  • Colour-shaded map of eastern New South Wales showing modelled near-surface air temperatures. Warm colours (yellow, orange and red) dominate inland areas and the Sydney region, while cooler greens and blues occur along the coast and across the elevated terrain of the Snowy Mountains in the south-west. Weather station locations are marked by labelled circles distributed across the map, with a dense cluster around Sydney. The Tasman Sea appears on the right in pale blue-green shades, and the map focuses solely on the geographic region without axes, title, or legend.

    Slaying the monster of climate change, one reproducible result at a time

    In Greek mythology, Theseus unspooled a ball of string behind himself as he ventured deeper into the dreaded labyrinth of King Minos. After defeating the Minotaur – a terrifying beast that lived within the maze on the island of Crete – the Athenian hero used the string to retrace his steps and escape the labyrinth.…

  • Close-up view of a surface covered in countless small, translucent ice shards or crystals, creating a textured, frosted pattern in pale blue and gray tones. The image fills the frame with no visible horizon or distinct objects, emphasizing the sparkling, granular texture.

    Hail conditions on the move as winter crops face rising risk

    New research led by UNSW suggests that as the climate warms, the conditions that produce hailstorms are drifting towards the poles, leaving winter crops increasingly exposed. A hailstorm can undo a season’s work in minutes. It can strike quickly and unevenly, shredding wheat, bruising fruit and flattening crops, while leaving neighbouring paddocks untouched. In a…

  • Bright sun blazing over a hazy city skyline, with orange and red tones suggesting extreme heat and air pollution.

    Deadly heat stress conditions are already occurring

    Deadly heatwave events are occurring at temperatures and humidity levels previously thought to be survivable, according to a new paper led by 21st Century Weather and featuring a team of international researchers. A study by Professor Sarah Perkins-Kirkpatrick and her collaborators looked at heatwaves that occurred in Mecca (Saudi Arabia) during 2024, Bangkok (Thailand) during…

    Changes to the Arctic and Antarctica will mean fewer short storms, but longer extremes

    A giant rotating tank of water in a laboratory in Canberra is an alternative to supercomputers for the scientists trying to predict the impacts of climate change – and the results are a mix of good and bad news for Australia.  A key challenge facing the world’s researchers is understanding the role of polar amplification…

    Eastern and western Tasmania rely on different weather systems for rainfall, new study shows

    Tasmania’s rainfall is driven by a diverse range of weather systems, with new research revealing how these systems shape seasonal variability across the state. The findings come from a study led by 21st Century Weather researchers based at the University of Tasmania, which examined the contributions of different weather systems to Tasmania’s rainfall. The study…
