But when climates warm or there’s less snow, glaciers retreat and grow smaller.

但是当气候变暖或降雪量减少时， 冰川会退缩并变小。

The cryosphere is the frozen part of the earth system and includes snow, glacier and sea ice.

冰冻圈是地球系统的冻结部分，包括雪、冰川和海冰。

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。
