A group investigating the United Nations' Intergovernmental Panel on
Climate Change released a report Monday saying the IPCC needs to make several
changes to reduce errors and the chance of bias in its reports, including
fundamentally reforming its management structure.
The investigation by the InterAcademy Council, a consortium of national
academies of science, said the IPCC has been "successful overall" but
called for the widely watched organization to enforce its existing procedures
more strongly, and to ensure that "genuine controversies" about
climate science are reflected in the IPCC reports.
The IPCC also should establish an executive committee that includes people
outside the climate-science community, and it should limit the term of its
chairman to one term, the report said. The current limit of two six-year terms
for the chairman "is too long," the press release about the report
said.

Street Journal Web site, WSJ.com.)
The reforms would aid in seeing that "due consideration was given to
properly documented alternative views," according to a press release about
the report issued Monday morning.
In addition, the press release said, the IPCC's guidelines for dealing with
sources that aren't peer-reviewed are "too vague" and should be made
more specific to try to minimize errors from the use of such sources. The
report called on the IPCC to better characterize uncertainty in certain aspects
of climate science.
The report also called on the IPCC to develop a conflict-of-interest policy for
participants.
The investigation was requested by the IPCC in March, following the disclosure
of a handful of errors in the IPCC's 2007 climate-science report. Among the
errors was a projection that Himalayan glaciers would melt by 2035. The IPCC
later said that projection lacked scientific basis.
The 2007 IPCC report called climate change "unequivocal" and
"very likely" caused by human activity. The IPCC shared the 2007
Nobel Peace Prize with former Vice President Al Gore Jr. for its efforts on
promulgating information about climate change.
