11. CCSP Workshop • Location: Marriott Crystal Gateway, Arlington, VA • Purpose: To facilitate exchange of ideas among the government, academic, international, NGO, and stakeholder groups participating in the CCSP process. • Topics: Discussions will include the scientific basis and the use of the CCSP Synthesis and Assessment Products in addressing CCSP’s three decision support goals: • Prepare scientific syntheses and assessments (national and international) • Develop and illustrate adaptive management and planning capabilities. • Develop and evaluate methods to support climate change policy inquiries • Registration: http://www.climatescience.gov/workshop2005/ OFCM/CCAMS Meeting – May 3, 2005

12. IPCC Fourth Assessment Report • U.S. Models • CCSM3, PCM, GFDL (2 versions), and GISS (3 versions). • All are coupled ocean/atmosphere/land models • New model development: US models include 2nd highest resolution in the international effort • Ensemble simulations to characterize uncertainty All simulations available to the modeling community through PCMDI, and a subset of data for impacts researchers through IPCC TGICA • CCSP role • Funding provided to participating community • Support for meetings to review model results • Papers in preparation to meet AR4 publication deadline • Support for WG I TSU and participation of US scientists OFCM/CCAMS Meeting – May 3, 2005
