No. There's also plastics, cellulose, foam, shaved ice, snow blanket, snow membranes, they all have their pluses and minuses.

不。另外还有塑料的、纤维素的，泡沫的，小冰渣，雪毯，雪膜，这些东西都各有优缺点。

Also, when sea ice, snow, glaciers and permafrost melt, darker land or ocean surfaces can absorb more energy from the sun, causing additional heating.

另外，当海冰、积雪、冰川和永久冻土融化时，深色的陆地或海洋表面会从太阳吸收更多的能量，增加额外的热量。

That may sound small and benign, but it masks much more critical change in a place where the line between ice and no ice, snow and rain, can be razor thin.

这数字听起来可能不大，比较微妙，但它掩盖了这个地区一个更为关键的变化，那就是有冰还是无冰，下雪还是下雨的界线变得很难区分。
