United States Climate Change Science Program

    The United States Climate Change Science Program requests expert 
review of the Working Group II contribution (``Climate Change 2007: 
Impacts, Adaptation, and Vulnerability'') to the Intergovernmental 
Panel on Climate Change Fourth Assessment Report.
    The Intergovernmental Panel on Climate Change (IPCC) was 
established by the United Nations Environment Programme (UNEP) and the 
World Meteorological Organization (WMO) in 1988. In accordance with its 
mandate and as reaffirmed in various decisions by the Panel, the major 
activity of the IPCC is to prepare comprehensive and up-to-date 
assessments of policy-relevant scientific, technical, and socio-
economic information relevant for understanding the scientific basis of 
climate change, potential impacts, and options for mitigation and 
adaptation. The First Assessment Report was completed in 1990, the 
Second Assessment Report in 1995, and the Third Assessment Report in 
2001. Three working group volumes and a synthesis report comprise the 
Fourth Assessment Report, with all to be finalized in 2007. Working 
Group I assesses the scientific

aspects of the climate system and climate change; Working Group II 
assesses the vulnerability of socio-economic and natural systems to 
climate change, potential negative and positive consequences, and 
options for adapting to it; and Working Group III assesses options for 
limiting greenhouse gas emissions and otherwise mitigating climate 
change. These assessments are based upon the peer-reviewed literature 
and are characterized by an extensive and open review process involving 
both scientific/technical experts and governments before being accepted 
by the IPCC.
    The IPCC Secretariat has informed the U.S. Department of State that 
the second-order draft of the Working Group II contribution to the 
Fourth Assessment Report is available for Expert and Government Review. 
The Climate Change Science Program Office (CCSPO) is coordinating 
collection of U.S. expert comments and the review of these collations 
by panels of Federal scientists and program managers to develop a 
consolidated U.S. Government submission. Instructions on how to format 
comments are available at http://www.climatescience.gov/Library/ipcc/wg24ar-review.htm
, as is the document itself and other supporting 

materials. Comments must be sent to CCSPO by June 28, 2006 to be 
considered for inclusion in the U.S. Government collation. Comments 
submitted for potential inclusion or consideration as part of the U.S. 
Government Review should be reserved for that purpose, and not also 
sent to the IPCC Working Group II Technical Support Unit as a discrete 
set of expert comments.
    Properly formatted comments should be sent to CCSPO at 
wg24AR-USGreview@climatescience.gov by COB Tuesday, June 28, 2006. Include 

report acronym and reviewer surname in e-mail subject title to 
facilitate processing.

Change Science Program, Suite 250, 1717 Pennsylvania Ave., NW.,
