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'? theconversation.com/devastatingly-… University of Tasmania Australian Antarctic Program Partnership Ed Doddridge

Sea ice around Antarctica follows a predictable seasonal cycle – but we’ve now experienced a sudden dramatic loss. ❄️ As Ed Doddridge (University of Tasmania) + Ariaan Purich (Monash University) found, Antarctic sea ice may have entered "a new state of diminished coverage". theconversation.com/devastatingly-…

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” nature.com/articles/s4324…

New research shows low #Antarctic sea ice may be the new normal. Ariaan Purich & Ed Doddridge suggest in Nature Reviews Earth & Environment 🌈 that ocean warming has played a role in pushing sea ice into a new low-extent state.

Such a great (and concerning 😬) workshop! #Climate #Antarctica

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.

We have a new Securing Antarctica's Environmental Future research fellow position (Level A or B) in Melbourne to understand teleconnections between the tropics and Antarctica working closely with researchers Bureau of Meteorology, Australia. Apply at tinyurl.com/mujjat9b by 15 October and come join us in Monash Earth, Atmosphere and Environment 🌏🌪️🍃 !

"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?! 🤣

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. Animation: Planetary Visions/European Space Agency
