    Local extremes, global impacts: Attribution for Loss & Damage

    In recent years, the world has been grappling with the growing impacts of climate change, from devastating heatwaves to floods and droughts. Behind the scenes, work has been continuing to determine how we can fairly and accurately support affected communities and countries via the mechanisms of Loss & Damage and impact attribution.  A significant outcome

  • Seasons & regions key to linking El Niño, La Niña & rainfall

    New research conducted using machine learning has highlighted the importance of focusing on specific seasons and regions when using major modes of climate variability to predict rainfall.  Large-scale modes of climate variability, such as the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), are often identified in advance by major weather organisations around

    Why was 2022 in Australia so wet, and will it happen again?

    Slow-moving systems of low pressure, high levels of atmospheric moisture and a perfect storm of La Niña, the Indian Ocean Dipole and the Southern Annular Mode caused Australia’s devastating 2022 floods, but more research is needed to understand the role of climate change in future heavy rainfall. Eastern Australia experienced record-breaking rainfall and flooding during

    Humid heat is exceeding human tolerance & causing mass mortality

    Critical physiological limits to human heat tolerance are drawing ever closer, highlighting the urgent need to limit further climate warming and emphasising the adaptation challenge ahead. Writing in the journal Nature Climate Change, 21st Century Weather researchers and their collaborators at institutions around the world offered a stark reminder that the hottest boreal summer on
