global warming
means anything bad -
the average temperature
of our planet
has already increased
at least 2 degrees C.
from the 1690s to 2018,
and anecdotal evidence
from the late 1600s
strongly shows
people HATED
the cold weather
-- so the warming
since then
was GOOD news !
We all agree that
climate changes.
We all agree,
the world has become
slightly warmer
in the past 120 years.
We all agree,
the observed increase
in CO2 concentration
in the atmosphere
is due to human activity:
such as burning fossil fuels
and other industrial activity.
Based on simple lab experiments,
adding CO2 to the atmosphere
should cause some amount
of global warming,
but how much is unknown.
but how much is unknown.
We all agree
the CO2 concentration
in our atmosphere
is increasing
about 2 ppm/year,
which is about half
of human emissions.
The other half
of human emissions
is absorbed
by the ocean
and biosphere.
We don't agree
on this real science:
If fossil fuels
on this real science:
If fossil fuels
are burned responsibly
to limit real pollutants
such as ash,
oxides of nitrogen,
oxides of sulfur,
heavy metals, etc.,
the CO2 released
benefits the world.
Any resulting climate change
will be small, and harmless
but there will be major benefits
to plant life.
Scientific truth has never been
determined by a vote,
or consensus,
In fact, consensuses
have often been
completely wrong.
Winter is warming
more than summer
and nights more than days,
which does suggest
greenhouse gas warming
rather than warming
from solar energy variations

Atmospheric CO2 levels today
are much lower than
during almost any time
in the history of life on Earth.
CO2 concentrations have been
much higher than today
over most of the history of life
on our planet.
There were ice ages
in the Ordovician,
450 million years ago,
when the CO2 levels were
several thousand ppm.
The weak case
that CO2 is the
dominant influence
on the climate
is based on
excessive faith in
computer climate models.
Models blur the lines between
reality and virtual reality.
All claims of dangerous warming
from greenhouse gases
come from computer models.
Over the past
550 million years,
when abundant fossils
first appeared
in the sedimentary record,
CO2 levels have averaged
many thousands of
parts per million (ppm),
not today’s few hundred ppm.
At 150 ppm, many plants
would die of CO2 starvation.
More CO2 is good for the world,
which has been in a CO2 famine
for tens of millions of years
-- one or two thousand ppm
would be ideal for the biosphere.
Hysterical attempts
to drive CO2 levels
below 350 ppm,
or some other value,
are not science.
Over most of the geological history
of the Earth, CO2 levels have been
much higher than now.
Yet ocean acidification
was not a problem;
corals flourished, leaving
extensive fossil reefs
for us to study today.
The only effect
of more atmospheric CO2
over the past century,
that no one debates,
has been the
satellite-observed
'greening of the Earth'.
'greening of the Earth'.
The claim that more CO2
has led to more extreme weather,
including tornadoes, hurricanes,
droughts, floods, blizzards, etc.
are lies, not based on data.
Extreme weather
is not increasing.
The current sea level rise
of about 2 mm/year would give
about 20 cm, or 8 inches,
of sea level rise over a century.
For comparison,
at Coney Island,
Brooklyn, NY,
the sea level
at high tide
is typically
four feet higher
than at low tide.
For poor people
-- most of those
living on Earth --
living on Earth --
depriving them
of the benefits
of affordable,
reliable energy
from fossil fuels,
that can't be replaced
by the intermittent,
inefficient
alternative energy,
from low density
energy sources
such as solar energy
or wind power,
is immoral.
Climate models don’t work.
They have predicted
almost three times
more warming
than has been
observed.
Even if you assumed
that CO2 caused 100%
of the warming since 1950
( with no scientific proof
that is true, and then extrapolated
that worst case warming rate
into the future ),
that only means
it would take
at least 600 years
for the average
global temperature
to rise +2 degrees C.

( from about 15 degrees C.,
to about 17 degrees C. )
