The objectives of the World Climate Research Programme (WCRP) are to develop the fundamental scientific understanding of the physical climate system and climate processes needed to determine to what extent climate can be predicted and the extent of human influence on climate. WCRP encompasses studies of the global atmosphere, oceans, sea and land ice, and the land surface which together constitute the Earth's physical climate system. It is co-sponsored by the World Meteorological Organization, the International Council for Science, and the IOC of UNESCO.
