Why the IPCC climate models are wrong -- predicting an average of triple the warming that actually happened in the past 30 years !

Note:
This article excludes one 
Russian climate model 
that does not over-predict
global warming, obviously
working in collusion 
with Donald Trump, 
so it can't be trusted !


Claims of dangerous 
greenhouse gas-caused 
global warming, 
are based on 
meaningless 
computer games -- 
-- "climate models"
that have made 
very wrong predictions
of the average temperature,
for three decades.

In real science, 
the 'IPCC climate models' 
would be falsified by 
their far off the mark 
average temperature
predictions.

But in modern 
climate "science",
it seems nothing
that is claimed 
can ever be falsified,
just like religious beliefs.

So, never mind 
the wrong predictions
for three decades, 
the IPCC will stick with
their wild guess number 
for how much 
global warming 
is caused by CO2,
that was first publicized
in the 1979 Charney Report,
... and never changed.

That number matches
the results of almost all 
of the climate models,
which are obviously 
programmed to get 
that "preferred",
but wrong, answer 
= a doubling of CO2 
in the atmosphere
will increase the
average temperature
by about +3 degrees C.

But, in reality, 
if we assume that
all the warming
since 1950 
was caused by CO2
( with no scientific proof 
that ANY of the warming 
was caused by CO2 )  
the warming rate 
has only been ...
... +1 degree C. 
per CO2 doubling,

... not +3 degrees C.
per CO2 doubling,

...so its no surprise
the climate model 
predictions 
have averaged 
triple the warming
that actually happened ! 


















The IPCC treatment 
of water vapor, 
is as a feedback 
that triples the warming 
allegedly caused 
by carbon dioxide alone. 

There is no evidence
that theory is correct.

But water vapor 
is the dominant 
greenhouse gas 
-- water vapor and clouds 
account for up to 90% 
of the greenhouse gas 
effect. 

Water vapor is natural, 
and constantly changing, 
both regionally 
and seasonally. 

Water vapor 
is a natural cause 
of greenhouse gas 
warming 
not a "feedback".



Naturally occurring 
water vapor 
also reduces the 
greenhouse warming 
potential of other gases, 
especially methane 
and nitrous oxide.



With greenhouse gases, 
the actual 
greenhouse effect 
is a slowing 
of Earth's cooling
( cooling by 
infrared heat from 
Earth's surface 
radiating upwards
toward space ... 
but the cooling rate 
is disrupted by
greenhouse gases).


CO2 mainly affects 
surface temperatures 
at night, although 
the reason for that
is still being debated***
( nights not 
cooling off
as much as they 
otherwise would,
before dawn,
is described as 
"global warming",
which misleads 
many people
about what is
really happening ).


*** The strongest reason,
in my opinion, at the link below,
why the greenhouse 
gas warming 
of surface temperatures,
is measured mainly at night:

The ‘greenhouse effect’ 
is attributed to gases 
that absorb and re-emit 
up going infrared energy,
in the 3 to 70-micron 
wavelength range,
where greenhouse 
gases have some effect.

But the cooling Earth 
emits very little 
infrared energy 
in the wavelengths 
that both methane CH4 
and nitrous oxide N2O 
can absorb.

The final cooling step, 
heat emission into space,
is infrared radiation 
leaving the 
upper troposphere 
and stratosphere.




The solar radiation 
coming down from the sun, 
is in the ultraviolet
and visible light wavelengths.

Clouds and water vapor
block some of the 
incoming solar energy. 

Greenhouse gases of
CO2 ( carbon dioxide ), 
CH4 ( methane ), and 
N2O ( nitrous oxide ), 
have almost no effect 
on incoming sunlight.






By ignoring 
water vapor 
as the primary 
greenhouse gas, 
the IPCC ignores 
the practical fact 
that water vapor 
severely limits 
the ability of methane (CH4)
and nitrous oxide (N2O)
to absorb outgoing radiation
as Earth cools,
severely limiting their 
greenhouse gas effect. 

The greenhouse effect
of both CH4 and N2O, 
are vastly overstated 
by the IPCC, 




The logarithmic relationship 
between atmospheric 
carbon dioxide (CO2)
concentrations and
average temperatures 
is based on the MODTRAN 
atmospheric model 
at the University of Chicago. 

Even with CO2 at the low
pre-industrial level 
( under 300 ppmv, 
or parts per million, by volume ) 
the influence of adding CO2 
to the atmosphere,
was already small.

And even smaller effect
starting at today's
CO2 atmospheric level 
of about 400 ppmv.


CO2 accounts 
for no more than 
10% to 20% of all
greenhouse warming,
and probably a lot less,
with water vapor 
and clouds
accounting for 
at least 80% to 90%, 
and probably a lot more.

The effects of 
CH4 and N2O 
are trivial. 




Reliable models 
for the effects of 
greenhouse gases 
can not exist
without a 
reliable model 
for the effects 
of water vapor,
which does not exist.




Earth's CO2 levels 
had been 
much higher than now, 
in most of the past 
4.5 billion years. 

There were no
climate "tipping points",
with runaway warming,
ending life on our planet.

There was no known
ocean acidification problem.

We know that because
corals flourished, 
leaving extensive 
fossil reefs 
for us to study.

The bad news back then
was giant meteor strikes, 
and massive 
volcanic eruptions 
that probably released 
carbon dioxide CO2, 
methane CH4,
nitrous oxide SO2, 
and other gases, 
that affected the oceans 
and atmosphere.

But evolution continued.




The only undisputed effect 
of adding CO2 to the air
over the past century, 
has been a 'greening' 
of the Earth.

And, of course,
that's good news !




Unfortunately,
modern climate "science"
consists of lots of 
government bureaucrats,
with science degrees, 
stating with great confidence,
for three decades so far, that
"we know the future climate", 
even as their very wrong
computer game predictions
prove they have no idea
what the future climate will be !

However, 
the bureaucrats 
know they will have 
permanent job security, 
to play computer games 
for a living,
as long as 
the politicians 
who hired them,
continue to claim 
a climate disaster 
is coming.



And that's why 
modern 
climate "science"
is junk science ... 
with the annual, scary, 
wrong climate predictions,
repeated year after year ... 
followed by the false claim
from leftist politicians,
that only a 
powerful government 
( which they've always wanted )
'can save the Earth 
for the children' !


It's self-serving 
junk science,
for money and power.
