cryosphere
含义: The portions of the Earth's surface where water is present in solid form, including ice sheets, glaciers, sea ice, snow cover, and permafrost.
The cryosphere plays a critical role in regulating global climate: ice sheets reflect solar radiation (the albedo effect), permafrost stores vast quantities of methane and carbon dioxide, and glaciers serve as freshwater reserves for billions of people. As global temperatures rise, the cryosphere is shrinking at an accelerating rate, contributing to sea-level rise and feedback loops that amplify warming. The IPCC dedicated a special report to the ocean and cryosphere in 2019. It collocates with 'melting,' 'permafrost,' 'sea ice,' 'albedo,' and 'feedback.'
