The IPCC was established jointly by the United Nations Environment Program and the World Meteorological Organization in 1988. The purpose of the IPCC is to evaluate information in the scientific and technical literature related to all significant components of the climate change issue. The IPCC draws on hundreds of the world's expert scientists as authors and thousands as peer reviewers. Leading experts on climate change and environmental, social and economic sciences from around 60 countries have helped the IPCC prepare regular assessments of the scientific evidence for understanding global climate change and its consequences. Thanks to its ability to report on climate change, its consequences and the feasibility of adaptation and mitigation measures, the IPCC is considered the official advisory body for the entire world. government on the state of science on climate change. For example, the IPCC organized the development of internationally accepted methods for conducting national inventories of greenhouse gas emissions.
