'Extreme' marine heatwave expected for parts of UK with risk to sea life

A marine heatwave could reach 'extreme' levels around parts of the UK this week, according to the Met Office, with sea temperatures up to 4-5°C above average. Fueled by heat domes and long-term climate change, it threatens seagrasses, shellfish, and other marine life. Scientists, including Dr Zoe Jacobs of the National Oceanography Centre, fear serious ecological impacts. Fishing communities report declining traditional fish catches and rising numbers of warm-water species like octopus.
