Some temperature
stations along
the coast of the
Antarctic Peninsula
-- the warmest part
of the continent --
indicate
“marked statistically
significant cooling”
since 1991, with the
Larsen Ice Shelf
cooling at a rate of
-1.1°C per decade.
Bozkurt et al., 2020
“Observed near-surface
temperature trends
indicate important contrasts
between summer and autumn
for the period 1991−2015.
A notable summer cooling
exists on the northern peninsula
(Frei and Marambio stations)
and leeward side
(Larsen Ice Shelf station).
The largest
summer cooling
trend is observed
at the Larsen
Ice Shelf station
[−0.92°C (10 yr)−1,
p < 0.05].
On the other hand,
in autumn, San Martin
station on the central
windward coasts
exhibits the largest
warming trend
[+0.64°C (10 yr)−1 ,
p < 0.05].
Autumn warming
is also notable at
the other stations
except the Larsen
Ice Shelf station.
At the annual
time scale,
there is a clear
warming trend
at San Martin station
[+0.52°C (10 yr)−1 ,
p < 0.05],
whereas at
a close latitude
on the leeward side
the Larsen Ice
Shelf station
exhibits a
marked statistically
significant cooling
[−1.1°C (10 yr)−1].”
