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。
Anyone who has ever walked on a frozen lake, gone ice skating or tried curling knows that ice is slippery and that it takes practice to move with any kind of confidence.

The new study showed ice sheets like the Greenland ice sheet can respond to such warming on the order of decades rather than the centuries projected by conventional thermal models.
这项新的研究显示，像格陵兰冰盖这样的冰层对这种变暖趋势的反应在几十年内就会显现，而非传统的热模型所预测的那样百年后才会出现。
Many professional runners use ice baths to reduce soreness after runs. If you can't tolerate an ice bath, use ice packs on sore areas.
许多专业跑步者会洗冰浴以减轻跑步后的酸痛。如果你不能忍受冰浴，在酸痛处敷上冰袋。
Snow and ice normally reflects much of the sun's energy — up to 90 percent — back the way it came. But a layer of soot on top of the ice will absorb the sunlight, warm the ice beneath, and melt it.
雪和冰反射了大概超过90%左的太阳能量，然而，附着在冰层上方的烟尘，会加热下方冰层，将他们融化成水。
Ice still fringes much of the land, but it is thinning. In many places, particularly around Banks Island, the land-bound sea ice is blue, pointing to thin ice or the presence of water on the ice.
在很多地方，尤其是班克斯岛周边，陆地边沿的海上浮冰是蓝色的，表明冰层较薄或浮冰上有水。
