A warming Earth could see invading species arrive in Antarctica via the floating "taxi service" of the sea. That could be a threat to the southern continent's delicate ecosystem.

New mapping shows how Antarctica's huge Totten Glacier has retreated far inland, raising sea levels by more than a metre. Rising temperatures could trigger it to do so again.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.
Bureau of Meteorology
Atmospheric carbon dioxide measurements at Tasmania's Cape Grim and Antarctica's Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
The past century hasn’t seen the worst drought that Australia’s climate can throw at us.

A new millennium-long record reveals that Australia has suffered longer droughts and wet periods than those recorded in the past century's weather observations.
Research expeditions, like this one to Antarctica, don’t have to rely on governments for funding.

In an atmosphere of declining government funding for science, researchers can drum up excitement and funding in other ways, just as they did in Edwardian times.
A burst of ghostly neutrinos may have been generated by a quasar like this.

Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
Where the ice meets the sea: Antarctica’s ice shelves play a key role in how fast ice sheets melt.

Antarctica's blue whales all feed in the same place. But a new genetic analysis suggests they are actually three separate populations that breed in different parts of the globe.
Million-year-old ice likely lies more than 3km below Antarctica’s surface.

The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
A portion of the East Antarctic Ice Sheet, called Wilkes Land, flowing into the ocean.

A cubic kilometer of clear, stable ice could help physicists answer big questions about cosmic rays and neutrinos. Hardy scientists collect data via a unique telescope at the frozen bottom of the world.
Antarctica is vital to the planet’s climate system.

If we're going to mine asteroids, then we need an international treaty to prevent it becoming a wild west. Thankfully we can look to Antarctica to see how such a treaty might work.
