The COSMIC2 model provides climate-change impact modellers and policy analysts a flexible system
that can produce a full range of dynamic country-specific climate-change scenarios. The need for
this type of modeling capability was discussed at the IPCC Asia-Pacific Workshop on Integrated
Assessment Models held in Tokyo in 1997. That Workshop aimed at improving communication between
experts in a variety of disciplines and policy analysts/policy makers. One goal was to expand the
use of integrated-assessment modelling for addressing the potential impacts of climate change in a
way that better reflected the experiences of researchers from developing countries.
These researchers (and others at universities around the world) may not have access to
state-of-the-art transient general circulation model (GCM) simulations. The expense of running
these supercomputer models limits their availability and ease of use. The COSMIC2 model helps
remove this limitation. COSMIC2 can provide easy access to credible climate-change scenarios that
are consistent with the state-of-the-art, fully coupled, transient ocean-atmosphere GCM
