Climate and Cryosphere (CliC) is a core project of the World Climate Research Program and a global community of scientists dedicated to investigating the cryosphere and its interactions with the climate system. The organization's mission is to advance the understanding of climate-driven changes in the frozen parts of the planet and to support efforts to mitigate and adapt to their impacts on ecosystems and human society. CliC's work includes modeling, observations, cross-disciplinary collaboration, and stakeholder engagement.

The organization identifies key research priorities related to climate and the cryosphere and coordinates international activities to address them, while also facilitating scientific exchanges, cooperating with stakeholders, promoting early career researcher development, and communicating cryosphere-related science to policymakers, funding agencies, and the general public. CliC brings together scientists and stakeholders from around the world to plan and implement activities. The organization's sponsors play a critical role in supporting these efforts. The cryosphere, which includes snow, ice, and permafrost, plays a vital role in maintaining the Earth's climate and provides essential services to humans and animals. CliC is dedicated to improving the understanding of Earth's frozen parts and their connection to the global climate system.
