Intergovernmental Panel on Climate Change (IPCC)
The Intergovernmental Panel on Climate Change is the United Nations body for assessing the science related to climate change. It provides regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. Created in 1988 by the World Meteorological Organization and United Nations Environment Program, IPCC provides governments and U.N.-led summits with scientific information they can use to form climate policies.
