New research published today in Science Magazine has used 🐙octopus DNA🧬to discover that the West Antarctic Ice Sheet likely collapsed during the Last Interglacial period - when global temperatures were similar to today.

#COP28 is our moment to make change.

To protect #Antarctica and our future, world leaders must agree to phase out fossil fuels and limit warming to 1.5°C.

What causes the bumps and wiggles in time series of Antarctic ice-mass change, and how do they relate to large-scale climate modes and ice sheet trends?
That's what we look at in our new paper in Nature Geoscience with Kewei Lyu Xuebin Zhang

It’s not good news at all, but Kaitlin reminds us that even if melting in the Amundsen Sea is unavoidable, it isn’t a reason to give up on climate action.

Yesterday I was interviewed for ABC News radio about the recent record low in Antarctic sea ice extent, along with Ariaan Purich. abc.net.au/listen/program…

On September 10, Antarctic sea ice likely reached its annual maximum extent of 16.96 million square kilometers (6.55 million square miles). This the lowest sea ice maximum in the 1979 to 2023 sea ice record by a wide margin. bit.ly/3rqxa2y

'We have an indication that the underlying processes controlling Antarctic sea ice coverage may have altered, and more work is needed to understand how both the atmosphere and ocean are driving sea ice changes.' — Ariaan Purich & Ed Doddridge in Communications Earth & Environment

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.

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.

Earlier this year, #Antarctic sea ice hit a record minimum of 1.77 million square kilometres, 36% below the 1979-2022 average for the summer minimum. Worryingly, low Antarctic sea ice may be the “new abnormal”, according to Ariaan Purich
