Rare phenomenon could disrupt Australia’s weather for months Temperatures above Antarctica have risen by 30C, in a rare event that could potentially flip Australia's spring weather for months.

🌡️ But right now, something quite rare is happening. The stratospheric temperature above Antarctica has climbed more than 30°C in the past week. While weather patterns across Australia could be disrupted, there's one positive: the size of the ozone hole reduces.

▶️ www.abc.net.au/news/2025-09...

🌀The stratospheric polar vortex is a belt of high-speed cyclonic winds around 12-20km high over the poles. When temperatures in the stratosphere – which contains the ozone layer – start rising in the southern spring, the ozone hole over the Antarctic grows.

💪 A superpower of the Southern Ocean is taking up heat and carbon from humans and slowing the rate of global warming, by exchanging heat and carbon between the atmosphere and the deep ocean.

🔄 The freeze-and-melt cycle of sea ice drives this exchange by changing water density and acting as a pump.

Polar 'geoengineering' won't fix climate warming, study finds Proposed "geoengineering" projects designed to reduce the impacts of global warming in polar regions would be ineffective, extremely costly and environmentally dangerous, researchers have warned.

From sea ice to ocean currents, Antarctica is now undergoing abrupt changes – and we’ll all feel them The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.

2️⃣ But it's much more than sea-level rise.
