IIASA’s researchers have played important roles in the Intergovernmental Panel on Climate Change’s (IPCC) reports into climate change since the Panel was established in 1988. The IPCC’s reports are widely recognized as the most important source of scientific, technical and socio-economic information about climate change, its impacts, and possible response options. Through the IPCC’s relationship with the United Nations Framework Convention on Climate Change (UNFCCC), the IPCC’s assessments and reports provide independent scientific advice on the complex issue of climate change directly to the 194 countries that have currently ratified the UNFCCC. In recognition of the IPCC's efforts to disseminate greater knowledge about man-made climate change, the IPCC was awarded the 2007 Nobel Peace Prize.

Numerous IIASA scientists have been lead authors and reviewers of the IPCC’s second, third, and fourth assessment reports along with some of the special reports such as the IPCC’s Special Report on Emissions Scenarios—a contribution far greater than some of the world’s most prestigious universities. But not surprising. 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.

Indeed IIASA’s pioneering research into climate change in the 1970s and 1980s played a key role in establishing the IPCC (more information). Work at the IPCC has just begun on its Fifth Assessment Report which is due for completion between 2013 and 2014. Nine IIASA scientists have been selected as Lead Authors and Lead Reviewers.
