Australia has a long history of bushfires. The 2019-2020 Black Summer was the worst in recorded history. But was that the worst it could get? Read more at The Conversation
A world-leading oceanographer at the University of Tasmania has been awarded an Australian Research Council Australian Laureate Fellowship to develop precision tracking of changes in the Earth’s climate system as it responds to emission reductions. Professor Nathan Bindoff is one of 17 Laureate Fellows announced by the Australian Research Council today, winning a grant of $3,443,000 million over the next five years. Read more at UTAS
If you hear the words "climate change" and you begin to drift away, you're not alone.
It's called "climate fatigue", the idea that the challenge is too big, too difficult to comprehend, too scary so you just switch off.
So how do you communicate the urgency of the climate crisis without overwhelming an audience?
That was best selling Icelandic author, environmental campaigner, and former presidential candidate Andri Snaer Magnason's challenge when he set about writing his book, On Time and Water.
The Southern Ocean, a region critical to Earth’s climate, hosts vast blooms of microscopic ocean plants known as phytoplankton. They form the very basis of the Antarctic food web. Read more at The Conversation
Dr Petra Heil of the Australian Antarctic Division, and Dr Alex Fraser of the Australian Antarctic Program Partnership at the University of Tasmania, are collaborators in the Earth Dynamics Geodetic Explorer (EDGE) proposal led by the Scripps Institution of Oceanography at the University of California, San Diego. Scripps glaciologist Prof Helen Fricker is the Principal investigator for the EDGE satellite mission and a University of Tasmania alumni. Read more at UTAS
They might be the largest animal on the planet but Antarctic blue whales are remarkably tricky to find. That is why when putting together the most up to date snapshot of blue whale distribution, scientists from the Australian Antarctic Division (AAD) had to listen, rather than look. Read more at ABC
Thousands of bus-sized humpback whales are currently on their way to Australian waters. They’ve spent the summer feeding in the cold waters of Antarctica before heading north to breed and calve. Read more at The Conversation
One of 88 women from 19 countries, Ms Salmond's 19-day journey aboard an ice-strengthened expedition ship completed a year-long leadership program with the Homeward Bound project. Read more at ABC
The RV Investigator allows scientists to monitor climate change, map the sea floor and discover new marine species. But a $34 million funding shortfall will see its research operations slashed by a third in the coming years. Read more at ABC
Failure to limit average global temperatures to 2°C above pre-industrial levels by 2100 will likely lead to a ‘regime shift’ in the Weddell Sea, and potentially a tipping point where the 430,000km2 Filchner Ronne Ice Shelf melts rapidly. Read more at COSMO
Scientists are concerned about the impact of a deadly strain of bird flu, which has finally reached mainland Antarctica, leaving Australia as the last continent to be conquered. Read more at the ABC
27 scientists spent the summer in Antarctica to unearth the secrets of the Denman Glacier and better help protect the area vulnerable to climate change. Read more at the ABC
For the third year in a row, sea ice coverage around Antarctica has dropped below 2m sq km – a threshold which before 2022 had not been breached since satellite measurements started in 1979. Read more
If tests are successful, Windracers Ultra UAV will be used for research such as surveying marine ecosystems and studying glaciers. Read more at The Guardian
Emperor penguins are the largest but least prevalent Antarctic penguin species, with scientists estimating a total population of about 600,000. Read more at The Guardian

Climate scientists don’t like surprises. It means our deep understanding of how the climate works isn’t quite as complete as we need. But unfortunately, as climate change worsens, surprises and unprecedented events keep happening. Read more at The Conversation
If we want to understand the future, it’s often useful to look at the past. And even more useful if you use octopus DNA to peer into worlds long gone. Read more at The Conversation
Scientists say numbers of world’s second-largest animal have slowly improved since 1970s whaling ban but sightings in Antarctic feeding grounds are rare. Read more on the Guardian
The ACEAS elephant seal tagging team are aboard the icebreaker that departed this week for Macquarie Island. Once the team arrive, they will spend the next few weeks in relative isolation at Bauer Bay, gathering data on the world’s most mysterious ocean—the Southern Ocean—via elephant seals.

Now, penguin experts say these birds that move like tuxedoed toddlers are showing us the hidden hazards of burning coal and other fossil fuels by the way they march. And as global warming changes the survival-of-the-fittest game at the bottom of the world, one particular species of Antarctic penguin is modelling a poignant lesson for humanity. Read more on CNN
As nations meet in Uruguay to negotiate a new Global Plastics Treaty, marine and forensic scientists publish new results this week that reveal the discovery of synthetic plastic fibres in air, seawater, sediment and sea ice sampled in the Antarctic Weddell Sea. Read more at EurekAlert
Using octopus DNA, octopus scientists have discovered that 125,000 years ago a bunch of Turquet's octopus (Pareledone tuerqueti) travelled from one side of the Antarctic to the other side to have octopedal relations with each other. Read more on the Guardian
This winter has confirmed what scientists had feared — the sea ice around Antarctica is in sharp decline, with experts now concerned it may not recover. Earlier this year, scientists observed an all-time low in the amount of sea ice around the icy continent, following all-time lows in 2016, 2017 and 2022. Usually, the ice has been able to recover in winter, when Antarctica is reliably dark and cold. Read more on the ABC
The health of these moss beds is declining due to changing climate conditions, ozone depletion and heatwaves. Yet our understanding of the problem is limited. Conducting research in Antarctica is difficult. Periods of data collection are short, and there can be years between each research opportunity. Fortunately, new technology offers solutions.

Humans have only recently begun to think about using hydrogen as a source of energy, but bacteria in Antarctica have been doing it for a billion years. We studied 451 different kinds of bacteria from frozen soils in East Antarctica and found most of them live by using hydrogen from the air as a fuel. Read more on the Conversation
Ecologists say sub-Antarctic Macquarie Island is visibly recovering, nine years after it was declared pest-free. Scientists will analyse samples collected on the World Heritage island to better understand other threats, such as climate change. Read more on the ABC
Nitrogen-rich droppings from penguins and seals along the Antarctic Peninsula fuel biodiversity hotspots that stretch several kilometres inland, researchers reveal in a paper published in the journal Current Biology. Read more on Cosmos
For the sixth year in a row, members of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)—part of the Antarctic Treaty System—failed to agree on any new marine protected areas in the fragile Southern Ocean. Read more at Scientific American
The Southern Ocean overturning circulation has ebbed 30% since the 90s, CSIRO scientist claims, leading to higher sea levels and changing weather. Read more on the Guardian
