“[The IPCC working group 1] projects with high confidence an increase in the variability of the water cycle in most regions of the world and under all emissions scenarios…” “Over the 21st century, the total land area subject […]

Higher global temperatures, resulting from climate change, are expected to increase extreme rainfalls due to increases in the moisture holding capacity of the atmosphere. Higher temperatures are also likely to increase potential evaporation contributing to greater water stress. […]

Australia is experiencing widespread, rapid climate change not seen for thousands of years and may warm by 4℃ or more this century, according to a highly anticipated report by the Intergovernmental Panel on Climate Change (IPCC). The assessment, […]

The Murray-Darling Basin is Australia’s biggest agricultural region, producing almost 40% of the national food supply during the growing season from April to September. It’s filled with criss-crossing rivers, wetlands and lakes farmers rely on for crops, and […]

Some rivers flow all year (perennial), others may flow most of the year or only occasionally (intermittent). This flow period and the intensity and volume of the flow define a river’s flow regime. Understanding the flow regime is […]

To help Australia adapt to climate change and manage the disasters that come with it, the federal government this week pledged A$600 million towards establishing the National Recovery and Resilience Agency, and $210 million for the Australian Climate […]

Imagine, for a moment, a different kind of Australia. One where bushfires on the catastrophic scale of Black Summer happen almost every year. One where 50℃ days in Sydney and Melbourne are common. Where storms and flooding have […]

An international research team has demonstrated that climate change, rather than water and land management, plays a crucial role in river flow at a global level. Climate change is affecting the water balance of our planet: influencing the […]

Climate change has far reaching implications on the hydrologic cycle impacting agricultural productivity, water resources availability, and increasing flood hazard – but understanding how the hydrologic cycle is changing across Australia is challenging. Many hydrometeorological variables are not […]

People living on the east coast of Australia have been experiencing a rare meteorological event. Record-breaking rainfall in some regions, and very heavy and sustained rainfall in others, has led to significant flooding. In different places, this has […]

Public battles between farmers and the environment movement must end, the Commonwealth’s water agency says, warning a unified response is needed to tackle the damaging impacts of climate change in the Murray Darling Basin. A joint study by […]

Australia needs to apply the same science-led approach to climate change as it did to the coronavirus pandemic, the NSW Environment Minister says. Matt Kean, who has clashed with his federal Liberal colleagues during the year, believes Australia […]

A climate watcher has said she is being “blown away” and “in shock” by Australia’s start to summer which is refusing to play by the rules. A climate watcher has said that she is “in shock” at how […]

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 […]
