Stoked to share our Australian community’s voice on “impacts of #Antarctic #SeaIce extremes“ published in PNASNexus!

Massive kudos to Ed for spearheading this epic, super multidisciplinary work👏🥳 And so honoured to be a part of it.

Obviously I have skin in this game- being an Australian govt-funded Antarctic scientist and all - but this rolling short-term funding model threatens a world leading concentration of experts at a time when Antarctica is changing faster than govt policy…

Antarctic research jeopardised by 'terminating' funding, scientists say

Australia's ability to conduct strategic, in-depth, and long-term research in Antarctica is being compromised by "terminating" funding models for key programs, scientists warn.

Some (good) personal news - I am so happy to share that today is my first day at Climate Central (as a Climate Scientist).

Ready to move the science and communication of it forward in this crucial moment. Follow our work on climate services at @climatecentral.org (Bluesky) & www.climatecentral.org

Scientists in Japan are looking to publish links between global warming and severe weather within days of such events, rather than months, to raise public awareness about climate change.

When extreme weather hits, Japan scientists will have faster answers on climate links

The Weather Attribution Center will aim to publish concrete links between global warming and extreme weather events within days, rather than months.

今回は何と言っても、オーストラリアの新型砕氷船Nuyinaの処女研究航海。観測能力は本当に文句の付けようがなく、その最初の歴史の一部となれたことは大変な幸運でした。

🌊 Low sea-ice cover means the Denman Marine Voyage #DMV can get to places no humans have been before.

Claire Yung (@scienceanu.bsky.social & @antarcticsciaus.bsky.social) says it allows us to obtain critical data, but is also a reminder of serious and unprecedented changes to Earth’s climate.

Anomalies in sea-ice concentration for March 2025 in the Denman Glacier-Shackleton Ice Shelf region. Anomalies are calculated as the difference between the sea-ice concentration and the 1981-2010 mean sea-ice concentration for that month. (data: NSIDC, source: nilas.org, map: AAPP)

Antarctica's icebergs are famous for their brilliant whites and blues 🧊 Then, there's the startling green, brown, black and even marbled hues - as seen at the Denman Glacier ice front. But how does it happen?
