The Fifth Assessment Report (AR5) will provide an update of knowledge on the scientific, technical and socio-economic aspects of climate change.
It will be composed of three working group reports and a Synthesis Report (SYR). The outline and content can be found in the
AR5 reference document and
SYR Scoping document.
The Working Group (WG) Reports and Synthesis Report will be completed in 2013/2014:
WG I: The Physical Science Basis 23-26 September 2013
WG II: Impacts, Adaptation and Vulnerability 25-29 March 2014
WG III: Mitigation of Climate Change 7-11 and 13 April 2014
More than 800 authors are involved in writing the reports. Several sets of
Lead Author meetings have been held and the expert review of the Working Group contributions has been completed.
The IPCC has now begun the government and expert review of the Working Group contributions. For further information on the review
process and how to participate please follow this link. For an update on
