Newest CCSM3 Animation shows Four IPCC Scenarios

CGD the CCSM Community have released an updated CCSM3 animation that models global warming up to the year 2100 in each of the four IPCC Fourth Assessment Report scenarios for CO2 levels. Entitled, "Surface temperature change relative to 1879 - 1899 baseline," the model shows the temporary cooling effects during the 5 major volcanic eruptions of this time period, and then the model's estimates of warming under the different scenarios.

December 2006: CGD's Jeff Kiehl and Christine Shields were awarded UCAR's Outstanding Publication Award for 2006 for their paper titled "Climate Simulation of the Latest Permian: Implications for Mass Extinction". This paper models the climate of the Permian Era using the CCSM3. The paper has been published in "Geology", volume 33, and is available on the web.

December 2006: Marika Holland, Cecilia Bitz, and Bruno Tremblay's 2006 AGU paper titled "Future Abrupt Reductions in the Summer Arctic Sea Ice" has been getting quite a bit of attention in the media. This study use the future climate scenario runs of the CCSM3 to predict changes in Arctic sea ice. The full paper is available on the web. You may also enjoy a short video highlight from Marika's presentation, recent press release, and a BBC News article.

CESM Project

The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.

CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR).
