My sister, Cree, is a badass adventurer and is going to #antarctica. You can follow her story of working at the South Pole station on #substack. https://open.substack.com/pub/creelef/p/ive-landed-a-kitchen-job-in-antarctica?r=2swcyp&utm_medium=ios&utm_campaign=post
The preparations for our #fieldwork in #Antarctica are in full swing. Last week we went to the Alps for glacier and safety training. We were joined by colleagues from Uni Cologne and TU Dresden. I can't wait to put (some of) this knowledge into practice.
I really like this blog. It's a person who is currently working an IT contract in Antarctica and is blogging about what it's like living there.
Antarctic sea ice fell to an all-time lowest seasonal peak, reaching about 398,000 square miles below the previous record in 1986, according to the National Snow and Ice Data Center.
Axios quotes a scientist: "The trend in the past five months is so different from the past 45 years that all of us sat up and took notice."

According to a new study, Antarctica experienced the sharpest heatwave ever seen on Earth last week. The temperature at Concordia Research Station, located on the Antarctic Plateau, soared to minus-11.5 Celsius, which is 38.5 Celsius above normal. The heatwave could have serious consequences for the ice sheet, the wildlife and the global climate.
"Antarctica has likely broken a new record for the lowest annual maximum amount of sea ice around the continent, beating the previous low by a million square kilometres."

Scientists are now reporting on the "greening" of Antarctica. And that's NOT a good thing...
___________________________
As Antarctica is mostly covered in ice and snow, there previously hasn't been much space left for plants to grow. There are no trees or shrubs, and the plants that do exist are limited to a few islands and along the western Antarctic Peninsula.
However, as global temperatures continue to rise and ice in Antarctica continues to melt, researchers have found that plants on the continent are growing more quickly.
Comparing the results with surveys from the previous 50 years, they found that the sites had not only become more densely populated by the plants, but that they had also grown faster each year as the climate got warmer.
The results were staggering, with the Antarctic hair grass growing as much in 2009-2019 as it had in the entire 50 years from 1960 from 2009.
The Antarctic pearlwort moved even faster, growing five times more in the same periods.
Peter Convey, at the British Antarctic Survey, touched on the impact of accelerated growth as he told New Scientist: “The most novel feature of this is not the idea that something is growing faster. It’s that we think we’re starting to see what is almost like a step change or a tipping point.”

Antarctic sea ice peaks every year in September. This year (the thin light blue line, in the graph below), there's less of it, by a wide margin, than has been recorded since 1981.

"Each September #Antarctica’s #SeaIce reaches its maximum extent. The average between 1981 and 2010 was 18.71m sq km.
The 2023 maximum was 1.75m sq km below the long term average and about 1m sq km below the previous record low maximum set in 1986."
Sea ice that packs the ocean around #Antarctica hit record-low levels this winter, adding to scientists' fears the impact of #climatechange at the southern pole is ramping up. #globalwarming

#Antarctica has likely broken a new record for the lowest annual maximum amount of sea ice around the continent, beating the previous low by a million square kilometres.
The new mark is the latest in a string of records for the continent’s sea ice, as scientists fear global heating could have shifted the region into a new era of disappearing ice with far reaching consequences for the world’s #climate and sea levels. #ClimateCrisis
Antarctic sea ice shrinks to lowest annual maximum level on record, data shows | Antarctica | The Guardian https://www.theguardian.com/world/2023/sep/26/antarctic-sea-ice-shrinks-to-lowest-annual-maximum-level-on-record-data-shows
This year, #Antarctica reached its annual max on Sept 10, ~13 days earlier than avg. At that time, the annual #ice coverage was at a record low of 6.55M sq miles — a whopping 398k sq miles lower than the previous rec low set in 1986.
“It is surprisingly low,” said Twila Moon, an ice scientist at #NSIDC. “We have this extreme low minimum & there hasn’t been any ability to recover towards previous higher extents during the Antarctic fall &…winter...We’re starting to see this yr round influence.”
Sea ice around the #polar regions grows & #melts w/the seasons. In #Antarctica, #SeaIce typically hits its minimum coverage at the end of the Southern Hemisphere’s summer around Feb. It reaches its max extent at the end of winter in mid- to late Sept. This Feb, scientists reported Antarctic #floating #SeaIce hit an all-time low at the end of the summer — & sea ice growth continued to remain slow through winter.
#Antarctica just hit a record low in #SeaIce — by a lot
Sea ice extent around #Arctic was the 6th lowest on record as well
Sea ice levels around Antarctica just registered a record low — & by a wide margin — as winter comes to a close, according to the National Snow & Ice Data Center (#NSIDC). This significant milestone adds worry that Antarctic sea ice may be entering a state of decline brought on by #ClimateChange.

Scientists found the most intense #HeatWave ever recorded.
In March 2022, temps near the east coast of #Antarctica spiked 70°F (39°C) above normal — making it the most intense recorded heat wave to occur anywhere on #Earth…. Scientists elsewhere said such a high in that region of the world was unthinkable.

Researchers recently discovered that the most intense heat wave ever recorded happened last March.
And it was in the coldest region on Earth.
Eastern Antarctica saw a spike of about 70 degrees Fahrenheit above average that month, according to a study published in the peer-reviewed journal Geophysical Research Letters. The region was at 5 degrees Fahrenheit at the peak of the heat wave when it should've been near -65.2 degrees Fahrenheit, the study says.

i've long thought that this extended experiment we're doing on our own planet called #ClimateChange had the potential to really shock us...
and this is pretty GD shocking.

The record low #SeaIce situation around #Antarctica has taken a lot of the attention this year, but #Greenland also had a #StrangeIce year - smashing monthly mean temperature records in July and again in August - right at the top of the ice sheet at #SummitStation
In the mean time it's the 27th year in a row that @greenlandicesheet has net lost ice.
It's been a very interesting #Wx situation this year - I might blog this later, some details:

"In West #Antarctica, a region considered particularly vulnerable to warming with an ice sheet that could push up global sea levels by several metres if it collapsed, the study found warming at twice the rate suggested by climate models.
Climate scientists have long expected that polar regions would warm faster than the rest of the planet – a phenomenon known as polar amplification – & this has been seen in the Arctic."

The ferry I am currently on has just passed the #PenguinsFPSO a floating storage and production operations vessel that, #Shell assures us here, "is an attractive opportunity with a competitive forward looking price".
And all I can think of is the paper I commented on last week about emperor penguin chicks that failed to fledge because the #SeaIce around #Antarctica broke up early.
#FossilFuels #OilAndGas #ClimateChange #EmperorPenguins
In case you haven't yet had your daily dose of climate $&!*: "Reduction in sea ice in Antarctica has resulted in the deaths of an estimated [5,000 to] 10,000 emperor penguin chicks [in 2023 alone].
"In 2022, satellites recorded a colony of emperor penguins disappearing into the Bellingshausen Sea as the ice they were living on melted away.
"The chicks had not fully developed waterproof feathers and they most likely froze to death."
https://www.youtube.com/watch?v=12J9uJBjHhw @BBCRD #climate #heat #Antarctica
brutal.
"A catastrophic die-off of emperor penguin chicks has been observed in the Antarctic, with up to 10,000 young birds estimated to have been killed.
"The sea-ice underneath the chicks melted and broke apart before they could develop the waterproof feathers needed to swim in the ocean.
"The birds most likely drowned or froze to death."

More alarming news from #Antarctica this morning as a new study finds that the continent's fragile environments "may well be subject to considerable stress and damage in future years and decades."
#ClimateChange is having a significant impact on Antarctica's ice sheets, #climate and ecosystems, with far-reaching global consequences.
Decisions made in the next years will determine whether Antarctica suffers dramatic changes that result in global sea levels rise.
