If you measure
from the depths
of the natural
Little Ice Age,
in the 1690s,
the global
average
temperature
is warmer,
probably by
at least
+2 degrees C.
With a longer
perspective,
our era's climate
is not remarkable.
Remember
that global
surface average
temperatures
were first compiled
DURING a long term
global warming trend.
And that means
"new records"
are expected
to happen
regularly,
until the warming
trend ends, and a
cooking trend begins.
The most credible
surface temperature
numbers are from
the United States.
For the U.S.,
2019 was cooler
than 2005, 2006,
2007, 2010, 2011,
2012, 2015, 2016,
2017 and 2018.
The American
temperature
records show
the number of
really hot days
were declining
over the
past century.

NASA’s
Goddard Institute
for Space Studies
( GISS )
clings to the coolest
available period
( 1951-80 )
for their baseline.
The National
Oceanographic
and Atmospheric
Administration,
( NOAA )
equally alarmist
in its views,
uses 1981-2000.
NOAA and
NASA GISS
are claiming
their data says
the world in 2019
was the second
warmest ever, and the
decade of 2010-2019
was the hottest ever
( by a few hundredths
of a degree C. ).
First of all,
"ever"
really means
really means
after Word War II --
there were
no global data
before that,
forcing a lot of
guessing of the
temperatures
for areas with
insufficient
thermometer
coverage.
I have argued here
that the CURRENT
surface temperatures
still do not have
sufficient global
coverage.
When
measuring
measuring
temperatures
outside of
a laboratory,
there's no way
to be accurate
to the nearest
tenth of
a degree C.,

much less
a few
hundredths

of a degree C.
Including
error bars

Error bars would
stop the scientific
fraud of claiming
one year’s rank
by an amount
smaller than
the size of the

margin of error.
Spurious
accuracy
accuracy
( sometimes called
"false precision" )
is quoting the
global average
temperature
in hundredths
of a degree C.,
in spite of a
conservative
a margin of error
of at least
+/- 0.5 degrees C.
That's science fraud.
