Ocean heat hits record high for June, experts warn of extreme summer

European scientists are warning of dangerous consequences after ocean surface temperatures reached a record high for June. The spike raises fears of another burst of extreme heat this summer. On 21 June, temperatures outside the polar regions surpassed the extraordinary highs recorded at the same time in 2023 and 2024, according to the Copernicus Climate Change Service. The data, released on Wednesday, shows the ocean is absorbing more heat than ever before. This warming can disrupt weather patterns, speed up global climate change, and harm marine life. Warmer waters also fuel stronger storms and can worsen heatwaves on land. Scientists are closely monitoring the situation as summer progresses.
