The Earth's North and South Poles are known as the cryospheres, regions blanketed with snow and ice.

地球的南北极众所周知的拥有大量冰雪。

The study drew on recent evidence from scientific studies of the Antarctic Ocean, atmosphere, cryosphere and biosphere.

这项研究利用了南极海洋、大气、冰冻圈和生物圈科学研究的最新证据。

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。
