Back testing the climate models -- wrong "predictions" of the past too !

Climate change 
should be a subject 
that few people
care about.

The climate has 
barely changed
in the past 138 years
since 1880.

With "climate" 
being defined as
the average 
surface temperature
of our planet.

If you've lived 
in the same place
for a long time, 
your own 
observations 
of the weather,
over decades, 
will tell you 
everything 
YOU need to know,
about YOUR 
own climate.

After all, no one actually lives
in the "average climate" !

I've lived in the same home
in Bingham Farms, Michigan,
since 1987. 

Before that we
lived almost exactly
four miles south, 
in Southfield, 
Michigan, 
for seven years

That's a total of
38 years living
in the same area.

We only wish 
we had noticed
global warming
here in Michigan !

This winter has been
cold, especially 
November 2018.

The last two weeks 
of December 2017,
and the first week 
of January 2018, 
were the coldest 
three consecutive
weeks since 
I moved to Michigan,
from New York, 
in 1977.

I trust my own senses 
far more than 
government bureaucrats
telling me what 
the "average 
temperature" 
of our planet is.

Especially because 
a majority of 
our planet's surface 
has no thermometers,
or has missing data, which
government bureaucrats must
wild guess ( "infill" ) before 
they can compile a global 
average temperature !

Their wild guesses ALWAYS
result in more global warming 
than alternate methodologies
used to measure the temperature: 
weather satellites and 
weather balloons !

Of course they ignore
weather satellites and
weather balloons !

But never mind 
the very obvious
pro-global warming 
bias.

The "CO2 is evil cult" 
doesn't care about 
the past climate, 
whether the official 
surface measurements, 
or your own observations 
-- they only care about 
the future climate, 
as if they had any idea 
what the future climate 
will be.

Why is the 
future climate 
so important ?

Because anyone can claim
they "know" the future climate,
and no one can prove them wrong,
without waiting, and observing
the climate, for many decades !

For over 55 years 
the "warmunists"
have been warning 
about a coming climate
change disaster 
-- sometimes it was
a global cooling disaster, 
but mainly warning of
a global warming disaster.

How many decades have to pass
before people realize predictions
of the future climate are always wrong,
because no one knows what causes
climate change?

If scientists knew what causes
climate change, their predictions
would be correct -- in reality climate
predictions are consistently wrong ! 

Their computer 
climate models
make wrong 
predictions of the
future climate.

They also make 
wrong "forecasts"
when back-tested 
using the
past climate !



Here's the full story:


The average temperature
of our planet is claimed
to have increased only
+1 degree C. in the past 
138 years, with an honest 
margin of error of at least
+/- 1 degree C.

So what?

Has climate change been 
accelerating?

No.

In fact, the average temperature
has barely changed since 2003,
according to the most accurate
climate data available, 
from weather satellites.

Weather satellites 
were launched
in 1979, which was 
just a few years after 
the 1975 to 2003
warming period began.


They tell us the 
average temperature
in December 2018 
was only 
+0.25 degrees C.
warmer than 
the 1981 to 2010 
average temperature.

That minor climate change
would not even be noticed, 
if not for hysterical leftists 
bellowing about a coming 
climate disaster
( that never shows up ! ).




Government 
bureaucrats,
'sell' the simple, 
but false, myth, 
that carbon dioxide 
'controls the climate'.


They have science degrees, 
but their 'CO2 is evil cult' 
is based only on
wild guesses about the 
future climate, 
supported by very little
real science.

I have a science degree
 -- a BS degree -- 
but I didn't need 
a BS degree 
to realize that
predictions of 
the future climate 
were "BS", 
starting back in 1997,
about one hour after
I began reading 
climate science,
as a new hobby !

Lab experiments 
do suggest that
CO2 should have 
a mild greenhouse
effect in the 
atmosphere,
and a warmer 
atmosphere
should warm 
the surface
of our planet.

How much warming,
no one knows !

The experiments 
suggest up to 
+1 degree C. 
of global warming, 
from a doubling 
of the CO2 level, 
over the next 
100 to 200 years.

That's a mild 
and harmless 
rate of 
global warming.

At the current CO2
growth rate 
of 2ppm per year, 
assuming CO2 alone 
controlled the 
average temperature,
it would take 200 years 
for the average temperature 
of our planet to rise a mere 
+1 degrees C.

And that's a worst case estimate !





There's no 
scientific proof 
that CO2 
caused any 
of the mild 
global warming 
since 1940.

We've actually had 
significant global warming 
for the past 20,000 years,
with sea level rising 400 feet
from melting glaciers.

That global warming 
was NOT caused by
man made CO2, 
for at least the first
19,850 years, of the 
20,000 years !

The temperature record 
since 1850 shows nothing 
unusual -- the cause(s) of 
global warming since 1850
could have been natural,
unrelated to CO2.

Our planet has had
4.5 billion years of 
natural climate change,
with no evidence 
it stopped in the 
last century !

There's no proof 
man made CO2
suddenly became the 
'climate controller' 
in the last century,
and natural climate
change stopped ! 

But that's exactly what
we are told by the 
CO2 is evil cult !




The "climate business",
is controlled by many
government bureaucrats
with science degrees.


Those "scientists" 
MUST believe 
man made CO2 
controls the climate, 
or they won't be hired !

So they 'believe' what
they are paid to believe.




The government 
bureaucrats
must also believe 
a doubling 
of the CO2 level
will cause 
+3 degrees C.
of global warming.

That +3 degrees C. was a wild
guess, from the 1970s, and
it has never been revised.

It has also never happened !

The average computer 
climate model 
happens to predict
about +3 degrees C. 
of global warming 
per CO2 level doubling.

And even if you 
arbitrarily decided 
to assume ALL
global warming 
was caused
ONLY by CO2,
with no scientific 
proof of that, 
the "+3 degrees C. 
warming rate",  
of the average 
climate model,
is TRIPLE
the actual rate
of warming 
since 1950 !


In real science, 
the climate models 
would be dismissed
as worthless.

But not in 
modern 
"goobermint
climate
science", 
where wrong 
predictions 
don't matter
-- they are
just repeated
year after year,
since the 1970s
... which is 
a symptom 
of junk science !





Climate models 
are "tuned" 
to extrapolate 
the 1975 to 2003 
warming rate 
into the future, 
so they'd 
look great 
if back tested 
for that 1975
to 2003 period.

But models can 
only be verified 
( validated, or invalidated )
using time periods 
OUTSIDE of the period 
they were "tuned" to.

The flat temperature trend 
in the 15 years since 2003
is one such period.

Not one climate model 
predicted the flat trend
that actually happened !

The 1916 to 1945 warming 
is another such period.

Note: 
A multi-climate model average
is used to represent the 
consensus of scientists
who developed models.

The climate models look 
even more ridiculous
when you look 
at them separately,
rather than as 
an average model  !

(1)
Huge differences 
between 
measured 
and modeled 
global average 
surface warming, 
for the past 15 years,
since 2003, tell us 
the CO2 is evil cult 
really has no idea 
about what causes 
global surface 
temperatures
to change !



(2)
Back testing 
climate models 
reflects poor 
"hind-casting" too,
( "predicting"
global warming 
of only ONE THIRD 
of the actual warming 
from 1916 to 1945 ! )
( more details follow )


The computer 
climate models 
make no sense 
when forecasting,
or hind-casting 
-- they make very
wrong "predictions"
in either direction !




For the NASA - GISS 
( Goddard Institute for Space Studies )
Land-Ocean 
Temperature Index (LOTI), 
the 30-year period 
ending with 1945 
has the highest 
30-year warming rate 
before 1950.

LOTI data claim 
surface temperatures
warmed at a rate of
+0.15 degree C. 
per decade
from 1916 to 1945.

Note:
"Global" temperatures
include little data from the
Southern Hemisphere
before World War II, 
so are actually 
not really "global". 

For example, there were
very few measurements 
for Antarctica before the 
early 1950s.

Climate model 
back testing
"predicted" 
global warming 
of only 
+0.05 degrees C. 
per decade,
from 1916 to1945,
which was 
only ONE THIRD 
of the actual 
measured 
warming.

The computer models 
assume man made 
greenhouse gases
control the global
average temperature.

That assumption 
fails to explain the
1916 to 1945 warming
( greenhouse gases
could explain 
up to one-third 
of the total warming ).

Which means 
at least 
two-thirds 
of the warming,
from 1916 to 1945,
had natural causes,
unrelated to 
greenhouse gases.

And if at least 
two-thirds 
of that warming 
period was from 
natural causes,
then why can't 
at least two-thirds 
of the warming, 
from 1975 to 2003, 
also be explained 
by natural causes?




The climate model 
back testing outputs 
used here are those 
stored in the 
Coupled Model
Inter-comparison 
Project Phase 5 (CMIP5) 
archives, used by the 
United Nations’ 
Intergovernmental Panel 
on Climate Change (IPCC), 
for their 5th Assessment 
Report (AR5). 




The always wrong 
climate models'
global average
surface temperature
predictions are 
the primary metric 
of man made 
global warming.

They "predicted"
ONE THIRD the
actual warming
from 1916 to 1945,
when back tested,
and TRIPLE the 
actual warming
since the 1970s !

It's very obvious, 
from their very
wrong predictions,
that climate models,
as a group, 
are junk science !

The "CO2 is evil cult",
falsely claims 
man made CO2 
is very dangerous, 
and bases that claim 
almost entirely 
on junk science !

How can an 
"existential threat"
be based only on 
wrong wild guesses 
of the future climate, 
made by 
bureaucrats playing 
computer games,
that have no ability 
to predict the 
future climate ?




Only leftists 
would fabricate 
a 'climate change
is dangerous' scam,
based almost entirely
on junk science !

They are very emotional,
people, susceptible to
junk science, which is 
designed to stir emotions, 
with scary tales of a 
future climate disaster.

You'd think 
the scaremongering
would stop 'working' 
after over 50 years
of wrong predictions,
not to mention
the long forgotten, 
equally false scares,
about DDT, acid rain,
the hole in 
the ozone layer,
and global cooling.




Please don't be fooled 
by the climate change
scaremongering !

Past climate change
has been all good news,
starting with Chicago and
Detroit under glaciers,
20,000 years ago !

Leftists want you 
to completely ignore
the past climate.

Look only to the future,
they say, as if they knew
the future climate !

Leftists falsely claim 
the future climate 
will be different
-- only bad news
in the future.

Only gullible people 
would continue 
to believe 
the global warming
scaremongering,
after over 50 years 
of wrong predictions !

Especially after the flat
average temperature trend 
from 2003 through 2018,
that no model predicted,
demonstrating that 
actual global warming 
has practically stopped !




Past climate change 
is a fact, studied by
real climate scientists.

That's real science !



The future climate 
is unknown,
yet many liars
get attention,
government grants,
and government jobs,
by claiming they know 
the future climate.


That's junk science !
