Figure 1.10 The Climate Agenda embraces the activities of the World Climate Programme (WCP) and its subsidiary programmes, the Global Climate Observing System (GCOS) and climate-related elements of the Global Ocean Observing System (GOOS) and Global Terrestrial Observing System (GTOS), as well as elements of the International Council for Science’s (ICSU) International Geosphere-Biosphere Programme (IGBP). The intergovernmental and non-governmental agencies that sponsor the WCP are represented on the currently inactive Inter Agency Committee for the Climate Agenda (IACCA) together with representatives of the Intergovernmental Panel on Climate Change (IPCC) and the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). The GCOS underpins and supports the individual components of the World Climate Programme (WCP) but is not formally a part of it. An associated programme which is relevant to the Climate Agenda but not formally part of it is the International Human Dimensions of Environmental Change Programme (IHDP) of ICSU and the International Social Science Council (ISSC).
