As Arctic sea ice melts, the darker ocean absorbs more sunlight and speeds melting.
覆盖在北极海面上的冰雪融化后，颜色更深的海水将吸收更多的阳光，从而加速了融化进程。
Eventually, homes will belost as more ice melts each summer, and maybe all of Bykovsky, too.
夏天，更多的冰融化，最终，房屋乃至整个村庄，将会被海水吞没。
Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
当然，当冰融化的时候，会降低周围水中的盐度。
Nowadays, when the ice melts earlier in the spring, the plants seem to be eager to start growing.
现今，冰会在春天较早的时候融化，各种植物似乎都迫不及待地要开始生长。
As more ice melts, more dark open water is exposed, which absorbs more heat, accelerating the melting.
随着更多的冰融化，更大的深色无冰海面被露出。它们会吸收更多的热量，从而加剧冰的融化。
When ice melts and disappears this "albedo" effect is lessened, contributing to a rise in temperature.
冰层融化消失后，这种“反射能”效应减弱，从而导致气温上升。
The process is self-perpetuating: as ice melts, the ocean absorbs more heat and melts more ice, and so on.
这个过程能自我循环：当冰层溶解时，海洋能吸收更多的热量，从而溶化更多的冰。
The scientists say that as more sea ice melts, polar bears have to swim greater distances in search of food.
科学家表示，由于越来越多的冰层融化，北极熊必须游更远的距离来寻找食物。
When sea ice melts, the newly exposed dark water absorbs radiation rather than reflecting it, as snow or ice would.
当海冰融化时，刚刚暴露出来的水对光线的吸收作用大于反射作用，不像雪或冰那样，对光线更多的是反射作用。
Even after ice melts, some of those tetrahedrons almost always remain, like tiny ice cubes 100 molecules wide.
即使在冰融化后，也几乎总会残留一些这种四面体，如100个分子那么宽的微小冰立方体。
But when the ice melts, the sun warms ocean waters. Walter Meier is a scientist with the National Snow and ice Data Center.
但是一旦冰融化了，太阳就能使海水升温。沃特·米亚尔是一个在国家冰雪数据中心工作的科学家。
Even an old ally like Norway, worried about Russia's polar ambitions as the ice melts, thinks it is time to rebalance priorities.
即使是像挪威这样老资历的盟国——该国担心随着冰层消融俄罗斯对于北极的野心将昭然若揭——也认为是时候重新平衡优先考虑事项了。
They are now trying to prove the viruses found in lake ice can actually survive well enough to re-infect birds when the ice melts.
他们现在正在努力证明，在湖冰中找到的病毒确实能很好地活下来，在冰融化之时再次感染鸟类。

他们现在正在努力证明，在湖冰中找到的病毒确实能很好地活下来，在冰融化之时再次感染鸟类。
As the comet nears the sun, its ice melts, releasing gas and dust that stream away into space. (Explore an asteroids and comets interactive.)
当彗星靠近太阳时，它的冰层融化，释放的气体和尘埃远远地飘向太空。(探索一颗小行星和彗星们的相互作用。)
Sea ice melts in summer. Without ice for a platform they cannot hunt seals, their main prey-and so they fast, eating almost nothing until ice forms in autumn.
夏季，海上冰雪消融，没有冰面作为平台，它们就无法捕食它们最主要的食物来源-海豹，所以，它们几乎不吃什么东西，禁食直到秋季冰块再次成型。
The second result is that the Arctic, a place where any warming trend would be amplified by changes in local absorption of heat as the ice melts, does indeed show signs of rapid warming.
第二，是北极的冰化。在北极，气候变暖的迹象更明显，因为大量的冰吸热融化，显示气候在加速变暖。

But even if the ice melts as fast as shippers hope (and scientists fear), navigation is likely to demand strengthened hulls, higher insurance and extra training for crews, all adding to the costs.
但是即使冰融化得象航运者们希望的那样快(科学家们担心的)，航行可能需要加固船体、更高的保险和对全体船员附加的训练，所有的都增加了开销。
A thinner isotherm allows faster turnover of warmer waters from below, which speeds ice-melt. The process is self-perpetuating: as ice melts, the ocean absorbs more heat and melts more ice, and so on.
较薄的等温线使下面温暖的海水快速流转，从而加快冰融化。
Glaciers are slowly moving masses of ice that have accumulated on land in areas where more snowfalls during a year than melts.
冰川正在缓慢地移动大量的冰，这些冰是在每年降雪量大于融化量的地区，在陆地上累积起来的。
