About CliC

CliC is overseen by a Scientific Steering Group (SSG) responsible for overall direction and planning. The International CliC Project Office (ICPO -- hosted by the Norwegian Polar Institute serves as the administrative home for the project. The CliC science strategy is aimed at promoting and facilitating new collaborative research related to the cryosphere and climate, making links between cryospheric research and research in other disciplines, and communicating research results to policy and decision-makers and other non-scientific users. Cryospheric research coordinated by CliC covers the Arctic, Antarctic, high-elevation mountain areas, and broad regions that experience snow and permafrost. It further informs a range of stakeholders in the relevant socioeconomic domains and contributes to international efforts like the Global Framework for Climate Services (GFCS).

CliC research spans the entire diversity of the Earth’s cryosphere: marine cryosphere, terrestrial cryosphere, alpine cryosphere, and ice sheets. A balance between disciplinary specialization and multi-disciplinary collaboration allows integrating the outcomes of this research as input to assessments and predictions of the cryosphere and climate. The connection between cryospheric observations, process studies and modelling (regional and global) is an increasingly important focus for CliC.

A further influence on CliC science planning is the concept of Grand Challenges, initiated as a result of the WCRP first Open Science Conference (Denver, USA, 2011). The WCRP Grand Challenges are areas of high-priority research, where it is thought that focussing efforts of the science community, over a 5- to 10- year time frame, can result in significant progress on a science problem of societal importance. The role of permafrost thaw in the global carbon balance, the fate of the Arctic summer sea ice, and the contribution of cryosphere to global and regional sea-level rise are examples of such problems and they constitute the substance of the WCRP Grand Challenge, “Melting Ice - Global Consequences” for which CliC serves as a focal point. As such, CliC has the responsibility for planning and implementation of this Grand Challenge, which includes activities of the WCRP Polar Climate Predictability Initiative. CliC also contributes to one of the work packages of the Grand Challenge on Regional Sea Level Rise, specifically that related to the contribution of land ice to sea level.

Overarching Research Needs

They are:
1. Improved understanding and quantification of the role of the cryosphere in the global climate system, its variability and change.
2. Improved utilization of cryospheric observations as indicators of global and regional climate change.
3. Improved understanding of the physical, chemical and other processes that govern behaviour of the cryosphere, and the representation of these processes in Earth System Models.
4. Improved ability to make quantitative predictions and projections of the cryosphere in a changing climate.
