Abstract from DBPedia
    The cryosphere (from the Greek κρύος kryos, "cold", "frost" or "ice" and σφαῖρα sphaira, "globe, ball") is an all-encompassing term for those portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost). Thus, there is a wide overlap with the hydrosphere. The cryosphere is an integral part of the global climate system with important linkages and feedbacks generated through its influence on surface energy and moisture fluxes, clouds, precipitation, hydrology, atmospheric and oceanic circulation. Through these feedback processes, the cryosphere plays a significant role in the global climate and in climate model response to global changes. Approximately 10% of the Earth's surface is covered by ice, but this is rapidly decreasing. The term deglaciation describes the retreat of cryospheric features. Cryology is the study of cryospheres.

    雪氷圏（せっぴょうけん、ギリシア語で「寒冷」、「凍結」、「氷」を意味するκρύος（kryos）と「球」を意味するσφαῖρα（sphaira）から英語のcryosphereができた）は、海氷、湖氷、河川氷、積雪、氷河、氷冠、氷床、そして(永久凍土を含む)凍土を含めた、水が固体になっている地球表面の部分のことをいう。したがって、水圏と内容が幅広く重複する。雪氷圏は、地球表面のエネルギーや水分の流動、雲、降水、水文学、大気循環、大洋循環への影響を通じて生じる重要なつながりとフィードバックをもった地球の気候システムになくてはならない部分である。こうしたフィードバックの過程を通して、雪氷圏は地球の気候やそれに応じた気候モデルにおいて重要な役割を果たす。
