The Ross Ice Shelf plays a crucial role in stabilizing the Antarctic Ice Sheet by slowing the flow of glaciers and ice streams into the ocean, reducing the rate of sea level rise as a result.

According to data gathered by the US National Snow and Ice Data Center (NSIDC), the Antarctic sea ice extent was 801,548 square miles (2.07 million square km) as of February 15, 2025.

Antarctic sea ice extent has fallen dramatically in recent years – the effects include accelerated ocean warming, faster loss ...

The ocean around Antarctica is rapidly getting saltier at the same time as sea ice is retreating at a record pace. Since 2015 ...

Sea ice in the Antarctic Ocean had been growing for decades, but now, a sudden trend downward could spell serious trouble.

New research into some of Earth’s largest ice sheets has revealed a startling new Antarctic tipping point, and researchers say that it has the potential to be disastrous.

Antarctica could see a doubling of extreme weather events—such as atmospheric rivers—by 2100, with implications for future sea level rise.

International researchers announced the discovery of an over 30-million-year-old lost world beneath the Antarctic ice that may have teemed with rivers, forests, and possibly even palm trees.
