10. Implications of changes in freshwater flux from the Greenland ice sheet for the climate of the 21 st century (Fichefet et al., GRL, 2003) Climate-change scenario with an AOGCM coupled to a 3-D model of the Greenland ice sheet Changes in annual mean total fresh-water flux from Greenland Freshwater flux from Greenland prescribed Freshwater flux from Greenland interactive Changes in annual mean SAT (in °C) averaged over years 2096-2100 Collapse of the THC + realistic modelling of ice sheets, Ayako Abe-Ouchi, see CliC Conference

11. Current tasks for WCRP as a whole (only ones dealing with the cryosphere, first slide): Seasonal prediction (what is predictability potential in cryospheric part of the climate system?) Encouraging results in some areas: links do exist Projection of the mean sea level rise (we address the area of highest uncertainty) Ice Age simulations – for the first time there is a potential Cryospheric input to water management – more and more important for national economies

12. Current tasks for WCRP as a whole (only ones dealing with the cryosphere, continuation but possibly not the end): Future of sea-ice in the Arctic Ocean Possibility of abrupt climate change Carbon – its links to cryospheric influences Monsoon prediction (involving Tibetian Plateau) “Cryospheric” contribution to Earth System models and DAS A need to think about a reanalysis of the cryosphere? On-going polar reanalysis Is CEOP’s approach applicable?

14. Considerations (1): Group on Earth Observations GCOS (Implementation Plan: UNFCCC, Kyoto) WCRP WGOA, projects, GEWEX, CLIVAR, SOLAS, OASIS, AICI, NEESPI, IPA, ISAC Work with relevant panels of the WCRP: IPAB, IABP, Arctic Climate Panel, Southern Ocean Panel, Data Management & Information Panel CliC Panel on Cryospheric Observations, role in IGOS-P and in advice to GCOS

15. Considerations (2): Polar GOOS Mix of proven and experimental technology IPY – opportunity National activities (e.g, such as CRYSYS) Regional bodies, ICARPII

16. IGOS-P Theme on Cryosphere by CliC and SCAR, to be led by CliC Obs. Panel GCOS/GTOS: GTN-P, GTN-G, GTN-H, CALM, etc. ARCTIC-HYCOS, GTN-R, GTN-L, etc. AOOS SO OS GOOS and JCOMM sea-ice compartments WGMS, GLIMS Combined system for observations of soil, meeting requirements of hydrology, geocryology, climate and biogeochemical modelling Marine Cryosphere Alpine Cryosphere IGOS-P 11, 27 May 2004, Rome To combine?

17. For Marine Cryosphere: Is it only about the sea-ice as such but may be also about observations depending on it, like ice-tethered platforms, polar oceanographic observations and also related observations? There is a need to at least indicate related systems, a chapter on dependent observations

19. Partners in the Theme Proposers: WCRP through CliC, ICSU through SCAR Chair: Jeffrey Key (NOAA) Vice-Chair: Mark Drinkwater (ESA) Core contributors from partners: CliC: Barry Goodison, Vladimir Ryabinin, Chad Dick SCAR: Colin Summerhayes WMO: Don Hinsman 23 other experts indicated agreement to contribute Not all themes yet covered by the authors

22. Approach update user requirements, study of how they are met by current, planned and prospective in situ and remotely sensed observations, propose the way forward trying to build on adequate mix of satellite and in-situ observations, try to achieve consensus on priorities and wide acceptance of the recommendations.
