Climate scientist on recommended IPCC overhaul

Climate scientist on recommended IPCC overhaul
Overnight in New York, an independent report was released which recommended a major overhaul of procedures and management of the Intergovernmental Panel on Climate Change.

The report, undertaken by a 12 person team from the InterAcademy Council which represents the world's major science academies, outlines some sweeping changes, such as the installation of an executive committee for the panel to give it stronger leadership, a "rigorous conflict of interest policy" for that leadership and more rigorous review processes to deal with "grey literature" - material from non peer-reviewed sources.

The report can be downloaded here. Video of the press conferences held to launch the IAC report are available here.

The SMC sought comment from local climate scientists who have contributed to IPCC reports and/or represented New Zealand on the IPCC.

Further comments will be posted on the Science Media Centre website.

Professor Martin Manning, Director, Climate Change Research Institute, School of Government, VictoriaUniversity of Wellington comments:

"The InterAcademy Council (IAC) has run a detailed review of the process used by the Intergovernmental Panel on Climate Change (IPCC) for assessing scientific understanding and this has produced a number of useful comments that I think most climate scientists will agree with.

"Their report accepts that scientific understanding of climate change is developing rapidly and this means that the process for assessing it for policymakers needs to become more dynamic.

"The IAC recommends a stronger management structure for the IPCC process and more emphasis on a broader communication strategy. That is important, however, it will require a higher level of support from governments, and so government responses to this review are now a key factor. The review has not fully recognised that the IPCC process is controlled by what governments formally agree to in plenary sessions each year, and that there have been instances when this has specifically limited a broader communication strategy.

"The open review process for the drafts of IPCC reports means that authors have to deal with an extremely large number of comments and the IAC has followed a recommendation that I, and probably others, made about the need for some screening of these comments by independent review editors to ensure that the authors can focus on the key questions.

"The IAC puts considerable emphasis on the need to cover uncertainty in this rapidly moving field of science. Their report includes a full copy of the Uncertainty Guidance note that was written for IPCC lead authors by me and two co-authors in 2005. Recommendations for more development in this area match similar comments made by others and steps have already been made to address these in an expert meeting held by the IPCC in July.

"However, those of us who have considered this issue in detail know that there are some fundamental differences in approaches to uncertainty in different scientific disciplines and so because the assessment has to be based on other scientific publications this is not quite as simple as the IAC suggests.

"The key points in this report are that governments should now reform the IPCC management structure and that assessment of the science does need to meet very high standards because climate change has major implications."
