The document describes Project Phoenix, a project to develop an integrated assessment model to analyze global warming impacts, mitigation, and adaptation. The model will be multi-region and multi-sector, and include an economic model integrated with an energy flow model. It will assess climate change impacts on areas like food and water resources. The project will develop scenarios using a cross-impact method to consistently incorporate key social and technological factors. Preliminary model simulations assess economic impacts of carbon emission policies under different scenarios.
