Intergovernmental Panel on Climate Change (IPCC)ipcc.ch – is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UN Environment) and the World Meteorological Organization (WMO) in 1988 to provide policymakers with regular scientific assessments concerning climate change, its implications and potential future risks, as well as to put forward adaptation and mitigation strategies. It has 195 member states.

External Reviews
A Critical Assessment of the Intergovernmental Panel on Climate Change – The Intergovernmental Panel on Climate Change (IPCC) has become a hugely influential institution. It is the authoritative voice on the science on climate change, and an exemplar of an intergovernmental science–policy interface. This book introduces the IPCC as an institution, covering its origins, history, processes, participants, products and influence. Discussing its internal workings and operating principles, it shows how IPCC assessments are produced and how consensus is reached between scientific and policy experts from different institutions, countries and social groups. A variety of practices and discourses – epistemic, diplomatic, procedural, communicative – that make the institution function are critically assessed, allowing the reader to learn from its successes and failures. This volume is the go-to reference for researchers studying or active within the IPCC, as well as invaluable for students concerned with global environmental problems and climate governance. This title is also available as Open Access via Cambridge Core.


The IPCC assesses the thousands of scientific papers published each year to tell policymakers what we know and don’t know about the risks related to climate change. The IPCC identifies where there is agreement in the scientific community, where there are differences of opinion, and where further research is needed. It does not conduct its own research.

The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals. All of these are supported by Technical Support Units guiding the production of IPCC assessment reports and other products.
