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.

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.”

You and I no longer live in the natural world into which we were born. It's already very different, and the pace of change is accelerating.

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.

Most of the lines run in tandem as a sine wave, with a low in March and a high in September, but this year, 2023, plotted in light blue, falls well below the other years, starting in mid-May, and as of September is well below all other recorded years by a large margin

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.”

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.

"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."
