Vladimir Ryabinin World Climate Research Programme WMO/ICSU/IOC 1 st IGOS-P Cryosphere Theme workshop, 2-4 March 2005, Kananaskis, Canada

World Climate Research Programme (WCRP)

Established 1980 Sponsors: WMO (1980+), ICSU (1980+) and IOC (1993+) Objectives

To determine the predictability of climate

To determine the effect of human activities on climate

Earth System Science Partnership for Global Change Research

• an integrated study of the Earth System, • the changes occurring to the System, and • the implications for global sustainability.

Start Integrated Regional Studies

Earth System Questions

e.g. What are the critical thresholds/ switches/ hot spots

Implications of changes in freshwater flux from the Greenland ice sheet for the climate of the 21 st century

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

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?

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

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

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 Marine Cryosphere • GOOS and JCOMM sea-ice compartments Combined system for observations of soil, meeting requirements of hydrology, geocryology, climate and biogeochemical modelling • WGMS, GLIMS Alpine Cryosphere

To combine?

IGOS-P 11, 27 May 2004, Rome

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

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.
