The UK is experiencing an "extreme" marine heatwave with ocean temperatures 2C warmer than usual, potentially causing mass-mortality events for marine species. Scientists link this to Europe's recent heat dome and El Niño conditions, warning of significant ecosystem disruption.
A brown skua found dead at Cape Le Grand National Park, Western Australia, has tested positive for avian influenza. Further testing is underway to confirm if it is the H5N1 strain. A second bird, a giant petrel, is also being tested. Officials urge the public not to touch sick or dead birds.
