Climate and Cryosphere (CLIC)

Updated 2000-04-13

The following information about CLIC was taken from "Initiative", from the Climate and Cryosphere (CLIC) -- A New WCRP Initiative web site ( The web site features an Acrobat PDF file version of the CLIC Draft Science and Coordination Plan (dated 8 April 2000)that should be referred to for latest information. CLIC - a new initiative for WCRP Howard Cattle -- Chairman, ACSYS Scientific Steering Group At their annual meeting, held in Cape Town, South Africa from 16-20 March 1998, the Joint Scientific Committee (JSC) for the World Climate Research Programme (WCRP) reviewed the issue of the organisation of research into the Climate and Cryosphere in the WCRP. Key to this review was a paper from the ACSYS Scientific Steering Group (SSG) identifying gaps in our knowledge of some cryospheric processes in the climate system and summarising the various options for the organisation of cryospheric studies within WCRP. This paper was developed by a subgroup at the sixth ACSYS SSG meeting (November 1997), chaired by Professor Roger Barry. As a result of their review, the JSC XIX endorsed the idea of a broader programme on Climate and Cryosphere (CLIC) in the WCRP (WMO/TD-No. 929, 1998). As a first step, a Task Group was established to develop a science and coordination plan for CLIC for presentation at the twenty-first session of the JSC in March 2000, when the decision will be made on whether to initiate CLIC as a full WCRP project. More detail on the background to this can be found in an article by Hartmut Grassl and Victor Savtchenko "Cryosphere and Climate: organisation of the WCRP contribution" in WCRP Newsletter No. 2 and an article by Howard Cattle and Roger Barry "Cryosphere and Climate, The ACSYS Statement" in WCRP Newsletter No. 3. The key element of CLIC is that it will provide a globally integrated approach to the study of the role of the cryosphere in the climate system. The science and coordination plan to be developed will look at the requirements for initiating studies of cryospheric elements in which there are perceived gaps in present programmes that impact on global change research including sea level rise. It will also look at requirements for enhancing links between existing global and regional cryospheric studies and lay out a programme for ensuring accurate and appropriate treatments of cryospheric processes and interactions of the cryosphere with atmosphere, oceans and land surface in climate models and for assembling the global and regional cryospheric datasets necessary for driving and validating climate models and for diagnostic studies of the role of cryosphere in climate. Important from the coordination point of view is to provide suggestions for mechanisms for interactions with other WCRP projects, in particular GEWEX and CLIVAR, and with other cryospheric projects that could contribute to WCRP research, including identification of suitable links and mechanisms for collaboration. In summary, CLIC aims to have the following primary missions and activities: 1.Coordinates the cryospheric elements of existing projects of the WCRP (especially ACSYS, GEWEX, CLIVAR) with the aim of identifying gaps in WCRP global cryospheric research within, and at the interfaces between, these projects. 2.Coordinates, sponsors, and encourages cryosphere projects conducted under other organisations (e.g., SCAR in the southern hemisphere, IASC in the northern hemisphere) to ensure appropriate broadening of these activities and that these serve WCRP needs related to the study of cryosphere and climate. 3.Acts as the "friendly broker" between programmes and projects (both internal and external to WCRP) that are conducted in the cryosphere with some common aims, such as CLIVAR-ACSYS, ACSYS-GEWEX, ASPeCT-WCRP and MAGICS-WCRP (among others). 4.Establishes projects in the study of the role of the cryosphere in climate that cover identified gaps; these projects may involve joint sponsorship by the appropriate governmental and non-governmental bodies. The CLIC Task Group, which is responsible to the JSC through the ACSYS SSG, had its first meeting in Utrecht, The Netherlands, from 8-11 July 1998. Its co-chairs are Professor Roger Barry (NSIDC/CIRES, University of Colorado, and Dr. Ian Allison (Antarctic CRC, University of Tasmania, The meeting was hosted by the Institute for Marine and Atmospheric Research of Utrecht University. Attendees were Roger Barry, who chaired the meeting , Steve Ackley, Oleg Anisimov, Howard Cattle, Eberhard Fahrbach, Barry Goodison, Moto Ikeda, Peter Lemke, Doug Martinson, Liz Morris, Hans Oerlemans, Olav Orheim and, from WCRP, Hartmut Grassl and Victor Savtchenko. The main business was to initiate the drafting of the CLIC Science and Coordination Plan, a first version of which was discussed by the ACSYS SSG when it met in Tokyo, Japan, in November 1998. The Plan was modified to take into account the SSG’s comments. It will be presented in initial draft form to the JSC for WCRP when they meet in Kiel, Germany, in March 1999. The draft is now available as a pdf file on the ACSYS CLIC web page. Comments on the draft from the community are welcomed.
