Dave Hunt/AAP 2019 was the year Australians confronted the fact that a healthy environment is more than just a pretty waterfall in a national park; a nice extra we can do without. We do not survive without air […]

The field of climate change event attribution research has emerged recently and can provide new insights into Australian climate extremes. When a climate extreme event with notable impacts comes along, a natural question arises – “did anthropogenic climate […]

The issue of whether Australia’s current drought is caused by climate change has been seized on by some media commentators, with debate raging over a remark from eminent scientist Andy Pitman that “there is no link between climate […]

Many studies have shown that conceptual hydrologic models become less reliable as the conditions they aim to simulate deviate further from the calibration conditions. Some attempts to improve model transferability under change have been published, considering options such […]

Sydney and Melbourne face rising threats to their water supplies from climate change as higher temperatures diminish inflows while pushing up demand, according to new research. A paper published by Environment Research Letters shows a “substantially” amplified risk […]

A new study has found that South Australia’s droughts are getting worse, becoming longer and more severe. Professor Simon Beecham, UniSA’s Deputy Vice Chancellor: Research and Innovation, led the study and drew on data from his Goyder Institute […]

Farmers in Mallee Hill and Mount Short in the state’s south have run out of water after months of drought. Two areas of Western Australia have been declared “water deficient” and will have supplies trucked in by the […]

General insurers have lost no time in calling on the re-elected Morrison government to put a “greater focus” on natural disaster mitigation following the Coalition’s shock win in Saturday’s federal election. In a statement congratulating Prime Minister Scott […]

Humans have contributed to increased global risks of drought for more than a century, scientists say, in findings that also point to “severe” consequences ahead with climate change. The research by US-based scientists and published in Nature journal […]

In predicting the trajectory of future climate, water and ecosystems, we can no longer ignore the many ways in which human feedbacks modify our natural systems. The 5th national OzEWEX workshop explored how well we understand stores and […]

As the planet warms, subtropical regions of the Southern Hemisphere, including parts of southern Australia and southern Africa, are drying. These trends include major drought events such as Cape Town’s “Day Zero” in 2018. Climate projections suggest this […]

The El Niño–Southern Oscillation (ENSO) is the dominant and most consequential climate variation on the planet. Answering the question of how ENSO may change under greenhouse warming has been plagued for decades by a persistent lack of inter-model […]

New research in Nature Climate Change suggests droughts may not increase as a result of climate change. This finding resulted from researchers investigating an apparent climate model contradiction that saw climate change projections of the 21st Century produce […]

Water is essential for life. It shapes where and how we live, determines the availability of food and other services that underpin human well-being and is crucial for healthy natural ecosystems. Yet in Australia and globally the water […]

It has been well established that rising temperatures are increasing precipitation extremes. It is natural to hence assume that the risk of flooding will also increase. However, contrary to this popular belief most published literature finds more evidence […]

Australia is facing more severe floods and droughts as rainfall patterns diminish over the past three decades, a new report has warned. Co-author Professor Will Steffen from the Climate Council said the report shows an intensification of drought and […]

Two years ago we were celebrating just about the best year for farmers ever. Now many farmers – particularly in New South Wales and southern Queensland – are in the grip of drought. It underlines just how variable […]

It’s not about more money for farmers. It’s about long-term settings for a changing climate – and taking the politics out of it Central to the Australian meaning of drought is the idea of a rainfall deficiency, a […]

Australia’s rainfall events are already becoming more intense with climate change, raising the risks of flashflooding and potentially exceeding the nation’s engineering codes, a new study finds. While it’s long been understood the atmosphere holds about 6.5 per […]

Currently, flood risk management practitioners in Australia mostly use event-based models (simulating a single flood event in isolation) as opposed to continuous models (simulating runoff dynamically over time). However, there is a commonly held belief in the hydrology […]
