# A new report by the Food and Agriculture Organisation and the World Meteorological Organisation warns that extreme heat is threatening global food supplies, impacting over a billion people. The report highlights how heatwaves are affecting crops, livestock, fisheries and forests, while also putting agricultural workers at serious risk. In oceans, rising temperatures are lowering oxygen levels, with 91-percent of the global ocean experiencing at least one marine heatwave in 2024. The organisations are calling for urgent adaptation measures, including heat-resilient crops, early warning systems and access to financial support.
