Antarctica Melts Under Its Hottest Days on Record

Recommended Posts

From NASA:

On February 6, 2020, weather stations recorded the hottest temperature on record for Antarctica. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)—around the same temperature as Los Angeles that day. The warm spell caused widespread melting on nearby glaciers.

The warm temperatures arrived on February 5 and continued until February 13, 2020. The images above show melting on the ice cap of Eagle Island and were acquired by the Operational Land Imager (OLI) on Landsat 8 on February 4 and February 13, 2020.

The heat is apparent on the map below, which shows temperatures across the Antarctic Peninsula on February 9, 2020. The map was derived from the Goddard Earth Observing System (GEOS) model, and represents air temperatures at 2 meters (about 6.5 feet) above the ground. The darkest red areas are where the model shows temperatures surpassing 10°C (50°F).

Mauri Pelto, a glaciologist at Nichols College observed that during the warming event, around 1.5 square kilometers (0.9 square miles) of snowpack became saturated with meltwater (shown in blue above)...

This February heatwave was the third major melt event of the 2019-2020 summer, following warm spells in November 2019 and January 2020. “If you think about this one event in February, it isn’t that significant,” said Pelto. “It’s more significant that these events are coming more frequently.“

What about the lowest temperature ever recorded for Greenland which occurred January 2nd 2020 -86.8F?    https://electroverse.net/greenland-just-set-a-new-all-time-record-low-temperature/

 

Of course this stuff never makes the mainstream news. 

Thanks,  the article made me chuckle:

"Rarely, for the times we’re in (where historically low solar activity is weakening the jet stream, reverting it’s usual tight zonal flow to a wavy meridional one), the cold air has actually remained locked in the Arctic Circle, and the results have been punishing for the region.

Though skipping forward 7-or-so-days, another violent buckling of the jet stream looks due to arrive by mid-January, and should once-again funnel dangerously cold polar air masses to the lower-latitudes.

Watch out North America, as according to latest GFS runs, a pulse of brutal Arctic air will have engulfed practically all of Canada by Jan 09, and should have swept the Central & Western U.S. by Jan 17:

This could be big.

Prepare.

The cold times are returning, in line with historically low solar activity.

The jet stream is weakening, diverting brutal polar cold to the lower-latitudes:"

Meanwhile in Antarctica, the recent record wasn't an isolated event. Temperatures have been well above normal all summer (4th from top). Surface melting has been off the charts (2nd from top), causing below average surface mass balance (top) despite average snowfall ( link).

I just looked at the January 17-31 anomalies for the Central and Western U.S. It seems that the climate maps are wrong. ;)

They don't reflect the "brutal Arctic air" that was supposed to engulf practically all of Canada (warm anomalies, too!) before plunging into the United States. At second glance, early blooms are reported in many parts of the U.S. The promised cold never materialized. And that outcome is consistent with what one is seeing on a global scale more and more often with a warming climate.

That's my point. Greenland breaks an all-time record low and it is largely ignored by climate "scientists", MSM and makes only such wack job websites. The data is real, Greenland came very close to breaking the all-time record low for the northern hemisphere...

Summit station is a research site, uninhabited, 10500', Jan avg temp is around -40C, short record (roughly 30 years, with gaps), apparently not an all-time site record (colder temp in March 2011 below), during an extreme strat polar vortex event when mid and upper troposphere was very cold.

With no background on technical aspects of the record in the article, looks more like an opportunity to cherry pick and whine about the media.

the lowest temp for Greenland is actually -89 which occurred on the Summit research station on top of their ice cap back in the 80s.
