apparently by
predicting future warming
from adding CO2 to the air
will be similar to the past
global warming while
CO2 was being added
to the air
( no one can be certain
if CO2 caused any
of the warming in the past
-- but it's a reasonable
assumption that increasing
CO2 caused some warming ).
I have to assume Russians
had carefully considered
the past 100+ years of adding
CO2 to the air, and the past
100+ years of mild, intermittent
global warming, when they
were constructing their
"more of the same"
climate model !
I'm not saying the Russians
know exactly what causes climate
change, and no one else does.
I am saying the Russians
present a model that appears
to be in the ballpark with
its predictions.
Every other nation
seems perfectly happy
to make the same wrong
forecasts year after year,
for over 30 years --
that should embarrass
real scientists.
Excluding the Russian model,
all the many other climate
models in the world,
on average, predict triple the
global warming that actually
happened in the past,
( based on UAH weather
satellite data starting in 1979 ).
We're talking about an actual
average of +0.1 degrees C.
warming per decade, versus
+0.3 degrees C. warming
per decade, based on the
average predictions of the
non-Russian climate models.
The models look even worse
if you start the analysis in 1940.
CO2 levels have been increasing
since 1940, so there is no logical
reason to start the analysis in 1979.
The temperature data before 1979
are only non-global surface data,
which includes lots of estimates
for areas with no thermometers.
The NASA-GISS compilation
( used for the chart on
this blog's home page ),
shows the global average
temperature in 1979
was about the same
as the temperature in 1940
( how often have you
seen that fact in the
mass media ? ).
Starting from 1940,
the total global warming
through 2018 was about
+0.5 degrees C.
( UAH satellite
data from 1979 )
which is an average
of only +0.065 degrees C.
per decade.
That's less than one quarter
of the global warming per decade
predicted for the future !
That's an
"it's different this time"
"it's different this time"
forecast, that's very likely
to be wrong, just like every
other long term climate forecast !
other long term climate forecast !
I prefer no predictions --
predictions of the future
climate have been
consistently wrong.
I would not object to
a "more of the same"
prediction, like the
Russian climate model.
That's a low risk prediction.
So, if I was forced
to make a climate
prediction, that's
what I'd say,
although I'd call it
the "null hypothesis",
to sound scientific !
Null hypothesis
is a very confusing
scientific term
that I learned
in the 1980s,
when doing
audio component
double blind tests.
It could even confuse
some audio engineers,
so I prefer saying
"more of the same".
After making
wrong predictions,
honest people
would go back
to the scientific
"drawing board"
and try again.
But not the
climate change
scaremongers.
Unfortunately,
only wrong climate
predictions
are possible,
or a lucky guess.
Because the physics
of climate change
is not known with
any precision,
so it is impossible
to construct a real
climate model, that
makes reasonably
accurate predictions.
… however
just enough
is known to play
"computer games",
and make consistently
wrong predictions,
that are stated with
great confidence.
The climate modelers
( computer gamers, actually )
merely assume
the CO2 level
is most important
for determining the
future global average
temperature,
and all natural causes
of climate change
just add up to “noise”.
Then they try to get
the public’s attention
by inventing a water vapor
positive feedback theory
that allegedly triples
the alleged warming
effect caused by CO2
alone.
The near global measurements
of the global warming rate
since 1979 ( UAH compilation )
would have to be tripled
to match the average
climate model prediction
of global warming
( excluding the Russian
model, that seems to predict
the past rate of warming
will continue ).
Anyone with common sense
would reject the water vapor
positive feedback theory,
because without that alleged
“global warming tripler”,
the average climate model
would seem to make
a reasonable prediction !
But the leftists in charge of the
“coming global warming crisis
boogeyman” DO NOT like to
change their predictions.
They love the old 1970’s-era
CO2 – temperature relationship
highlighted in the
1979 Charney Report
( +1.5 to +4.5 degrees C.
global warming per
+100% CO2 increase ).
And they have stuck
with that "formula"
- FOR 40 YEARS SO FAR -
and never mind
the always wrong
climate predictions
— the mainstream media
never reports them,
so few people know.
Every year we hear
a “new” prediction
of a coming climate
change crisis, and
every year the logical
people among us wonder
why it never arrives !
Of course the climate
computer games
have to be wrong, because
not enough is known about
climate change physics
to construct a real
climate model.
The computer games
make wrong predictions
— in real science
wrong predictions falsify
the climate theories
of the modelers.
But in climate alarmist
junk science, nothing
can be falsified !
WHY DO WE NEED
CLIMATE MODELS
WHEN WE HAVE
SO MUCH EXPERIENCE
WITH GLOBAL WARMING ?
We have over 300 years of
actual experience with
intermittent global warming
( since the late 1600s ).
We have over 100 years
of actual experience with
adding CO2 to the atmosphere.
We have decent near-global
temperature averages since 1979.
We have decent global average
CO2 measurements since 1958.
Why not assume the past
mild, intermittent global
warming trend will continue,
and then move on to solving
real problems in the world ?
I know that such a prediction
is really boring, and most
climate "scientists" would
lose their government jobs
if mild, harmless global
warming was in our future.
But it is not as boring as
the RIGHT PREDICTION.
The right prediction
is NO PREDICTION.
NO ONE KNOWS
whether the global average
temperature will be warmer,
or colder, in 100 years
… and we don’t even know
if the Holocene inter-glacial
( the current warm period
between ice ages, that we
live in ) will still be in progress !
What we do know is
the global warming
so far has been
harmless, at worst,
and beneficial, at best
( greening the planet and
supporting better growth
of C3 plants used for food
by people and animals ).
Why would anyone
in their right mind
want the 300+ years
of mild global warming
to stop ?
The climate history of our
planet strongly suggests
that when a global
warming trend stops,
a global cooling trend
will begin.
Most people would not
like global cooling,
with the exception
of ski bums.
People living in the
late 1600s hated the
unusually cold climate
back then.
