The "era of man made
CO2 emissions" started
roughly after 1940.
We have measured
the global average
temperature changes
after 1940.
I'm not satisfied
with all the infilling
(wild guessing)
required for surface
temperature compilations,
so I use the UAH
satellite data that starts
in 1979, whenever possible.
The ACTUAL
warming rate,
cause unknown,
in the 78 years
from 1940
through 2018,
is less than
+0.8 degrees C.
per century.
The average
climate model,
excluding the
Russian model,
obviously colluding
with Donald Trump,
predicts a FUTURE
warming rate of about
+3 degrees per century
-- QUADRUPLE the
ACTUAL warming rate
while lots of CO2
was added
to the atmosphere
from 1940 through 2018.
Any start point
other than 1940
(1950 would be okay)
is data mining.
Any short period of time
that had a warming rate
close to +0.3 degrees C.
per decade, would make
the average climate model
look good.
The only period of time
that really counts,
however, is from
1940 through 2018
-- the entire period
with lots of man made
CO2 emissions.
I could also accept
1950 through 2018,
since CO2 emissions
ramped up even more
after 1950.
Any other
time period
is data mining.
Our planet
has had
intermittent
global warming
for over 300 years,
since the late 1600s,
during the
Maunder Minimum,
low solar energy period,
during the "Little Ice Age".
The warming since then,
measured (real time)
in central England,
was at least +3 degrees C.
Very little of that warming,
(perhaps up to 15%)
could be blamed on
man made CO2
(as if anyone knew what CO2
really does in the atmosphere,
with any precision).
The warming since
the late 1600s
has been good news.
The warming since
the late 1600s
has been almost
entirely natural.
No one
in their right mind
would want to stop
that 300+ year
warming trend,
especially because of
what we've learned
in recent decades:
- The warming after 1979
was mainly at high latitudes,
mainly in the six coldest months
of the year, and mainly at night.
Ask the people
living in Alaska
if that's
good news,
or bad news,
for one example !
That's good news
warming for them
( and not at all visible
in a global average ) !
- Our planet is also
significantly greening
from more CO2 in the air.
.
.
.
That's the big picture,
of PAST climate change
-- all GOOD news.
Is it not strange that
FUTURE climate change
is ALWAYS predicted
to be BAD news.
The same BAD news
predictions have been
made every year,
for over three decades,
yet the predicted
BAD news climate,
never arrives !
The UAH weather satellite
data show no global warming
from early 2002 through
the end of 2018 --
why do the mainstream
media completely ignore
that flat trend ?
And the warming rate
predicted by the average
computer game model
is QUADRUPLE
the actual warming rate
from 1940 through 2018 !
And no one reports that
in the mainstream media !
.
.
So why is it that
climate change skeptics
spend so much time
debating tenth of a degree
global average temperature
anomalies, and so little time
spreading the news
that PAST climate change
has been mild, intermittent
and good news ... and there's
no logical reason to assume
FUTURE climate change
will be completely different?
For anyone less than
78 years old, fossil fuel
burning has been adding
a lot of CO2 to the
atmosphere for your
entire life.
And although no one knows
the exact effect of the CO2
on the global temperature,
the worst case, based on
actual past warming,
not computer games,
is global warming
of less than +0.8 degrees
warming per century
= totally harmless
-- pleasant, actually.
Even if you
cherry picked
data from 1979
through 2018,
the warming rate
(with the cause unknown)
was about +1 degree C.
per CO2 doubling
-- predicting about
+1 degree C.
global warming
in the next 125 years
(with +3ppm per year CO2 growth rate),
to the next 200 years
(with +2 ppm per year CO2 growth rate) !
And that worst case estimate
above assumes CO2 caused
ALL the warming since 1979,
with no scientific proof
CO2 caused ANY of the warming.
Any way you look at it,
PAST climate change
was mild, and good news.
There's no logical reason
to assume FUTURE
climate change
will be different.
The coming climate change
"crisis" is only in the overactive imaginations of devious leftists,
They are trying to scare people,
and then they claim
a more powerful
central government
is the ONLY "solution"
to their imaginary crisis.
Of course leftists
have always wanted
a more powerful
central government.
The imaginary coming
climate crisis is their
latest tool to get what
they've always wanted !
