UAH South Pole
weather satellite
temperature data
happen to start
in 1979
Version 6.0, LT
( lower atmosphere ).
.
You could claim a warming
trend from 1979 through 2018,
if you cherry picked
1979 as your starting year.
.
For many people
who like that message,
that's enough "analysis".
.
But not for me.
.
1979 was an unusually
cold year, so using a
1979 starting point for a
temperature trend line,
would be deceptive
data mining.
.
If you had started
the trend line in 1980,
the warming trend
would disappear.
.
Change the starting year,
by one year, and the
trend changes ?
.
That tells you a trend line
is not a good way
to describe those numbers.
.
How about comparing
one full year,
with another full year,
38 years earlier?
.
If you compared
the year 2018,
with the year 1980,
you could say 2018
was colder than 1980:
.
(A)
1980 average monthly
temperature anomaly
= +0.55 degrees C.
(versus the 1981 to 2010 average)
.
(B)
2018 average monthly
temperature anomaly
= +0.03 degrees C.
.
Conclusion:
Antarctica was cooler
in 2018, than in 1980 !
.
.
.
.
That's enough data mining.
.
Here's a honest analysis:
.
A look at all the available
UAH South Pole data
on a chart (see below)
shows a flat long-term trend,
with lots of variations
from year to year.
.
Antarctica temperature change
has been much different than
Arctic temperature change,
where significant warming
since the 1970s has been
assumed to be caused by CO2.
.
The flat temperature trend
in Antarctica is very different.
.
It is contrary evidence
for the claim that CO2
is warming our planet.
.
The greenhouse theory
says Antarctica warming
should be similar
to Arctic warming
-- both dry areas
should have a lot
more warming than the
humid tropics
... but that's
not happening !
.
.
.
.
Trends and averages
can be a problem.
At worst, they are deceptive.
.
At best, they hide details.
.
That's why global averages
and trends are loved
by climate alarmists.
.
.
.
One important detail
about Antarctica
is how difficult it is
to measure the
temperature there
accurately, even
with satellites.
.
An even more important
detail is the small amount
of local warming
on some edges of
the Antarctica glacier,
meaning the rest
of the continent
MUST be getting
colder since 1980.
.
The local Antarctica warming
is in various locations
near known underseas
volcanoes -- a very uneven
temperature change pattern
that could NOT have been
caused by greenhouse gasses.
Here's another Antarctica dataset:
