PIK scientists are actively involved in the activities of the Intergovernmental Panel on Climate Change (IPCC). From October 2008 until October 2015, Ottmar Edenhofer had been one of three Co-Chairs of the IPCC Working Group III “Mitigation of Climate Change“. During his tenure, the WGIII Technical Support Unit (TSU), which coordinated and administered the Working Group’s activities, was hosted by PIK.
During the course of the IPCC’s fifth assessment cycle, the WGIII published the Special Report on Renewable Energy Sources and Climate Change Mitigation. In April 2014, the o the Fifth Assessment Report (AR5) of the IPCC was finalized and, after the approval of the Summary for Policymakers by the IPCC plenary, released. Ottmar Edenhofer and members of the WGIII TSU are also authors of the IPCC’s Synthesis Report. With the publication of the Synthesis Report in November 2014, the Fifth Assessment Report has been completed.
Several PIK scientists are authors of the AR5. They contributed to chapters of all three IPCC Working Groups’ parts of the Fifth Assessment Report, dealing with issues ranging from sea-level change to assessing transformation pathways.
