Shameless self-promotion here, but for anyone in Hobart tomorrow looking for a warm dry place to spend their lunch hour, I’m giving a (free!) public talk on Antarctic sea ice loss at TMAG. @utas.edu.au @imas-utas.bsky.social @antarctic.bsky.social

Lunchtime Talks: Dr Will Hobbs, oceanographer & meteorologist | Maritime Museum Tasmania

Join us for the latest in our Lunchtime Talks series, where we'll hear from Dr Will Hobbs, who will talk us through what recent winters are telling us about Antarctica’s future. For almost four decade...

🌡️ 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.

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.

🌀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.

Is this Australia’s climate wake-up call? Official report reveals a hotter, harder future if we don’t act now

The sobering assessment is a national call to action. The sooner Australia mitigates and adapts, the safer we will be.

💪 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.

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

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.
