I bet you didn't read this news
in the mainstream media, about
glaciers GROWING in Greenland,
or perhaps you were told Greenland
glaciers were MELTING ?
Remember that truth
is not a leftist value !
How about some
climate change truth,
for a change ?
Since 2012, there has been
an abrupt slowing of Greenland
glacier melt rates, and a trend
reversal to cooling and ice growth
in 2017 - 2018.
Large regions of the oceans
surrounding Greenland
have been rapidly cooling
– by as much as 1 to 2°C.
in the past few years.
In 2018, 26 of Greenland’s
47 largest glaciers were
either stable, or grew in size.
The change from 2016-2017
to 2017-2018, in the net area
of the 47 monitored
Greenland glaciers,
shows an INCREASE
of +4.1 km2, which makes
2018 the ONLY year with
a POSITIVE (ice gain) balance
since data were first collected
in 2008.
"Of the monitored glaciers,
21 retreated and 12 grew in size.
In the remaining 14 glaciers
the changes in area were
(insignificant) within ±0.2 km2."

Of the 6 largest Greenland glaciers,
4 grew, while 2 retreated.
Since 2012, ice loss
has been “minor”
to “modest” due to
the dramatic
melting slowdown.
Summer average temperatures
for 2018 were LOWER than the
2008-2018 average, by more than
one standard deviation.
Since 2000, the extent of the
non-snow-covered areas
of Greenland has increased
by 500 km² per year.

"Observations from
the 18 weather stations
in the melting region
of the (Greenland) Ice Sheet
indicate that the a
verage degree of melting
was the lowest recorded
during the 10 years
in which observations have
been made (2008-2018)."
"Only two out of eight
measurement positions
(NUK and KAN)
registered more melting
than normal, although
these figures did not
lie outside measurement
uncertainties."
" ... summer temperatures
in June, July and August (2018)
were lower than average for
2008- 2018 at all PROMICE
measurement stations (by more
than one standard deviation
along the northern, northwestern
and southern edge of the Ice Sheet). "
"Looking at all measurements
in the months from January
to August (2018), 28% of the
monthly temperatures
were more than one
standard deviation
below the mean. "
"And only 3% were more than
one standard deviation
above the mean."
"The extent of non-snow-covered areas
has increased during the period 2000-2018
by an average of 500 km2 per year.
Although this increase is not significant,
it nevertheless demonstrates
that there has been a little more melting
than accumulation of ice since 2000."
"The area of the 47 largest glaciers
has been monitored by the
Sentinel-2, LANDSAT and
ASTER satellites since 1999."
"Monitoring reveals that during
the last six years from 2012-2013
until 2017-2018, there has been
a minor annual loss in terms
of the glaciers’ area."
"If only the 6 largest glaciers
are considered, they have grown
only slightly overall. "
"This applies to Jakobshavn,
Kangerdlugssuaq, Helheim,
Petermann, Zachariae and
79° Glacier, which increased
their area by an average of
+3.7 km2 during the year."
"Two of these glaciers retreated,
however, whereas the other four
grew in size."
"the total change in the area of
47 of the largest marine terminating
glaciers in Greenland ... shows that
since 2012 these glaciers have lost area
to a modest extent."
Jakobshavn Isbrae, Greenland’s
largest contributing glacier
to sea level rise in recent decades,
has stopped melting and begun
advancing in line with an abrupt
-2°C cooling in the region.
The glacier is now thickening
at a rate of 20 meters per year.
Temperature trends across the
ice-free part of Greenland
indicate cooling since 2001.
Central Greenland has undergone
a slight cooling trend since 2005.
Ocean temperatures in the region
have cooled to levels not seen
since the 1980s.
Greenland’s climate lags the
North Atlantic’s temperature.
So further cooling
and glacier thickening
may be coming.
These trends are NOT
what would be expected
in a rapidly warming world.
