Community Climate System Model
|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
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.
