Climate change was identified as an urgent global problem that requires governments to unite their efforts to prepare for potential climate risks at the First World Climate Conference in 1979. This recognition led to the establishment of the Intergovernmental Panel on Climate Change (IPCC) in 1988 to assess the magnitude and timing of changes and estimate their impacts. The IPCC published its First Assessment Report in 1990, which became a basis for negotiations on a climate change convention under the United Nations General Assembly. Between February 1991 and May 1992, the Intergovernmental Negotiating Committee for a Framework Convention on Climate Change met five times under the auspices of the General Assembly, and the Convention text was adopted on May 9, 1992 at the United Nations Conference on Environment and Development, held in Rio de Janeiro, Brazil, where 154 states signed. The Convention entered into force on March 21, 1994. It has near universal membership with 194 Parties (member countries) having ratified (UNFCCC, 2006).
