A rare true statement
about climate change
from the IPCC in 2007:
“ we should recognize
that we are dealing with
a coupled nonlinear
chaotic system,
and therefore that the
long-term prediction
of future climate states
is not possible. ”
CO2 levels in the atmosphere
were HIGHER than today,
for the first four billion years
of Earth’s history.
CO2 levels have been DECLINING
for the past 100 million years.
About 20,000 years ago,
CO2 got close to 150 ppm,
below which plants
begin to starve,
then stop growing.
CO2 below 150 ppm
would bring
the extinction
of most, maybe all,
terrestrial species
on our planet.
CO2 is essential
for life on Earth.
Society has been misled
by junk climate science
into believing that global CO2
and the average temperature
are too high, when the opposite
is true.
Earth has been
in a COOLING period
since the Eocene
Thermal Maximum
50 million years ago,
when the entire planet
was ice free.
Ancestors of every species
living on Earth today
survived through
what may have been
the WARMEST period
in the history of life.
Antarctica glaciers
began to form
30 million years ago,
and glaciers began to form
three million years ago
three million years ago
in the northern hemisphere
Today we are experiencing
one of the COLDEST climates
in Earth’s history.
We have learned
from Antarctic ice cores
that in the past 800,000 years
there have been major glaciations,
followed by warmer interglacials,
in 100,000 year-cycles.
These cycles coincide with
the Milankovitch cycles
( caused by eccentricity
of Earth’s orbit,
and its axial tilt,
which I like to call
"planetary geometry". )
Ice core studies show
the CO2 level
LAGS temperature
by an average of 800 years,
during the most recent
400,000-year period.
The Milankovitch cycles
cause a change
in temperature,
which then causes
a change in CO2,
( from outgassing of CO2
from the oceans
during warming periods,
and absorption of CO2
by the oceans
during cooling periods. )
20,000 years ago,
at the peak of the
last major glaciation,
Chicago and Detroit
were covered by
over a half mile of ice.
The sea level
at peak glaciation
was 120 meters lower
(about 400 feet lower)
than it is today.
By 7,000 years ago
all the low-altitude,
and mid-latitude glaciers
had melted.
There was
a 30-year period
of warming
from 1910-1940,
then a cooling period
from 1940 to 1975.
The warming
from 1975-2000,
is blamed on
man made CO2.
That's jumping
to a conclusion.
The very similar
1910-1940 warming
is NOT blamed on CO2.
All life on Earth is carbon-based.
CO2 is the most important
building block
for all life on Earth.
Therefore “carbon”
can NOT be a “pollutant”.
Plants, including trees
and all our food crops,
are capable of growing faster
with higher levels of CO2
than the 400 ppm today.
The optimum level
of CO2 for plant growth
is 1,000 to 2000 ppm,
based on thousands of
real scientific experiments,
not computer models.
We are witnessing the
“Greening of the Earth”
as higher levels of CO2,
due to human emissions
from burning fossil fuels,
cause increased plant growth
around the world.
This has been confirmed
by scientists with CSIRO
in Australia, Germany,
and North America.
Roughly half of the CO2
humans are emitting
from burning fossil fuels
remains in the atmosphere.
The other half
must be going
into an increase
of plant biomass.
Even today,
with 400 ppm CO2,
plant growth
is restricted,
and would be higher
if CO2 levels were
1,000 to 2,000 ppm.
More CO2 in the air
is good news !
