Intergovernmental Panel on Climate Change Fourth Report

The Intergovernmental Panel on Climate Change (IPCC) (LINK TO http://www.ipcc.ch/about/index.htm) assesses the latest scientific, technical, and socio-economic literature produced worldwide relevant to the understanding of the risk of human-induced climate change, its observed and projected impacts, and options for adaptation and mitigation. The IPCC was established in 1988 to provide decision-makers and others interested in climate change with an objective source of information about climate change. It does not conduct any research nor does it monitor climate related data or parameters.

The IPCC’s Fourth Assessment Report, composed of four volumes (one for each of the IPCC Working Groups and a synthesis report), was published in 2007. The “Summary for Policymakers” of each report is linked below.
