How Antarctic ice melt can be a tipping point for the whole planet’s climate

The climate secrets contained in an ancient tree that lived through abrupt global change reveal how Antarctica can trigger rapid warming in the north by dumping cold water into the Southern Ocean.
The analysis of large amounts of ice from Antarctica’s Taylor Valley has helped scientists to tease apart the natural and human-made sources of the potent greenhouse gas methane. Hinrich Schaefer

Antarctic ice reveals that fossil fuel extraction leaks more methane than thought

Analysis of 12,000-year-old Antarctic ice reveals that methane leaks from fossil fuel extraction play a larger role than previously thought.
The authors have collaborated on an Antarctic research project, investigating tiny ice crystals and their role in climate. Gabby O'Connor's Studio Antarctica/Johanna Mechem

When artists get involved in research, science benefits

When artists and scientists get together, they fuel each other's creativity and inquiry.

Cows in Antarctica? How one expedition milked them for all their worth

What would possess an Antarctic expedition to take dairy cows to the icy continent? Back in 1933, Admiral Byrd did so for reasons of image-making, publicity and territorial ambition.

Don’t worry about the huge Antarctic iceberg – worry about the glaciers behind it

A huge iceberg is set to break free from Antarctica. While the iceberg isn't hugely concerning, it could herald the breakup of the entire Larsen C ice shelf, which could trigger more sea-level rise.

The winners and losers of Antarctica’s great thaw

Climate change is set to expand Antarctica's ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.

Volcanoes under the ice: melting Antarctic ice could fight climate change

Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
