Antarctica’s sea ice has reached alarming lows for a second consecutive year, with 2024 seeing less frozen ocean than the same time last year. In September, the sea ice covered 17 million sq km, significantly below the long-term average of 18.4 million sq km. This drop is roughly the size of Britain, France, Germany, and Spain combined. Scientists warn that warmer Southern Ocean temperatures, driven by record global heat, are pushing the Antarctic system into a “new state,” raising serious concerns about the impacts of climate change on our polar regions. Research, data and quotes from the Australian Antarctic Program Partnership, Australian Bureau of Meteorology, and the University of Tasmania.

In today's retrospective, we take a look beneath the Antarctic ice shelves. Last week, several studies provided new insights into the melting processes that are increasingly destabilizing the ice shelves.

💡Did you know? #AntarcticSea Ice Shrinking to Record Low! 🌊 🧊📉Antarctic sea ice is rapidly declining again, marking another worrying milestone after last year's record low. Here are some key highlights: 🔸Ice cover in the #SouthernOcean has shrunk by 1.6 million square kilometers compared to the average – an area equivalent to several European countries. 🔸The trend of shrinking sea ice continues into 2024, following six months of declines in 2023. 🔸By early September, sea ice levels had already dropped below last year’s historic low. 📢Dr. Will Hobbs, physical oceanographer and sea ice researcher for the Australian Antarctic Program Partnership (#AAPP), emphasizes that with global temperatures 1.5°C above pre-industrial levels, the Southern Ocean is struggling to freeze as before. This could have serious consequences, including: 🛑Potential acceleration of #glacier_melting and #ocean_warming. 🛑Disruption of #global_weather systems and vulnerable #wildlife_ecosystems. Recognizing such urgency, our entire team at #UrjanovaC is striving to accelerate the adoption of our #carbon_capture technologies, aiming to #reduce_industrial_emissions that contribute to #global_warming and #sea_ice_loss. We commend the scientific community for their tireless efforts and remain committed to supporting #sustainable solutions for a #low_carbon future. 🛡️Together, we can protect #Antarctica and slow the impacts of #climate_change. 🛡️ Vikram Vishal | ARNAB DUTTA | Piyali Majumder | Koyel Das | Sujit Gurav | Sahil Gurav | Aryaman Mihir Seth | Suhana Karim | Rajeshwaree B | Anwesha Banerjee

" Antarctic ice floes extended further than ever recorded this southern winter, confounding the world’s most-trusted climate models. “It’s not expected,” says Professor John Turner, a climate expert at the British Antarctic Survey. “The world’s best 50 models were run and 95% of them have Antarctic sea ice decreasing over the past 30 years.” The winter ice around the southern continent has been growing relatively constantly since records began in 1979. The US National Snow and Ice Data Centre (NSIDC), which monitors sea ice using satellite data, said this week that the year’s maximum was 1.54m sq km (595,000 sq miles) above the 1981-2010 average. The past three winters have all produced record levels of ice. “Not every location on the Earth is having the same responses to climate changes. The fact that ice in one part of the world is doing one thing and in another part ice is doing another is not surprising. The Earth is large and as the climate changes it is normal to see different things going on,” says Parkinson. " ---Source : https://lnkd.in/gWDV_G3v

Drilling on the edge: Daring ‘James Bond’ mission to drill Antarctic ice cores could reveal future of sea level rise. To understand the vulnarable glaciers holding back meters of sea level rise, climate scientists swoop in to extract ice from Antarctica’s remote and stormy west coast. https://lnkd.in/d3RG8fU4

❄ Sea ice plays a crucial role in our global climate system. It reflects sunlight, regulates temperatures and supports unique but vulnerable ecosystems. However, with climate change accelerating, our sea ice is shrinking at an alarming rate. ❄ A new paper, published last week in Nature Geoscience and led by Alex Bradley (British Antarctic Survey) and Ian Hewitt (University of Oxford) has identified a new tipping point in the way Antarctic ice sheets melt. Seawater, making contact with the underside of the ice sheet, can cause localised melting of the ice - further exacerbated by warming temperatures. This has been described as ‘missing physics’, as current models do not have the ability to simulate melting beneath the ice sheet. The results of this new work in such models could give more reliable estimates as to the speed and extent of melting ice. See the paper here: https://lnkd.in/efXSG9s7 ❄ The project was supported by NERC: Natural Environment Research Council, the PROTECT project and funding from the European Union’s Horizon 2020 research and innovation programme. #makingsciencehappen #expeditionscience #BAS #climate #research #seaice #Antarctica #NERC

While some still hope that new technologies will save us from the consequences of climate change, a new study on the West Antarctic Ice Sheet shows that such convenient solutions are unlikely to work.

Researchers have revealed alarming findings about the rapid disappearance of meteorites from the Antarctic ice sheet due to #globalwarming Led by Harry Zekollari and Veronica Tollenaar, a team of experts from Switzerland and Belgium used a combination of artificial intelligence, satellite observations, and climate model projections to estimate the impact of #risingtemperatures on these extraterrestrial fragments. https://bit.ly/3PTZR11
