欧盟哥白尼海洋服务周三发布的一份新报告称，随着欧洲海域海洋热浪达到创纪录水平，北极正在经历快速变化。
The Arctic is undergoing rapid changes as marine heat waves reach record levels in European seas, according to a new report released on Wednesday by the European Union's Copernicus Marine Service.
报告指出，全球海洋温度持续上升，正在给世界各地的海域带来显著变化，并对海洋生态系统、沿海社区和经济产生重大影响。报告将北极列为变化最剧烈的地区之一。
Rising ocean temperatures are driving significant changes across the world's seas, with consequences for marine ecosystems, coastal communities and economies, according to the report. The report identified the Arctic as one of the regions experiencing the sharpest changes.
报告显示，1979年至2025年间，北极海冰范围每十年减少约49万平方公里，这一面积几乎相当于西班牙的国土面积。
Arctic sea ice extent declined by about 490,000 square kilometers per decade between 1979 and 2025, an area nearly the size of Spain, according to the report.
报告称，海冰减少导致风浪活动增强，使约60%的北极沿海基础设施面临侵蚀和海平面上升的威胁。报告还强调了欧洲各区域海域异常高温的情况。
The decline in sea ice has contributed to increased wind and wave activity, leaving around 60% of Arctic coastal infrastructure vulnerable to erosion and rising sea levels, it said. The report also highlighted exceptionally high temperatures in European regional seas.
地中海和黑海在2024年经历了创纪录的海洋热浪，气温比正常水平高出4.6摄氏度（40.2华氏度）以上。
The Mediterranean and Black Sea experienced record marine heat waves in 2024, with temperatures more than 4.6C (40.2F) above normal.
全球海平面也持续上升，自2012年以来，平均上升速率达到每年约4.2毫米。
Global sea levels have also continued to rise, with the average rate reaching about 4.2 millimeters per year since 2012.
