An international review of IPCC reports since 2001 has found that as the science has improved with each report, a trend has appeared showing climate-related impacts like heatwaves, the collapse of the West Antarctic ice sheet and coral […]

Dryland rivers are inherently variable in terms of their hydrology, geomorphology, and ecology across a range of scales. This variability can make it difficult to disentangle long-term change from natural variability and makes it difficult to assess their […]

An analysis of new climate model projections by Australian researchers from the ARC Centre of Excellence for Climate Extremes shows southwestern Australia and parts of southern Australia will see longer and more intense droughts due to a lack […]

Australia’s complex and extensive inland rivers are among the most hydrologically variable in the world, and yet they are lifelines through dry landscapes that support a large and important agricultural industry and some of our most unique ecosystems. […]

The most recent generation of models of the Coupled Model Intercomparison Project better captures rainfall drivers, extreme heat events, and other facets of regional climate. On the heels of an unprecedented wildfire season, climate is yet again a […]

It has been estimated that as the Earth warms the atmosphere will be able to hold around 7% more moisture for each degree of global warming. As a result, it is expected extreme precipitation events will vary in […]

As the climate changes, past observations may no longer represent the future we’re trying to predict; this could invalidate models calibrated to observed data. Hydrologists have traditionally addressed this problem by looking to past climate variability as a […]

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 […]
