UNSW experts are available to comment on the recently announced third La Niña in as many years.

By following moisture from the oceans to the land, researchers worked out exactly how three oceans conspire to deliver deluges of rain to eastern Australia.

To look inside a stalagmite is to look back in time tens of thousands of years to see how the Earth’s climate patterns have shaped the world we live in today.

Climate change and urbanisation are set to threaten groundwater drinking water quality, new research from UNSW Sydney shows.

Global water supplies are shrinking, even as rainfall is rising. The culprit? The drying of soils due to climate change.

A global analysis of rainfall and rivers by UNSW engineers has discovered a growing pattern of intense flooding in urban areas coupled with drier soils in rural and farming areas.

A rise in global temperatures of 2 degrees Celsius is likely to bring more extreme rainstorms to many parts of Australia even as other areas experience severe droughts, new research shows.

Cities face harsher, more concentrated rainfall as climate change not only intensifies storms, but draws them into narrower bands of more intense downpours, UNSW engineers have found.

Stalagmites preserve a history of past climate and UNSW research has shown that there’s a correlation between periods of wet and dry and human migration, write Andy Baker and Bryce Kelly

Thirty-year weather records from 79 locations across Australia reveal peak downpours during storms are intensifying at warmer temperatures, leading to greater flash flood risks.
