But the lowest summer ice cap on record put sea ice far north of the outer continental shelf , the shallow , life - rich shelf of ocean bottom in the bering and chukchi seas 但今年夏天北极冰帽面积缩小至历史最低记录，使海冰推移至白令海和楚科奇海一带底栖生物丰富的浅大陆架外围的远北地区。
Mars ' s polar ice caps expand each winter as carbon dioxide in the planet ' s atmosphere freezes , the researchers say . but during spring , warmer weather slowly melts the expanded ice 由于火星大气中的二氧化碳的凝结，火星的极地冰帽每个冬天都在扩大。春天，温暖的天气缓慢得融化这些扩展的冰。
But the lowest summer ice cap on record put sea ice far north of the outer continental shelf , the shallow , life - rich shelf of ocean bottom in the bering and chukchi seas 但今年夏天北极冰帽面积缩小至历史最低记录，使海冰向北推移，远离了白令海和楚科奇海一带海底生物丰富的浅大陆架外围地区。
The arctic ice cap will melt completely within the next century if carbon dioxide emissions continue to heat the earth ' s atmosphere at current rates , according to an international study 根据一项国际研究，如果二氧化碳继续不断排放，使得地球空气不断生温。到下个世纪，北极的冰盖将会完全的融化。
Although it would take hundreds of years for the full effects to be felt , the polar ice caps eventually would melt completely , causing sea levels to rise by 70m to 100m ( 230ft to 330ft ) 虽然要几百年时间才能感受到升温对各方面的影响，极地冰帽最终将完全融化，使海平面升高70到80米（ 230到330英尺） 。
The expedition was scheduled to take around 60 days - but 47 - year - old rosie was picked up after enduring a long , chilly 84 days on the shifting ice cap 现年47岁的斯坦斯原定大约用60天时间来完成冒险计划，但她在湿滑的冰层上走了84天还没有完成目标后，就选择了放弃。而她最终离自己的终极目标还有89英里。
But a puzzling general pattern , seen the past three decades , persisted : the most significant warming occurred in the arctic , where the ice cap is shrinking at an alarming pace 不过，在过去近30年来一直存在的一个令人迷惑的温度变化仍然在持续多数显著的变暖现象发生在北极，北极冰山正以令人担忧的速度迅速减少。
The first mistake made by mr gore , said mr justice burton in his written judgment , was in talking about the potential devastation wrought by a rise in sea levels caused by the melting of ice caps 第一个错误是高尔先生所说的，英国伦敦高等法院法官柏顿在他的书面意见，有提到熔化中的冰帽，所造成现在海平面上升所带来潜藏性破坏。
The burning of fossil fuels for travel and electricity generation is creating vast amounts of so - called green - house gases that are heating the planet , melting ice caps and putting millions of people at risk of drowning 旅行和发电用途燃烧的石化燃料产生大量温室效应气体，造成地球温度上升、冰帽融化，并使数百万人面临淹死危机。
If the temperature on the earth continues go up from year to year , the polar ice caps will begain to melt and in all likelihood , half of the buildings in coastal cities will disappear beneath splashing sea waves 如果地球上的温度继续年复一年地上升，极地的冰帽将会开始融化，沿海城市中的一半建筑物很可能会消失在劈啪飞溅的海湾下面。
