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.

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…
