The AR5, summarizing the state of scientific knowledge about climate change, is going through an elaborate system of drafting, review by experts and governments, and revision to ensure that it meets the highest standards, is comprehensive and reflects the published literature and a range of scientific viewpoints. The main stages of the IPCC review process are the review of the “first-order draft” (FOD) by scientific experts, the review of the “second-order draft” (SOD) by experts and governments and the government review of the final draft of the summary for policymakers. Following this, the final draft report and its summary for policymakers are submitted for acceptance and approval to the IPCC Plenary.
