AR5 provides a clear and up to date view of the current state of scientific knowledge relevant to climate change. It consists of three Working Group (WG) reports and a Synthesis Report (SYR). Further information about the outline and content and how the AR5 has been prepared can be found in the AR5 reference document and SYR Scoping document. Information about how the AR5 was prepared can be found here.
The Synthesis Report distils and integrates the findings of the three working group contributions to the IPCC Fifth Assessment Report — the most comprehensive assessment of climate change yet undertaken, produced by hundreds of scientists — as well as the two Special Reports produced during this cycle.
