Researchers from the Energy (ENE) program participated in the authors meeting as Coordinating Lead Author (Dr. Joeri Rogelj), Lead Author (Dr. Keywan Riahi) and Contributing Author and Chapter Scientist (Dr. Daniel Huppmann). The 4th Lead Authors meeting is dedicated to the chapter breakouts to review the Second Order Draft SOD reviewer comments and develop the chapters for preparing the Final Draft (FGD) due by 20 May 2018. The Technical Support Unit (TSU), will share the FGD for an eight week Final Government Review on 4 June 2018.

About IPCC

The Intergovernmental Panel on Climate Change (IPCC) was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socioeconomic impacts.

Indeed IIASA’s pioneering research into climate change in the 1970s and 1980s played a key role in establishing the IPCC. Read more about IIASA's contribution to the field in the Options Magazine article, 40 Years' Research into Climate Change. Since then, numerous IIASA scientists have been authors and reviewers of the IPCC’s reports. IIASA’s approach of merging interdisciplinary and international research ensures its scientists are well experienced to provide expertise in understanding problems such as climate change that also crosses national and disciplinary boundaries.
