Mapping tipping risks from Antarctic ice basins under global warming - Nature Climate Change Climate change threatens the future of the Antarctic Ice Sheet. Here the authors show that individual drainage basins have different thresholds and loss patterns, suggesting the need to consider the d...

Antarctica isn’t one big tipping point.

New research maps 18 separate ice basins, each with its own threshold. Some in West Antarctica may tip at just ~1–2C warming (i.e close to today’s levels).

Cross the line, and you commit to m’s of sea-level rise over centuries

Emergent climate change signals within Antarctic sea ice and associated ecosystems - Nature Climate Change The authors model the emergence of climate-driven changes in Antarctic sea ice, phytoplankton, krill, fish and penguins. They show earlier emergence for higher trophic levels, as well as highly season...

🌊 Climate change in Antarctica is anything but uniform.

Regional hotspots. Seasonal reversals. Early biological signals.

The story is more than “less ice = collapse”.

Complex, uneven, and already unfolding.

The Arctic overturning circulation: transformations, pathways and timescales Abstract. The Arctic is the northernmost terminus of the Atlantic Meridional Overturning Circulation and is an important source of the densest waters feeding its lower limb. However, relatively little...

🌊Where and how is dense water in the Arctic formed? In our new paper, we decompose the Arctic overturning circulation (ArMOC), the northernmost part of the AMOC. Check it out 🔽

Today, on the International Day of Women and Girls in Science, we celebrate women in polar research! 🐧🧊

Our AWI photographer Esther Horvath documents in her work life and research in the Arctic and Antarctic. In her TEDx Talk, she offers shines a light on the women scientists.

A Nordic Perspective on AMOC Tipping This report is the outcome of the Nordic Council of Minister’s sponsored workshop arranged in October 21-24, 2025 in Helsinki and Rovaniemi, Finland as part of Finland’s council presidency theme resil...

Just out today: The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the risk of Atlantic Meridional Overturning Circulation (#AMOC) shutdown. 🌊
Conclusion: it's "a serious risk which requires a dedicated risk management framework".

Dusting off the iron hypothesis Nature Geoscience - Erosion by the West Antarctic Ice Sheet can supply iron to the Southern Ocean, with iron solubility as important as iron quantity in shaping ocean productivity and carbon...

🌊 Boosting iron supply in the anaemic Southern Ocean enhances phytoplankton blooms and the ocean’s uptake of atmospheric carbon dioxide.

🧊 'News & Views' @natgeosci.nature.com by Dr Marion Fourquez @utas.edu.au examines a new perspective on where the iron came from in the past.

1️⃣ Antarctic sea ice during winter didn’t use to change very much from year to year. But in recent winters, the extent of ice has crashed to unusually low levels. Which begs the question: what controls how much sea ice can form in winter?

Global trends in ocean fronts and impacts on the air–sea CO2 flux and chlorophyll concentrations - Nature Climate Change Changes in ocean fronts could impact biological productivity and carbon exchange. By analysing satellite and reanalysis data, the authors identify areas with active frontal activity and rapid change i...

🌊 Where the ocean mixes, carbon follows.

2003–2024 satellite + reanalysis data show that ocean fronts host 72% of global CO2 uptake and strongly regulate primary production via enhanced mixing and nutrient supply.

The Arctic’s ‘last ice area’ is showing signs of weakness Mission to Canada’s Queen Elizabeth Islands reveals degradation of a sea ice haven

Plugged with the world’s oldest and thickest sea ice, the fjords of the Queen Elizabeth Islands have long been impenetrable to icebreaker ships.

But even here, in a place where climate models predict ice will persist the longest, global warming is taking its toll. https://scim.ag/4qNgPxW

Waiting for 2025 to end.

Whoa incredibly exciting! It would be lovely if a snap photo of the sunrise from the research cruise could be taken. It’s quite frustrating that we didn’t catch it last year :(

You cannot put the wind in a bag: How we learned to see nature The award-winning nature writer, Robert Macfarlane, talks with Big Think about how to reacquaint ourselves with the rivers in our lives.

A short article invites mindfulness about our modern relationship with nature, echoing the concept of the 'standing reserve' brought up by German philosopher Martin Heidegger.

New paper on ocean mercury cycling! 🌊🧪

Mercury is toxic to marine life 🪱🐟🐋 and accumulates up the food chain. We find mercury is efficiently buried in shallow shelf environments, with implications for the impact of mercury in seawater globally.

Only came across his work yesterday at the Rhodes House Open Day… Quite an article to read.

The score that plays while Mon delivers her speech is the same score that plays as Maarva delivers her posthumous speech in the ANDOR Season 1 finale. A perfect touch.

Music to my ears!

'On 10 May, an uncontrolled reentry will take place of the so-called Cosmos-482 descent craft, a Soviet Venera landing capsule that launched 53 years ago... The landing module could reach the surface of Earth in one piece instead of breaking and burning up. '
