汉译英试题训练

请将下面这段话翻译成英文：
全球气候变暖是近年来全球一直热议的话题,是一种“自然现象”。全球变暧会使全球降水量重新分配，冰川(glacier)和冻土(permafrost)消融，海平面上升等，既危害自然生态系统的平衡，更威胁人类的食物供应和居住环境。有一个有趣的现象，就是全球变暧对有些地区是坏事，而对其他地区却是好事，比如，南北极的寒冷地区由于温度升高，导致冰川融化，动物栖息地减少。而在中国东北地区，天气变暖意味着可以种植冬季农作物，从而增加农业收入。

翻译及详解

参考翻译
Global warming, a natural phenomenon,has been a heated topic in recent years. Global warming will redistribute global rainfall, make glacier and permafrost melt and sea level rise, which not only does harm to the balance of natural ecosystem, but also threats human's food supply and living environment. It's interesting that global warming is bad for some places but good for other regions. For example, because temperature in cold areas in Antarctic and Arctic goes up, glacier will melt, thus making the habitat of animals decrease. While in the northeast of China, becoming warm means being able to plant grains of winter, thus raising agricultural revenue.
