Scoping Meeting for the IPCC AR5 Synthesis Report
25-27 August 2010, Liege, Belgium

The AR5 Synthesis Report (SYR) will synthesize and integrate material contained in the three Working Group Reports and Special Reports produced during the 5th or previous Assessment Cycles. It would be written in a "non-technical style suitable for policymakers and address a broad range of policy-relevant, but policy-neutral questions".
At its 30th session held in Antalya, Turkey, in April 2009 the IPCC decided that the scoping of the AR5 Synthesis Report (SYR) would begin with the first scoping meeting, while provisions were also made for a special meeting dedicated to scoping the SYR.

The AR5 Scoping Meeting, held in Venice, Italy, in July 2009 recommended that the Synthesis Report be organized around four major topic areas: Observed Changes and their Causes; Future Changes (in the short and long term); Response, and Transitions and Transformation.
The Scoping Meeting for the AR5 SYR was held in Liege, Belgium, from 25 to 27th August 2010 to further develop scope, structure and content of the SYR.  The scoping document resulting from that meeting was submitted for consideration by the Panel at its 32nd Session, held in Busan, Republic of Korea (11-14 October 2010), which agreed on Scope, Content and Process for the Preparation of the Synthesis Report (SYR) of the IPCC Fifth Assessment Report (AR5).
