Seventh Assessment Report of the IPCC has nine Lead Authors from the Potsdam Institute

21.08.2025 – The Intergovernmental Panel on Climate Change (IPCC) has now appointed 664 experts from 111 countries to produce the “Seventh Assessment Report” on the state of climate science, which is highly relevant for policy advice. Amongst them are nine Lead Authors from the Potsdam Institute for Climate Impact Research (PIK). The new Assessment Report will be published in 2028 and 2029. It will comprise several thousand pages and be divided into three volumes prepared by scientific Working Groups, plus a synthesis report.

For Working Group 1 (“The Physical Science Basis”), the IPCC has appointed, among others, the PIK researchers Nico Bauer, Niklas Boers and Ricarda Winkelmann as Lead Authors. In Working Group 2 (“Impacts, Adaptation, and Vulnerability”), Franziska Piontek, Iulii Didovets and Barbora Šedová will serve as Lead Authors. And in Working Group 3 (“Mitigation of Climate Change”), William Lamb, Jan Minx and Elmar Kriegler from PIK were appointed as Lead Authors.

The authors of the new report were selected from a pool of 8,771 persons nominated by governments as IPCC observer organisations. “They ensure outstanding expertise across a range of disciplines”, said IPCC Chair Jim Skea upon announcement of the decision. “The appointment means that work on the report can now begin.” The first Lead Author meeting is scheduled for early December.
