Shackleton's infamous ship 'Endurance clearly had several structural deficiencies,' new analysis reveals Ernest Shackleton's ship, the Endurance, infamously sank in Antarctica — and now a new study finds that it had known flaws.

The infamous ship Endurance, which sank in #Antarctica in 1915, wasn't as well built for a polar voyage as previously thought — and its owner was likely aware of its shortcomings via @livescience.com

Atmospheric chaos has sent temperatures soaring in Antarctica Stratospheric temperatures in Antarctica are spiking, which could see strange weather unfold across the southern hemisphere in the coming months

🧊Our researchers have just finished analysing ancient Antarctic ice spanning 1.2 million years of climate history!

The Beyond EPICA project extends the ice core climate record by 400,000 years, helping us to understand long-term climate patterns and improve future predictions.

Geoengineering is not going to save the poles from climate change A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both

With emissions still rising 📈 and the catastrophic consequences 🔥 becoming ever clearer, geoengineering is getting ever more tempting 🧪

But a review has concluded that the main methods proposed to save polar ice 🧊 are not doable or won't work

Polar stereographic map showing Antarctic sea ice concentration anomalies for August 2025 compared to a 1981-2010 average. Data is from https://nsidc.org/data/g02202/versions/5.

The rate of #Antarctic sea ice extent growth has increased over the last few weeks as we approach this year's annual maximum (austral winter). No new records will be set this year, thought current ice concentration remains quite low in several regions.

📉 Antarctic sea ice has hit record lows between 2022 and 2025.

A new summary on the Antarctic Environments Portal explores the causes, consequences, and signs of a lasting regime shift in the sea ice system.

Arctic glaciers face ‘terminal’ decline as microbes accelerate ice melt Scientists in Svalbard in race to study polar microbes as global heating threatens fragile glacial ecosystems “It felt really scary … like being in the middle of a burning city during a night raid.” Dr Arwyn Edwards is not describing urban warfare but a recent hot and foggy day on a Svalbard glacier, where record-breaking summer heat turned his workplace into a cascade of meltwater and falling rocks. Edwards is a leading researcher in glacier ecology – the study of life forms that live on, within and around glaciers and ice sheets. Over two decades of polar research, he has always felt “relaxed and at home” on ice. But the accelerating climate breakdown is beginning to erode that sense of security. Continue reading...

Arctic glaciers face ‘terminal’ decline as microbes accelerate ice melt

Map showing the Antarctic anomaly of the July 2025 sea-ice concentration relative to the mean July ice concentration in 1981-2010. Especially, the sea ice around the Antarctic Peninsula, and in the King Haakon VII sea, shows large areas of negative anomaly (red colour). Source data is OSI SAF sea-ice concentration CDR v3.0.

The line graph displays the monthly sea-ice extent in the Antarctic for July from 1979 to 2025. In 2025, the July extent ranked as the third lowest on record. Source data is OSI SAF sea-ice index.

Disregarding the extreme and record-low sea-ice extent in Antarctic the last two years, this year's July extent is exceptionally low, ranking as the 3rd lowest on record.

The July extent over the last four years differs significantly from that of the previous four decades.

Sea ice controls net ocean uptake of carbon dioxide by regulating wintertime stratification - Communications Earth & Environment Interannual variability of ocean uptake of carbon dioxide is governed by winter sea ice cover, according to analysis of carbonate chemistry observations along the West Antarctic Peninsula.

📢 New paper alert! 📢

New insight into how sea ice controls the ocean uptake of carbon dioxide around Antarctica, obtained from the unique year-round Rothera Time Series.

Last month was the 2nd hottest May on record globally (after just last year and with 2020 in 3rd). Some of the largest warm anomalies were in the Middle East, and it was notably cooler over India.
