#Antarctica might be thousands of kilometres away, but it affects us all like no other continent. As world leaders gather for the #COP28 climate summit, we bring you a report on how even the most remote place on Earth is beginning to crumble...

This is the year that much changed in our understanding of #Antarctica, @voooos wrote some very good articles on the Southern continent and why it matters.

We’re super excited to announce the addition of 2 new Penguins to our (very local, plush) Penguin Colony: 2 Gentoo penguins (far right in photo) named GenOne & GenTwo. 😉 We now have 5 Emperor + 2 Gentoo Penguins! 😍 It’s probably the only penguin colony in Tucson, AZ, USA! 🐧🐧🐧🐧🐧🐧🐧

This Antarctic glacier dramatically retreated. Then, its ice shelf totally collapsed

Cadman Glacier in Antarctica retreated 5 miles in just 2.5 years, causing its ice shelf to collapse, according to scientists who used satellite images and ocean measurements. Higher ocean temperatures likely hastened the glacier’s deterioration, which contributes to global sea level rise. This indicates potential similar threats for neighboring glaciers.

Waiting at the hairdresser so time for one of my periodic #ClearTheTabs threads on random stuff I have open in my #Firefox...

First up a paper I think @DrEvanGowan shared on Palaeo #SeaLevels from Australia that appear to confirm the vulnerability of #Antarctica to loss under #ClimateChange 1/many

UN Chief Calls Antarctica ‘Sleeping Giant… Being Awoken by Climate Chaos’

“It is profoundly shocking to stand on the ice of Antarctica and hear directly from scientists how fast the ice is disappearing.”

#30DayMapChallenge 🗺️ Day 2️⃣5️⃣: #Antarctica 🇦🇶

I wonder if I can get away with making a map about Antarctica but without showing any part of it! 😉

I managed to do just that by showing how involved the countries of the world are in the coldest continent! (Again I used my favorite #CahillConcialdi map projection—any guesses as to what I’ll be doing for Day 30? 😂)

The countries are classified along 4 axes...

Does #Europe know just how awesome the #BeyondEPICA project is?

For the late crowd .

Ruth_Mottram - I reblogged my part of videnskab.dk's series on . I was interviewed on in the system, why the is so low, what are the consequences for the and how our @OceanIceEU project will help to fill the gaps.

Enjoy. :)

Paris polar summit: Melting ice takes center stage

Recent studies have shown vital ice sheets are melting at unprecedented rates. Scientists, politicians and NGOs are gathering in Paris for a Polar Summit.

Scientists discover hidden landscape ‘frozen in time’ under Antarctic ice

Scientists have discovered a vast, hidden landscape of hills and valleys carved by ancient rivers that has been “frozen in time” under the Antarctic ice for millions of years.

Lots of discussion @OceanIceEU about what is going on in #Antarctica put me in mind of @micefearboggis' excellent post on the weird weather we're having. I couldn't put it better myself....

"This year, getting Antarctic-wide temperature anomalies right has depended on getting the right balance of very large positive and negative anomalies. In an area with scarce and sometimes unreliable observations this isn’t easy to do. "
A multitude of possibly unsatisfying answers

Scientists discover hidden landscape "frozen in time" under Antarctic ice for millions of years.

CBS News reports: "This landscape, which is bigger than Belgium, has remained untouched for potentially more than 34 million years, but human-driven global warming could threaten to expose it."
