Antarctica hangs in the balance. Five cities have the chance of securing the future of this fragile continent.
After record-breaking amounts of sea ice in Antartica, this year we're seeing record lows.
The shock decision to close Australia's year-round research station at Macquarie Island will make monitoring Antarctica and the Southern Ocean harder, and will force Tasmania to get creative.
The first signs that humans were warming the climate appeared much earlier in the northern hemisphere - way back in the 1830s. But now the trend is emerging all over the globe.
If we accept that 2 degrees warming is dangerous this century, we have to accept it is dangerous beyond.
Buried beneath kilometres-thick slabs of ice are rivers and huge lakes - some of which are teeming with microbes that thrive in a world without light or oxygen.
Australia and China both have a keen interest in the frozen continent. And while they don't agree on everything, there is great scope for scientific collaboration.
It's one of the remotest places on Earth and yet is still claimed by six nations – including Australia.
What the Montreal Protocol has done for the ozone hole threat other international accords could do for climate change – if we all agree.
Vote Leave claims the EU is the slowest growing area in the world. Are they right?
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.
What gaps have the CSIRO cuts left in climate research?
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.
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.
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.
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 neutrinos detected deep under the Antarctic ice may have originated from a distant quasar on the edge of the visible universe.
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.
As the world warms, Antarctica's melting ice will likely reach the point of no return.
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.
