IPCC Review by the IAC

The IPCC Review by the IAC

The InterAcademy Council IAC's review of the Review of the Processes and Procedures of the IPCC is now available. A number of recommendations for improvement were made. The IAC report also made positive statements:

  • Through its assessment reports, the IPCC has gained enormous respect and even shared the Nobel Peace Prize in 2007 for informing climate policy and raising public awareness worldwide.

  • The Committee found that the IPCC assessment process has been successful overall.



The Committee concludes that the IPCC assessment process has been successful overall and has served society well. The commitment of many thousands of the world’s leading scientists and other experts to the assessment process and to the communication of the nature of our understanding of the changing climate, its impacts, and possible adaptation and mitigation strategies is a considerable achievement in its own right. Similarly, the sustained commitment of governments to the process and their buy-in to the results is a mark of a successful assessment. Through its unique partnership between scientists and governments, the IPCC has heightened public awareness of climate change, raised the level of scientific debate, and influenced the science agendas of many nations. However, despite these successes, some fundamental changes to the process and the management structure are essential, as discussed in this report and summarized below.


HERE is the IAC summary. Recommendations were made for the IPCC in these fields:

  • Governance and Management

  • Review Process

  • Characterizing and Communicating Uncertainty

  • Communications

  • Transparency

HERE is RealClimate's assessment:

The Inter-Academy Council report on the processes and governance of the IPCC is now available. It appears mostly sensible and has a lot of useful things to say about improving IPCC processes – from suggesting a new Executive to be able to speak for IPCC in-between reports, a new communications strategy, better consistency among working groups and ideas for how to reduce the burden on lead authors in responding to rapidly increasing review comments.

The IAC report makes sensible recommendations for improvement of the IPCC process. The IAC report does not deal with the substance of the IPCC reports.

The right-wing contrarian media is already distorting the IAC report, ignoring the positive comments.

It should be emphasized that the IPCC has been under fierce attack for years by right-wing contrarian media, supported by fossil fuel supporters and libertarians to further their economic interests and political agendas. See HERE.

The InterAcademy Council

The eighteen-member InterAcademy Council Board is composed of presidents of fifteen academies of science and equivalent organizations—representing Argentina, Australia, Brazil, China, France, Germany, India, Indonesia, Japan, South Africa, Turkey, the United Kingdom, and the United States, plus the African Academy of Sciences and the Academy of Sciences for the Developing World (TWAS)—and representatives of the IAP: the global network of scientific academies, the International Council of Academies of Engineering and Technological Sciences (CAETS), and the InterAcademy Medical Panel (IAMP) of medical academies.
