DATA MINING
( A DECEPTION ):
-- BBC reporter
Jonathan Amos
reported Greenland
is now losing ice
seven times faster
than it was in the 1990s.
Source:
-- In the early 90s,
the rate of ice loss
would cause about
1mm of sea level rise
per decade -- it's now
running at roughly
7mm of sea level rise
per decade.
-- In an average year,
Greenland sheds
about 250 billion tonnes
of ice.
This year was more
like 370 billion tonnes.

THE UNBIASED TRUTH
In 2003, 16 years earlier
the same BBC reporter,
Jonathan Amos,
reported that Greenland
had experienced
reported that Greenland
had experienced
a significant COOLING
over the previous 40 years.

( see 2003 headline, below )
Putting all Greenland
information together,
for the whole story:
(A)
Greenland temperatures
fell by 1.29 degrees C.
between 1958 and 2001,
(B)
Greenland temperatures
have since recovered
to levels similar to the
1930s.
1930s.
That's no apocalypse.
The blue and red
temperature anomaly
chart at the end
of this article
shows

Greenland's
temperatures
in the
temperatures
in the
1930s
and
1940s,
and
1940s,
were about
the same
the same
as today !
In 2003,
reporter Amos
had reported
that Greenland
warming
and cooling
and cooling
were part of
a natural ocean
temperature cycle,
linked to the NAO
( North Atlantic Oscillation ).
Dr Edward Hanna,
from the Institute of
Marine Studies at the
University of Plymouth,
UK, had said
"Certainly
in the late 1990s,
there was
some warming
but that’s just over
a very short period.
There are a lot
of natural cycles
in regional climate
and if you take
a longer trend
over the last
40 or 50 years
then there
has been
a statistically
significant
cooling,
particularly in
south-western
coastal Greenland."
The NAO is
a natural, recurring
pressure pattern
that has
a profound impact
on the weather in the
North Atlantic region.
The NAO
is likely linked with
cyclical temperature
changes affecting
Greenland's
ice melting rate,
unrelated to the
general global
warming.
Meaning we can
expect to see
the cooling trend
return to Greenland
soon, slowing the
ice melt rate,
for 30 years or so,
ice melt rate,
for 30 years or so,
linked to the NAO.
Reporter Amos
correctly noted this
in his 2003 BBC report.
Two deceptions in
the 2019 BBC report:
( I )
The First BBC Lie:
In 2019, Mr. Amos
ONLY compared
ice melt rates now,
during the
warm phase
warm phase
of the NAO cycle,
with those from
the cool phase
of the NAO cycle,
claimed the
melting rate is
rapidly accelerating,
without mentioning
that natural ocean
temperature cycle.
(2)
The second BBC lie:
Extrapolating
the latest warming trend
all the way out to 2100,
completely ignoring
the NAO ocean
warming / cooling cycle
... and ignoring data
showing that NAO cycle
is still happening
( Greenland's rate of ice melt
HAS slowed since 2012 ).
