IPCC Full Assessment Reports compile the knowledge on climate processes, impact, adaptation and mitigation.
The reports are compiled over a range of five to seven years. More than thousand scientists around the world are involved as authors or reviewers. The reports consist of several volumes of about 1000 pages each.
The reports normally contain 3 volumes (one volume per working group: WG I, WG II, WG III), as well as a cross-group synthesis report. In addition, there is a general summary and a summary especially for policy makers.
