The Intergovernmental Panel on Climate Change (IPCC) was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988.

IPCC was established to provide policymakers with regular scientific assessments on the current state of knowledge about climate change.

IPCC initial task was to prepare a comprehensive review and recommendations with respect to the state of knowledge of the science of climate change; the social and economic impact of climate change, and potential response strategies and elements for inclusion in a possible future international convention on climate.

IPCC is an organization of governments that are members of the United Nations or WMO. The IPCC currently has 195 members.

IPCC Panel elects a Bureau to provide guidance on the scientific and technical aspects of its work, to give advice on related management and strategic issues, and take decisions on specific issues within its mandate as stated in the Principles Governing the Work of the IPCC.

How does the IPCC work?

The Intergovernmental Panel on Climate Change is a huge and yet very small organization. Thousands of scientists from all over the world contribute to the work of the IPCC on a voluntary basis as authors, contributors and reviewers. None of them is paid by the IPCC. The work of the IPCC is guided by a set of principles and procedures.

The Panel takes major decisions at Plenary Sessions of government representatives. A central IPCC Secretariat supports the work of the IPCC.

The IPCC is currently organized in 3 Working Groups and a Task Force. They are assisted by Technical Support Units (TSUs), which are hosted and financially supported by the government of the developed country Co-Chair of that Working Group/Task Force. A TSU may also be established to support the IPCC Chair in preparing the Synthesis Report for an assessment report.

Working Group I deals with "The Physical Science Basis of Climate Change", Working Group II with "Climate Change Impacts, Adaptation and Vulnerability" and Working Group III with "Mitigation of Climate Change". Working Groups meet in Plenary session at the level of government representatives. The main objective of the Task Force on National Greenhouse Gas Inventories is to develop and refine a methodology for the calculation and reporting of national greenhouse gas emissions and removals.

Besides the Working Groups and Task Force, further Task Groups and Steering Groups may be established for a limited or longer duration to consider a specific topic or question. One example is the Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA).
