Professor Ulrich Cubasch, professor and chair of Interactions in Earth’s Climate System at the Institute of Meteorology, Freie Universität, and Professor Martin Jänicke, founding director of the Environmental Policy Research Centre, Freie Universität, have been selected as two of the lead authors and review editors for the upcoming fifth assessment report of the Intergovernmental Panel on Climate Change (IPCC). Of the 830 authors selected from around the world, 36 of the climate researchers are from German universities and research institutions. This number represents only a third of those nominated by the German federal government. Since 1990 Ulrich Cubasch has contributed to all the IPCC reports, which were awarded the Nobel Peace Prize in 2007.
