💙 The annual cycle of the Southern Ocean freezing and melting is like a heartbeat for 🌏. This animation shows #Antarctic sea ice coverage pulsing between winter 🔷 and summer 🔶over 45 years since satellite records began in 1978.

1. Over 40% of Antarctica’s ice shelves reduced in volume over 25 years. Almost all the ice shelves in western #Antarctica lost ice from 1997 to 2021. In contrast, most on the eastern side stayed the same or increased in volume.

Brutal analogy - 🇦🇺 as the world's drug(coal) dealer...
Why the 'drug dealers defence' doesn't work for exporting coal. It's actually Economics 101 https://t.co/alYwcKGVCJ via @ConversationEDU

🚨 Sea ice emergency summit: "As people who have studied the Antarctic and Southern Ocean systems for decades these recent changes are deeply alarming. This group calls for a dramatic reduction in greenhouse gas emissions now."

"As Doddridge and Purich’s research is only weeks old, other Antarctic scientists are yet to fall in behind their hypothesis."
🤣Come on colleagues - you've had *weeks*. What's taking so long?! 🤣
We have a new @saef_arc research fellow position (Level A or B) in Melbourne to understand teleconnections between the tropics and Antarctica working closely with researchers @BOM_au. Apply at https://t.co/m1x13GDxQy by 15 October and come join us in @MonashEAE !
Record-low sea ice coverage around Antarctica co-occurred with substantial subsurface ocean warming, suggesting that the mechanisms that govern Antarctic sea ice have changed.

For most of us, Antarctic sea ice is something far away we may have seen on a doco. But those ice-sheets are a vital part of Earth’s climate processes & the freeze | melt cycle has changed. Is this the 'new abnormal'? https://t.co/GtXeZ2Dm6k

About that record low Antarctic Sea Ice. Yup regime shift “Here we show the confluence of Southern Ocean subsurface warming & record [sea ice] minima and suggest that ocean warming has played a role in pushing Antarctic sea ice into a new low-extent state” https://t.co/M8jylT5ZY9
