温度不断升高,北极持续变化。北冰洋到2030年夏季可能无海冰!在秋季和冬季的几个月中,北极海冰稳步扩展,直至达到最大范围;一般在3月,海冰从某个地方开始减少,通常在9月减到最小。近些年,由于全球气候变暖,专家担忧,北冰洋到2030年夏季可能无海冰。造成海冰范围缩小背后的“推手”是燃烧化石燃料导致的气温升高,但自然现象的相互作用也加剧了这些变化。比如2007年,夏季的海冰范围减小到历史最低,这不仅仅是较高温度造成的,还有一个高气压系统起了作用。
The temperature is constantly rising, the North Pole continues to change. Arctic Ocean may not have sea ice in the summer of 2030! During the autumn and winter months, Arctic sea ice has steadily expanded until it reaches its maximum extent. Generally, sea ice will decrease from somewhere in March, usually in September To the minimum. In recent years, due to global warming, experts worry that the Arctic ocean may have no sea ice by the summer of 2030. The “pusher” behind the shrinking sea-ice range is the temperature rise caused by the burning of fossil fuels, but the interplay of natural phenomena exacerbates these changes. For example, in 2007, the sea ice range in summer was reduced to a record low, not only because of higher temperatures, but also to a high-pressure system.
