PolarRES - 💧Did you know that due to sea water freezing, almost doubles in size each winter?

📉Sadly, findings from @Dr_Gilbz show that Antarctic sea ice extent fell to record lows in 2023

Signs found of worryingly fast Antarctic ice melt - New Zealand expedition

"The changes to the sea-ice indicate that in the coming decades coastal cities will need to be reconfigured because of sea level rise, Stevens said.

While the effects these changes will cause to ecosystems will impact mammals like penguins, whales and seals, and weather systems would also change around the Southern Ocean."

About that ozone hole..

Doesn't seem to be healing very fast - not due to necessarily but a quirk of the system means a colder - which is delaying things.
Really good piece from my colleagues at DMI on it (in danish but DeepL works really well for translation):

" on may not have much immunity to the disease, since the virus has not been documented on the continent until now. Outbreaks among penguins in South America and Africa show their vulnerability. The birds, which like to waddle together in packed colonies, are not particularly good at social distancing."

It matters where the water comes from.

Why does the loss of ice in Antarctica affect Northern Europe more than melt in Greenland?

Apparently, many people are confused about how global and local sea level rise are not the same so I wrote a brief blog post to try and explain it.

Posting again for the European morning crowd..

This chap wandered away from his group & is now stubbornly standing alone on algae polluted icy snow. It's a chinstrap penguin part of a large colony at Palaver point in Antarctica.

In , the Twaites Tongue has disintegrated, which could cause a further chain reaction and rising sea levels. This was the result of Iceberg B22a, which allowed monster waves from southern storms to batter it. Rapidly melting ice packs on both the north and south polar regions is accelerating rapid ocean rises.
