温室气体的增加预示着高纬度的全球性变暧对北冰洋的冰会产生举足轻重的影响。冰的融化使其厚度及面积减少,冰川间隙加大。有关资料多是潜艇在冰下通过声纳测得的,它们还不足以能证实冰的大面积变薄,要想确定其具体趋势则需要更多的资料。海水与冰的复杂混合使得北冰洋成为全球气候系统的一个重要组成部分。海冰的地理分布及厚度决定着北冰洋与大气的热量、温度和动量交换。气候模式假定大气中CO_2增加会引起极地海冰的明显变化,它反过来又影响海气的相互作用,并对北半球气
The increase in greenhouse gases indicates that global warming at high latitudes will have a pivotal impact on Arctic ice. Ice melting to reduce the thickness and area, glacial gap increased. Most of the information is submarine sonar measured under ice, they are not enough to confirm the large area of ice thinning, in order to determine the specific trends need more information. The complex mix of seawater and ice has made the Arctic Ocean an important part of the global climate system. The geographical distribution and thickness of sea ice determine the exchange of heat, temperature and momentum between the Arctic Ocean and the atmosphere. The climatic model assumes that an increase in CO 2 in the atmosphere causes a significant change in polar sea ice, which in turn affects the interaction of the sea gases and affects the northern hemisphere
