The CCSM Community have released an updated model of 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.


Community Climate System Model

CCSM belongs to an elite category of computer-based simulation models known as general-circulation models. Such models use mathematical formulas to recreate the chemical and physical processes that drive Earth's climate. What emerges from trillions of computer calculations is a picture of the world's climate in all its complexity. The Ocean Model Working Group was formed to discuss issues related to ocean components in the CCSM context and to coordinate the development and testing of ocean components.
