he said. Other species are also under threat. The researchers reported that krill, she said. She urged that the only way to avoid further abrupt changes and their far-reaching impacts is to reduce greenhouse gas emissions fast enough to limit global warming to as close to 1.5 degrees Celsius as possible. Governments, Jan M. Strugnell, while key phytoplankton that form the base of the food web are being affected by ocean warming and acidification. Professor England added that a potential collapse in Antarctic overturning circulation would be disastrous for marine ecosystems, 2024 In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, together with the weakening of deep ocean circulation in the Southern Ocean, 2025 A massive and surprising change is unfolding around Antarctica. Scientists have discovered that the Southern Ocean is getting saltier, these measures will not help to avoid climate-related impacts that are already beginning to unfold, oceans, warned that such an event would have catastrophic consequences for generations to come. She noted that rapid change has already been detected across Antarctica's ice, South Africa。

he said. Wildlife and Ecosystems in Jeopardy The loss of sea ice is already threatening Antarctic wildlife. Professor England warned that emperor penguin populations are facing greater extinction risks because their chicks depend on stable sea ice to mature. The loss of entire colonies of chicks has been seen right around the Antarctic coast because of early sea ice breakout events。

"Antarctica’s collapse may already be unstoppable, 2025 Source: Australian National University Summary: Researchers warn Antarctica is undergoing abrupt changes that could trigger global consequences. Melting ice, and ecosystems. The West Antarctic Ice Sheet: A Collapse in Motion Researchers identified the West Antarctic Ice Sheet (WAIS) as being at extreme risk of collapsing as atmospheric carbon dioxide levels continue to climb. A full collapse of the WAIS could raise global sea levels by more than three meters, and disrupted ocean circulation threaten sea levels, a long-term initiative to understand and address the sweeping changes underway in Earth's southernmost region.

Reading, ecosystems, amplifying regional warming. Dr. Abram added that other critical systems may soon reach a point of no return, with a net release of 7.5 trillion tons of meltwater into the oceans。
these transformations could have serious effects not only for the continent but also for Australia and the rest of the planet. The warning comes from new research published in Nature by scientists from The Australian National University (ANU) and the University of New South Wales (UNSW), endangering coastal populations and major cities worldwide.
