How has the growing inclination among some commentators to interpret Antarctica through a security lens reshaped the policy landscape? And is the security narrative itself a threat to Antarctic stability? Discover more with our Antarctic governance experts: tinyurl.com/58vxdt5c

Is the security narrative itself a threat to Antarctic stability?

After more than six decades of peace on the continent, Australia must flex its diplomatic muscle to maintain the status quo.

"Rain, once rare in Antarctica, is becoming a force capable of reshaping life on the peninsula. Limiting warming to below 1.5°C won’t prevent these changes entirely. But it could slow how quickly rainfall transforms the frozen continent." —@iceybethan.bsky.social theconversation.com/rain-is-comi...

Rain is coming to Antarctica – here’s how it will change the frozen continent

In the Antarctic Peninsula, precipitation is increasingly falling as rain rather than snow, with consequences for glaciers, penguins and even scientists.

1️⃣ "Antarctica might seem a long way away, but really the changes that happen there have consequences for everyone on the planet." — Nerilie Abram, AAD Chief Scientist, ABC Radio 🌊 Rising seas are a planetary impact of global heating. The contribution of melting ice in Antarctica is growing. 🎞️ NASA

2️⃣ But it's much more than sea-level rise. " #Antarctica has long been seen as a remote, unchanging environment. Not any more. The ice-covered continent and the surrounding Southern Ocean are undergoing abrupt and alarming changes" — @aunz.theconversation.com ▶️ theconversation.com/from-sea-ice...

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.
