Can next week's special meeting in Chile break the deadlock over East Antarctica's marine park proposal?

Amid the challenges of climate change, resource extraction and pollution, the survival of species and ecosystems depends on setting aside protected areas. But plans to establish marine protected areas in East Antarctica have stalled.

Antarctic tipping points: the irreversible changes to come if we fail to keep warming below 2℃

The slow-down of the Southern Ocean circulation, a dramatic drop in the extent of sea ice and unprecedented heatwaves are all raising concerns that Antarctica may be approaching tipping points.

Slowing deep Southern Ocean current may be linked to natural climate cycle – but that's no reason to stop worrying about melting Antarctic ice

Our new research in the Antarctic suggests that the vital layer of cold water on the sea bed, which circulates the globe and influences the ocean’s ability to continue absorbing much of the rise in atmospheric heat and greenhouse gas emissions, is heating up and shrinking.

The church at the end of the world – photo essay

Perched atop a scree hill north of the village, a Russian Orthodox church keeps watch over the Antarctic outpost Villa Las Estrellas. It was built in 2002 from wood shipped from the Siberian city of Altay and its bells were brought from Vladimir, a city east of Moscow

Antarctic sea ice hits another record low: Natural fluctuation or sign of climate change?

Antarctica's sea ice is now reforming as the continent moves deeper into the austral winter, but it's currently the smallest it has ever been for this time of year on record. This blip in the Antarctic pulse is the latest in a string of record lows that is being watched…

Deep ocean currents in Antarctica are slowing earlier than predicted

Antarctica drives a network of ocean currents that redistributes heat, carbon, and nutrients around the globe. There are signs this circulation is slowing down decades earlier than predicted, with profound consequences for the earth’s climate, sea level, and marine life.

Antarctic currents supplying 40% of world's deep ocean with nutrients and oxygen slowing dramatically

Deep ocean currents around Antarctica that are vital to marine life have slowed by 30% since the 1990s and could soon grind to a complete halt, a new study finds.

Antarctic alarm bells: observations reveal deep ocean currents are slowing earlier than predicted

Antarctica sets the stage for the world’s greatest waterfall. The action takes place beneath the surface of the ocean. Here, trillions of tonnes of cold, dense, oxygen-rich water cascade off the continental shelf and sink to great depths. This Antarctic “bottom water” then spreads north along the sea floor in…
