I hope we never have
a real global crisis
to deal with.
The fake climate change
crisis has caused
enough trouble.
The fake climate change
crisis -- which is
always "coming",
but never arrives --
has shown us that
smarmy leftists
can make people
hysterical about
the future climate,
by using nothing more
than wild guess
predictions of the
future climate,
that have been
consistently wrong
since the 1970s.
The official atmospheric
concentration of CO2,
measured at Mount
Mauna Loa in Hawaii,
goes back to 1958.
CO2 levels from
before 1958 are
very rough,
based only on
air bubbles in
Antarctica ice cores.
It's easy to measure
the air bubbles -- it's hard
to know exactly what
year they formed.
Surface temperature data
are far from being global,
especially before 1950.
There's lots of wild guessing
for areas with no thermometers,
and areas with missing data.
The wild guessing
is called "infilling",
but any guess,
with no data,
that can never
be verified,
is really
a wild guess.
Weather satellite
temperature data
are close to being global,
are measured in the
troposphere, where the
relevant greenhouse effect
occurs, and also measured
in a consistent environment.
The chart below shows
Mauna Loa CO2 (green)
and UAH satellite (red)
global average
temperature data:
The temperatures
fluctuates a lot,
but generally stay
within a 0.6 degrees C.
range, except for
two brief heat peaks
in 1998, and 2015 / 2016.
Those years included
large Pacific Ocean
heat releases
( aka "El Nino's" )
that are unrelated
to greenhouse gases
in the atmosphere
... yet are included
in the global warming
data blamed on CO2.
The trend of CO2
is much steeper than
the temperature trend.
But after about 2005,
the UAH temperature
trend line flattens out,
relative to the CO2
trend line.
That effect should
have been expected.
The greenhouse
gas theory is that
each increase
of the CO2 level,
let's say by +10%,
will cause less
global warming
than the prior
+10% increase.
Even climate alarmists
would agree with that.
What the alarmists do
to create a scary prediction,
is to claim that CO2-caused
global warming increases
the amount of water vapor
in the atmosphere, which
then triples the global
warming effect of CO2 alone.
There's no proof that
water vapor amplification
exists in real life.
If water vapor amplification
did exist in real life,
there would have been
runaway global warming
billions of years ago !
Because there was
much more CO2
in the atmosphere
for most of Earth's
4.5 billion years,
up to 10x higher
than the current
CO2 level, yet
there's no evidence
of runaway warming
in the past.
The CO2 no longer
in the atmosphere,
is sequestered
underground as
carbon in oil,
natural gas
and coal
-- burning those
fossil fuels
"recycles" carbon,
from underground,
back into the
atmosphere,
as CO2.
