1/ More than 600km above 🌏, NASA's PACE (standing for Plankton, Aerosol, Cloud, Ecosystem) satellite is in a polar orbit. Covering the globe in about two days, it gathers data on ocean colour, aerosols, and clouds enabling the study of climate change and ocean ecosystems.

🌍 Last week, 140+ Antarctic scientists came together in #Hobart for our ACEAS Research Forum 2025 to share the latest research and insights about the climate risks emerging from #Antarctica and the #SouthernOcean. Read more: antarctic.org.au/aceas-resear...

Hello Hobart! Excited to be visiting, to give a talk at the Institute for Marine and Antarctic Studies, and a keynote at the @ACEAS annual meeting. Should be a great week (and the weather is amazing!) @antarcticsciaus.bsky.social @utas.edu.au

🦐 The humble #krill sits at the heart of Antarctica’s marine ecosystem. But the ABC reports that global krill conservation talks have stalled again at #CCAMLR. 🔗 Read the ABC story by @southernsky.bsky.social here www.abc.net.au/news/2025-11...

🧊 New research reveals an overlooked Antarctic process that may skew sea level rise projections. ☀️ A team led by Dr @fabiobdias.bsky.social (ACEAS/UNSW) found East Antarctica ice shelves melt in summer bursts as sea ice retreats and warm water flows underneath. 🔗 antarctic.org.au/overlooked-m...

🪨 Australia’s climate story is written in stone – and sea 🌊 This ABC Deep Time feature explores how Australia’s landscapes have shifted over millennia, shaped by rising seas and changing climates – told by First Nations voices alongside scientists, linking deep cultural memory with geological time.

🌍 New research shows how fossil fuel emissions translate directly into human and ecological impacts – from extreme heat exposure to coral loss. This is a valuable tool for policy makers and insurers assessing the true costs of fossil fuel developments. 🔗 Read more: www.nature.com/articles/s44...

Recent research shows low sea ice is changing #phytoplankton bloom timing and composition in the Southern Ocean. “Phytoplankton are the ocean’s version of the Amazon rainforest,” says ACEAS lead author Tamara Schlosser from @utas.edu.au. 🔗 Read the news article: antarctic.org.au/microscopic-...

❄️ Fact vs Fiction Q: Has Antarctica’s ice mass rebounded after increasing in recent years? A: Whilst fluctuations have occurred, the continent has lost around 2.5T tonnes of ice since 2002. Our Director @deformedearth.bsky.social (UTAS) explains in AAP FactCheck. 🔗 www.aap.com.au/factcheck/sc...

❄️“In a world of misinformation, it’s critical that government has released an evidence-based assessment.” – ACEAS Director, Prof Matt King @deformedearth.bsky.social @antarcticsciaus.bsky.social @antarctic.bsky.social @utas.edu.au ⬇️Read our story here antarctic.org.au/antarcticsnc...

So very important that the Australian Government has released its evidence-based climate risk assessment. It explains so clearly that climate risks are not far off, but right now and very soon. Risks are not limited, but widespread and, indeed, touch us all. 1/4 www.abc.net.au/news/2025-09...
