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。
But there ' s no way to designate the same for disappearing sea ice ; and besides , all the existing protections of polar bear habitat would stillapply , and couldn ' t be extended much further anyway 但这样的办法没法照搬到消失的冰盖上；另外，所有现有的保护北极熊栖息地的措施仍会延续，而且这些措施也没什么可以增加的了。

Duluth , minn . ? lake superior has been warming even faster than the climate around it since the late 1970s due to reduced ice cover , according to a study by professors at the university of minnesota duluth 明尼苏达杜勒斯大学的一项研究发现：自从70年代末期以来，冰盖的减少使得苏必利尔湖较其周围气候环境变暖的速度更快。
And because the deadline for scientific papers to be included in the ipcc ' s report was some time ago , its deliberations have excluded some alarming recent studies on the acceleration of glacier - melting in greenland 此外，由于交稿时间所限，报告虽刊登了数篇科学论文，却未能将近来有关格陵兰岛冰盖加速融化的研究纳入其中。
Ice dam , ice cover and ice jam , which are farmed by stack , jammed and collective ice , can increase river resistance and water stage , resulting in flood , construction damage and navigation problems 冰块堆积，堵塞和聚集形成的冰坝、冰盖和冰塞会导致河道阻力增加，致使上游水位上涨，并可能造成冰期洪水，建筑物破坏，航运不畅等危害。
