❄️ A landmark new study has revealed that glaciers on Australia’s remote sub-Antarctic Heard Island are shrinking at an accelerating rate due to rising temperatures and climate change.

Kati Thanda-Lake Eyre last held permanent water in the early Holocene. Will these flooding events be more frequent in a warmer world?

Will they call it a ghetto?

The earliest evidence of high-elevation ice age occupation in Australia - Nature Human Behaviour This study reports on excavations of hearths and stone artefacts from 20,000-year-old deposits at Dargan Shelter, which at an elevation of 1,073 m is believed to be the oldest occupied high-altitude s...

Excited to have been able to contribute to this story of people during the ice age in Australia.

We used 1,000 historical photos to reconstruct Antarctic glaciers before a dramatic collapse Few observations exist from before the 2002 Larsen B Ice Shelf collapse. We’ve now estimated how many billions of tons of glacier ice were lost – and what it means for the future.

In a paper published last year in Scientific Reports, we used nearly 1,000 film photographs of Antarctica from the 1960s to reconstruct exactly what five glaciers were like decades before the Larsen B Ice Shelf collapse.
