The contribution of the Community Climate System Model (CCSM3) to the 4th Assessment Report of the Intergovernmental Panel on Climate Change
June 7, 2007
The talk centers around how the careful preparation, sheer scope of the runs and depth/quality of the scientific analysis of the IPCC AR4 has resulted in a broad acceptance of findings of the report in the government, industry, and public sectors. A major theme will be highlighting the success of the DOE/NSF climate collaboration and acknowledgment of NERSC/LBL's critical role in the CCSM development, production and data distribution (we were the largest data contributor to the IPCC AR4 of any modeling group on the planet) for the AR4. The take away message is that the IPCC AR4 should be considered a major scientific breakthrough in that it is fundamentally changing the research landscape in climate sciences. The broad acceptance of the AR4 results is allowing climate researchers to
finally move beyond our traditional set of historical and future business-as-usual simulations (a terascale problem) and begin researching a wide range of adaptation and mitigation response options (a petascale problem requiring a much broader range of collaborations).
