As of the mid-1970s,
the “consensus”
among climate scientists
was the globe had
warmed by +0.6°C
from 1880 to 1940.
And then cooled by
-0.3 degrees C. (to -0.4)
from 1940 to 1970.
After many
arbitrary
"adjustments"
in the past
two decades,
the +0.6 degree C.
global warming
is now reported as
+0.1 degrees C. warming.
The -0.3 degree C.
global cooling
is now reported as
-0.05 degree C. cooling.
This is science fraud !
About 45 years ago,
the “consensus” was:
( summarized by Williamson, 1975 )
1.
The Medieval Warm Period
was about +1 degree C.
warmer than present
while the Arctic was
“largely ice-free”,
+4 degrees C. warmer,
allowing the Vikings
to navigate through
open waters
because there was
“no or very little ice”.
2.
The island of Spitsbergen,
1,237 km from the North Pole,
and home to over 2,000 people,
“benefited” because it
warmed by +8 degrees C.,
between 1900 and 1940,
resulting in 7 months of
sea-ice free regional waters,
up from 3 months in the 1800s.
3.
Central England temperatures
dropped -0.5 degrees C.
between the 1930s to the 1950s.
4.
Pack-ice off northern and
eastern iceland returned to
its higher 1880s extent
between 1958 and 1975.
5.
In the 1960s,
the polar bears
were able to walk
across the sea (ice)
from Greenland
to Iceland,
for the first time
since the early 1900s.
They had survived
the 7 months per year
of sea-ice-free waters
during the 1920s-1940s.
In 1980 it was acceptable
to publish scientific
papers saying the
Northern Hemisphere
alone had warmed
by +1 degree C.
between 1880 and 1940,
and then cooled by
about the same amount
during the next
3 to 4 decades.
During the 2000s,
climate scientists
such as
Tom Wigley,
Phil Jones,
Michael Mann,
Gavin Schmidt, and
Stefan Rahmstorf,
exchanged e-mails
about “correcting”
the temperature data
by removing warming
from the 1940s “blip”
– which they said would be
“good”, and significant for
the global mean, because
the 1940s were “too warm” .
Phil Jones, overseer of
the British HadCRUT
temperature data,
admitted the pre-1980s
sea surface temperatures
in the Southern Hemisphere
are “mostly made up”
due to insufficient coverage.
He also corresponded
with a colleague about
“inventing” monthly
temperature anomalies
– which apparently was
“fun” to do.
