Climate "scientists" are
constantly "adjusting"
historical temperature
data again and again.
Almost every
"adjustment"
creates more
global warming
out of thin air.
In the latest
NASA-GISS version
of the global
average temperature,
called V4, the
V4 “unadjusted”
data sets
are different from the
V3 "unadjusted"
data sets !
NASA even adjusts
their "unadjusted" data !
In the UK, their HadCRUT
dataset has the same
quality concern -- repeated
arbitrary data "adjustments".
HadCRUT3, published in 2014,
shows no warming from about
2001-2013.
But the latest "data",
HadCRUT4.6,
is warmer from the
repeated "adjustments".
Consider the 2013 vs. 2001
global average temperature
warming -- it has been
repeatedly increased
in successive HadCRUT versions:
HadCRUT 2013 minus 2001
version Global Warming
4.1.1 +0.023 degrees C.
4.2.0 +0.050
4.3.0 +0.053
4.4.0 +0.059
4.5.0 +0.073 degrees C.
In addition to the above
"adjustments", the British
Met(eorilogical) Office
also "adjusted" sea surface
temperatures (SSTs) in their
latest data set, called HadSST4
( their HadCRUT4 global average
land plus sea temperature
had included their HadSST3
sea surface temperature ).
The graph below compares
the current version HadSST3
with the proposed new version,
HadSST4:
Warming has been
"adjusted" upward by +0.1C,
which sounds very small,
but is actually a 10% increase
of total global warming !
In the next chart, below:
-- Red diamonds are raw data,
-- Green diamonds are HadSST3,
-- Black line is the new HadSST4
-- Grey shading representing uncertainty.
Since 2000, the raw data show
no sea temperature trend at all.
HadSST3 adjusted the
raw data trend upwards
to create sea surface warming.
HadSST4 adjusted the
sea surface warming trend
upwards again, doubling
the previous adjustment.
The blue and the orange
lines in the chart above
are two other efforts
to measure the sea
surface temperature,
ERSST and COBE-SST.
Both have
a warming trend
greater than HadSST3,
so I suppose the
UK Met Office
had an excuse to
adjust their own SST
upwards to keep up ?
The Met Office calls this
an adjustment made to
“reduced discrepancy
between datasets”.
I call it yet another
"government bureaucrat
steaming pile of farm
animal digestive waste
products adjustment",
implemented to boost
historical global warming,
yet again, only done
for political reasons,
for political reasons,
not scientific reasons !
