13 August–The Intergovernmental Panel on Climate Change is preparing to launch its Fifth Assessment Report—known as AR5—starting this September. The Report, which will be released in four installments over the next year, provides an update of knowledge on the scientific, technical and socio-economic aspects of climate change.

The Fifth Assessment Report will be composed of three working group reports and a Synthesis Report. The outline and content can be found in the AR5 reference document and SYR Scoping document.

The Working Group Reports and Synthesis Report will be completed in 2013-2014, starting with Working Group I, on the Physical Science Basis, which will meet in Stockholm, Sweden 23-26 September.  This part of the Report will be launched on 27 September.

Working Group II, on Impacts, Adaptation and Vulnerability, will meet from 25-29 March 2014 in Yokohama, Japan, and Working Group III, on the Mitigation of Climate Change, is currently scheduled to meet in Berlin, Germany from 7-11 April 2014. And the AR5 Synthesis Report will be released in Copenhagen, Denmark, following a meeting from 27-31 October 2014.

More than 800 authors are involved in writing the reports. Several sets of Lead Author meetings have already been held and the expert review of the Working Group contributions has been completed. The IPCC is now in the final stages of the review process.

Several articles in the press have appeared claiming to cite the upcoming report.  But the IPCC says that reporting on any IPCC draft “is premature and can be misleading to attempt to draw conclusions. Draft reports are intermediate products and do not represent the scientific view that the IPCC provides on the state of knowledge of climate change and its potential environmental and socio-economic impacts at the conclusion of the process.”
