Government
bureaucrats claim
that 2010-2019
has been the
warmest decade
in the entire
instrumental
record
( since 1880 ).
My comment:
That claim
is based on
temperature data
almost entirely
from the Northern
Hemisphere
before 1920.
Far from global
coverage
before 1979.
Near-global
only since 1979
(UAH satellite data)
The lack of
global coverage,
and huge amounts
of infilling
( wild guesses
for areas
missing data )
and repeated
adjustments,
mean data from
1880 to 1979
can not be trusted.
1800's era
thermometers
also tend
to read low.
Global warming
from 1880 to 1979,
claimed to be about
+0.5 degree C.,
but the correct
measurements
could just as well be
no warming at all.
.

It's claimed most
of the warming
after 1950 is due to
increasing carbon
dioxide (CO2)
in the atmosphere
from fossil fuel
burning.”
My comment:
No one knows
what percentage
of warming
is caused
by humans,
if any.
The correct
percentage
is between
0% and 100%.
The IPCC claim
is "over half"
-- a compromise,
but certainly not
a proven fact.
.
.
.
It's claimed that
global warming
will continue
into the future.
My comment:
It's also claimed
that CO2 levels
control the global
average temperature.
Except for the past
4.5 billion years,
where the only known
CO2 - temperature
correlation is that
temperature changes
lead to changes
in the CO2 level,
hundreds
of years later.
In recent centuries:
-- Global warming
is claimed for
1910 to 1940,
in spite of
very little
claimed change
in the CO2 level.
-- Global cooling
is claimed for
1940 to 1975,
in spite of
lots of CO2
added to the
atmosphere.
The correct answer
is no one knows
the future climate.
Predictions of an
environmental
or climate crisis
in the past 50 years
have been
100% wrong.
How many decades
of wrong climate
predictions
are required
before it becomes
obvious that
climate predictions
are very unreliable?
This planet supports
MORE life when
there is more CO2
in the atmosphere,
and higher latitudes
are warmer.
So I prefer
global warming,
over global cooling,
which are the
only two choices !
My plants
are thankful
for more CO2
in the air too
It seems that
people with PhD’s
are unwilling
to ever say
“I don’t know”
or
“No one knows”,
about the
future climate.
They prefer
to guess,
or just join
the consensus,
even when
a consensus
means nothing
in real science.
There is no
additional risk
from a mildly
warming planet
— we have
325 years
of mild global
warming
since the 1690s
to prove that.
The ONLY risk
is a global gross
overreaction
to a non-existent
climate problem
— attacking
reliable,
consistent,
inexpensive
sources of
electricity,
and wanting to
replace them
with unreliable,
inconsistent and
expensive solar
and wind power.
THAT is an
existential
threat !
