北极海冰创历史新低,2025年3月覆盖1 433万平方公里。 Arctic sea ice hits record low, covering 14.33 million square kilometers in March 2025.

北极海冰在2025年3月达到创纪录的低点,覆盖面积1 433万平方公里,低于2017年的1 441万平方公里。 Arctic sea ice reached a record low in March 2025, covering 14.33 million square kilometers, down from 14.41 million square kilometers in 2017. 这一下降是由于气温变暖和冰层变薄造成的,这种下降继续保持几十年来观察到的冰覆盖率不断下降的趋势。 This decline, attributed to warmer temperatures and thinner ice, continues a trend of decreasing ice coverage observed over decades. 科学家们警告说,这可能预示一个无冰的北极夏季的未来,影响全球气候模式和海洋生态系统。 Scientists warn this could signal a future with ice-free Arctic summers, impacting global climate patterns and marine ecosystems.
