About the IPCC
This led to the establishment of the Intergovernmental Panel on Climate Change (IPCC), in 1988, parented by two UN organisations: the World Meteorological Organisation(WMO) and the UN Environment Programme (UNEP).
Its purpose then, as it is now, is to prepare a report on all aspects of climate change and its impacts, with a view to formulating realistic response strategies. The report is based on a review of all available, peer-reviewed, published scientific/technical literature. The information is assessed on a comprehensive, objective, open and transparent basis. Its reports are policy relevant but not policy prescriptive.
In more than two decades since its establishment, the IPCC has produced 5 reports.
The First Assessment Report (FAR) was produced in 1990. As a consequence of this report, the United Nations General Assembly decided to initiative negotiations for an effective framework convention on climate change (ultimately to be known as the United Nations Framework Convention on Climate Change (UNFCCC), or more generally as the UN climate negotiations.
The Second Assessment Report: Climate Change (SAR) was produced in 1995.
The Third Assessment Report: Climate Change (TAR) was produced in 2001.
The Fourth Assessment Report: Climate Change (AR4) was produced in 2007.The same year, the IPCC was awarded the Nobel Peace Prize jointly with former US vice president Al Gore in recognitionof their work on climate change.
The Fifth Assessment Report (AR5) was produced in 2013/2014. It comprises three main reports, and a final Synthesis Report
- The first report of AR5- from Working Group I - was released in September 2013 (The Physical Science Basis) and assesses the physical scientific aspects of climate change.
- The second report of AR5- from Working Group II - was released in March 2014 (Impacts, adaptation and vulnerability).
- The third report of AR5 (Mitigation on climate change) was released in April 2014.
- The final Synthesis Report of AR5 was released in October 2014.
This is the third in a series of four reports being prepared by the world’s leading climate authorities in the Intergovernmental Panel on Climate Change (IPCC). It provides a comprehensive assessment of the options for mitigating climate change. It draws on the scientific literature accepted for publication up to 4 October 2013. In all, 38,315 comments were received for this report; there were 879 Expert Reviewers from 66 countries, and 38 Governments made comments to the report.
