The cryosphere refers to the parts of the Earth's surface where water is in solid form. This includes ice sheets, glaciers, ice caps, snow, sea ice, and frozen ground (permafrost). The term originates from the Greek word "kryos," meaning frost or cold. The cryosphere plays a crucial role in regulating Earth's climate. Its bright, white surfaces reflect solar radiation back into space, a phenomenon known as the albedo effect, which helps to keep the planet cool.

Changes in the cryosphere are a significant indicator of global warming. Rising global temperatures lead to the melting of ice sheets and glaciers, contributing to sea-level rise. The loss of sea ice in the Arctic also impacts weather patterns and marine ecosystems. Permafrost thaw releases trapped greenhouse gases like methane and carbon dioxide, further accelerating climate change. Scientific monitoring of the cryosphere provides vital data for understanding and predicting future climate scenarios. The distribution and dynamics of snow cover, for instance, affect water resources for millions of people downstream from snow-fed rivers. The study of the cryosphere, or cryology, is a multidisciplinary field that draws on glaciology, permafrost science, snow science, and oceanography.
