BACKGROUND:
Our planet has a
constantly changing
climate.
Antarctica ice core
studies identified many
mild warming/cooling
cycles in the past few
hundred thousand years.
Those temperature cycles
lasted hundreds of years
-- gradual warming
followed by gradual
cooling.
Every warming period
was followed by
a cooling period,
for a complete cycle.
Our planet has been in
an intermittent warming
trend since the late 1600s.
Climate alarmists would have
us believe that the current
warming trend is permanent
and dangerous.
They have no evidence of that,
but with climate alarmism,
the past climate doesn't matter.
U.S. compilations of the
global average temperature
begin in 1880
( some earlier measurements
are available for parts of Europe ).
That means ALL global
average temperatures
compilations from 1880
were from measurements
made DURING a warming trend.
Until that warming trend ends,
we should EXPECT frequent
"warmest on record"
media announcements,
at least once in a while,
and at most, every month !
New records are EXPECTED
and do not deserve
hysterical reactions from
the climate alarmists,
and scary headlines from
their friends in the media,
followed by the usual false
predictions of climate change
doom.
But that's exactly what we get.
Parts of Europe had intense
heat waves in late July 2019
-- heat from the Sahara desert
moved north.
That makes an interesting
headline, but the media went
too far, as they usually do,
claiming the continent’s
summer climate
had been rapidly
getting hotter
in the summers.
I checked the historical
temperature data and found
quite a few exceptions.
Below are charts of unaltered data,
from the Japan Meteorology Agency,
for several locations in northern Europe
that had long-term datasets available.
They show no July warming trend
over the past few decades.
Ireland:
For six stations in Ireland
-- the average July temperatures
have been cooling off over the
past three decades, even though
three stations are located at airports,
which should be getting busier,
and warmer, over time:
Sweden:
July temperatures have
changed very little
in the past two decades:
Finland:
Five of six weather stations
show no July warming trend
over the past two decades:
The U.S. Commerce Dept.'s
NOAA claims a “new global
July record” in July 2019
for their global average
of surface measurements:
Unfortunately, the NOAA chart
above claims record heat
in areas where there were
no thermometers !
When there are no thermometers,
or data are missing from some
weather stations, the numbers
are still needed for compiling
a global average, so they are
wild guessed by NOAA
bureaucrats ( aka "infilled" ).
The NOAA chart below
was NOT presented
to the public.
It shows temperature
anomalies -- changes
in temperatures from
a 30 - year average,
(aka "base period")
from 1981 to 2010,
to July 2019.
Only land areas
are shown
on the chart below.
The gray portions
of the chart
had no data,
so required wild
guessing (infilling)
by government
bureaucrats,
most of whom
would prefer to see
lots of global warming.
Some wild guesses
are even claimed to be
heat records !
Note that there are some
fairly large gray areas
with no measurements:
NOAA surface
thermometers
are NOT global,
and were
never intended
to be used
for calculating
an accurate
global average
temperature.
Land and ocean
coverage are
incomplete.
Weather satellites
in the troposphere
are different -- they
require very little
"infilling" (guessing)
-- only for small areas
near both poles.
And they say July 2019
was the 4th warmest July
since their records began
in 1979.
Of course climate alarmists
completely ignore weather
satellite data, which they
can not manipulate
with their infilling and
frequent, arbitrary
"adjustments",
that almost always
create MORE
global warming
out of thin air.
Weather satellites measuring
in the troposphere should find
LESS warming than near Earth's
surface, because oceans (71%
of the surface) are slow to warm
from the troposphere, where
the relevant greenhouse gas
warming takes place.
But surface "measurements"
reflect MORE warming than
measured in the consistent
environment of the troposphere,
which is VERY suspicious.
It's also VERY suspicious
that surface temperature
"adjustments" rarely
REDUCE the rate
of global warming.

satellite chart
for July 2019:
