The "global warmunists" spend
nearly 100% of their time
predicting a coming
climate change catastrophe
... that never comes.
We've been waiting
since the 1960's !
Same wrong predictions
made every year.
Government bureaucrats
have used the same
"CO2 formula"
since the 1970s.
When plugged into climate models,
it predicts triple the warming
that actually happens.
Yet the formula never changes.
Apparently a scary prediction
is much more important than
a correct prediction !
Scary warming has been
predicted for every decade.
What actually happened
was mild, harmless warming
in some decades, but not others.
And since 2003,
per weather satellite data,
global warming
was so small
that it's within
the +/- 0.1 degree C.
margin of error
in the measurements !
Let's forget about
the wrong wild guess
predictions of the
future climate for now,
and consider the Earth's
climate history:
Global temperatures have been
in a major cooling period since
the Eocene Thermal Maximum,
50 million years ago.
The Earth was an average of
+16 degrees C. warmer then !
The entire planet was ice free.
The Arctic and Antarctica
were ice-free, covered in forest.
The ancestors of every species
on Earth today survived through
what may have been
the warmest period
in the history of life
on this planet.
Glaciers began to form
in Antarctica 30 million years ago
and in the Northern Hemisphere
three million years ago.
Today we are living in the
Holocene interglacial
( interglacials are warm periods )
of the Pleistocene Ice Age,
yet our current climate
is one of the coldest climates
in Earth’s history.
From Antarctica ice cores,
used to study the climate in
the past 800,000 years:
There were cycles
including long-lasting
major glaciations,
followed by short, warm
interglacial periods,
in 100,000 year-cycles.
They coincide with
the Milankovitch cycles,
linked to the eccentricity
of the Earth’s orbit.
There's a strong correlation
between temperature
and atmospheric CO2
during these glaciations.
But CO2 peaks and troughs
LAGGED temperature,
by an average of 800 years,
during the past 400,000 years.
Ice core climate proxies show
temperature is the cause,
and CO2 levels are the effect.
Yet climate alarmists
ignore ice cores, except
to use them for CO2 levels
before 1959 -- they insist
that CO2 is causing
the temperature change,
despite no evidence of that
in climate history.
The peak of the
last major glaciation
was 20,000 years ago.
There were two miles
( 3.3 kilometers thick )
of ice on top of what is now
the city of Montreal.
95% of Canada was covered
by a sheet of ice.
Chicago and Detroit were covered
by up to a mile of ice.
The Milankovitch cycle says
this will happen again, gradually,
during the next 80,000 years.
At the peak of the last glaciation,
the average sea level was about
400 feet ( 120 meters ) lower
than it is today.
By 7,000 years ago,
all the low-altitude,
mid-latitude, glaciers
had melted.
During the Holocene
Thermal optimum,
from 9,000 to 5,000 years ago
the Sahara "desert" was green !
Since 1700:
Temperature has risen
at a slow, steady rate
in Central England since 1700,
while CO2 emissions
were not relevant until 1850.
The later exponential rise
of CO2 levels was after 1950.
After freezing over regularly
during the Little Ice Age,
the River Thames froze
for the last time in 1814,
as the Earth moved into
the Modern Warm Period.
The IPCC states it is
“extremely likely”
that human emissions
have been
the dominant cause
of global warming
“since the
mid-20th century” (1950).
They claim that
“extremely” means
95% certain,
even though
the number "95"
was plucked from the air,
and has no scientific meaning.
“Likely” is also
not a scientific word
-- it's just an opinion.
Average temperatures,
and CO2 levels,
did not correlate
during many decades
after 1900:
There was global warming
from 1910 to 1940,
cooling from 1940 to 1975,
warming from 1975 to 2003,
and a flat trend after 2003.
Warmists claim
higher CO2 will levels
will result in
a positive feedback
from more water vapor
in the air,
magnifying the effect
of CO2 alone,
by three times.
And that's what
the average computer
climate model predicts.
... But the average model
predicts triple the warming
that actually happens !
Which is strong evidence the
water vapor positive feedback
is pure baloney !
This 2007 statement
about climate change
was one of the few times
the UN's IPCC was honest
with the general public:
“We should recognize
that we are dealing with
a coupled, nonlinear
chaotic (climate) system,
and therefore the
long-term prediction
of future climate states
is not possible.”
But the IPCC
does not listen
to their own advice:
We are still getting
the scary, wrong,
computer game
climate predictions
every year,
for the past
three decades !
