    Deadly, record-breaking heatwaves locked in for 1,000 years, even under net zero pathways

    We must prepare for a future of frequent, deadly heatwaves, which will worsen in severity the longer it takes to reach net zero, new research has shown. Researchers working at the ARC Centre of Excellence for 21st Century Weather and Australia’s national science agency CSIRO used climate modelling and supercomputers to learn how heatwaves will

    From the tropics to the pole: How El Niño touches Antarctica

    A team of Australian climate scientists has explored how weather patterns in the tropical Pacific Ocean can influence the chemistry of snow falling thousands of kilometres away in Antarctica. Working with an ice core drilled at Mount Brown South in East Antarctica, the researchers studied traces of sea salt preserved in layers of snow and

    Strategic wind farms: How to balance weather resources & energy demand

    Carefully choosing the location of wind farms could help to balance electricity supply and demand during hot and cold days in southeast Australia, but more research is needed to better understand the complex relationship between weather, wind and energy. Together with hydroelectricity and solar, wind power is becoming an important source of renewable energy as

    The Earth is at its warmest for 125,000 years, but time remains to prevent total catastrophe

    The 2025 State of the Climate Report has been released, indicating that 22 of the Earth’s 35 vital signs are being pushed to critical levels, as the planet reaches its hottest temperature in the last 125,000 years. Warming is accelerating, the report highlights, while ocean heat content, the volume of tree cover lost to fire
