  • A person uses a hose to control a small brush fire beside a rural road. Smoke rises from dry grass and underbrush among trees on the left. Two vehicles are parked nearby, one equipped with a hose reel, indicating firefighting activity. The sky is clear with haze from the smoke, and the surrounding vegetation appears dry.

    Deforestation and cropland expansion driving stronger heatwaves

    New research has revealed that land clearing and rapid development can sharply intensify heatwaves beyond the impacts of global warming, offering important lessons for many countries already grappling with record-breaking heat. The study, published in the Nature journal Communications Earth & Environment, analysed Africa as a case study, but found universal physical mechanisms that apply…

    Ocean fronts revealed as key players in Earth’s carbon cycle

    Narrow bands covering just over one-third of the world’s seas are responsible for absorbing nearly three-quarters of the carbon dioxide that oceans pull from the atmosphere, new research shows. The PhD study published in Nature Climate Change reveals ocean fronts play a far larger role in regulating Earth’s carbon cycle than previously understood. Ocean fronts are boundaries…

  • A wildfire burns through dry vegetation, with intense flames engulfing bushes and trees. Thick smoke rises into the sky, obscuring the background and emphasizing the fire’s severity. The landscape appears parched, suggesting rapid fire spread and environmental vulnerability.

    Climate change made Australian heatwave five times more likely

    Previously expected just four times per century, heat at the level recently experienced by Australia is now likely every five years, and will happen every two years without much stronger action to reduce emissions. Human-induced climate change made the intense early January heatwave in Australia five times more likely, according to a new analysis by…

    Doldrum days: New study reveals calm seas are a driver of coral bleaching

    Becalmed in the doldrums. Have you ever heard that old nautical expression? It’s a throwback to the times of Treasure Island and Robinson Crusoe.  Hundreds of years ago, the prolonged absence of wind in the tropical ocean could spell disaster for sailing ships and their crews, who rapidly ran out of drinking water as they…
