Antarctica, the world’s most remote, harsh and pristine continent, is not free from marine pollution. Where human activity goes, plastic debris inevitably follows. Read more at The Conversation.

Over the past week, more than 450 researchers gathered in Hobart for the inaugural Australian Antarctic Research Conference — the first such event in more than a decade.
Early career researchers have issued a statement, warning urgent action is needed to prevent catastrophic sea level rise around the world. Read more at ABC.

Australia has described the outcome of a meeting between members of the Commission for the Conservation of Antarctic Marine Living Resources as a "backwards step". Attendees said Russia and China vetoed all proposed measures, including one to renew existing krill management measures. Read more at ABC News

Last year Antarctica’s sea ice was 1.6m sq km below average – the size of Britain, France, Germany and Spain combined. This week it had even less than that. Read more at The Guardian

The Southern Ocean encircling Antarctica is the world’s largest feeding ground for baleen whales – species like humpbacks that filter tiny organisms from seawater for food. In the 20th century, whalers killed roughly 2 million large whales in the Southern Ocean. Some populations, like the Antarctic blue whale, were reduced by more than 99% and have been struggling to recover, even though most nations ended commercial whaling in the mid-1980s.

Previous estimates of ice shelf loss come from satellite measurements, which captured ice shelves gradually thinning in recent years. We tracked how much extra ice had been lost as icebergs calve away from the retreating edge of the continent. We found Antarctica’s ice shelves have lost twice as much mass as previous studies suggested. Read more on The Conversation

The temperature above the east Antarctic coastline warmed by about 50 degrees Celsius in a week earlier in July. The event, called a Sudden Stratospheric Warming has the potential to impact Australia's weather through August and possibly well into spring. Read more at ABC

It is often said AI will take the jobs humans should be doing — but in this case, the human researchers are happy enough to pass on the job of scanning thousands of hours of recordings made deep in the Southern Ocean, freeing them up for the pursuit of scientific breakthroughs. Read more at the ABC

In 1968, an aircraft flew over the Larsen B ice shelf in Antarctica. More than six decades later, photos taken on that flight have been used to create a 3D model of the region's melting glaciers. Read more at ABC

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.

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
