DOE’s Integrated Assessment (IA) of Climate Change Research Program combines simplified representations of the entire global climate system, emphasizing greenhouse gas (GHG) emissions and actions that would affect emissions. Integrated models are used to assess the value of technologies that result from research; these include new biotechnological approaches, for example, that improve biomass conversion and generate hydrogen, an expected result of the knowledgebase generated in the GTL program. IA research provides a foundation for subsequent policy analysis or decision making.
The IA Program addresses several of DOE’s research priorities. The most immediate issue of interest is the role of energy production and associated GHG emissions in global climate change. Closely related is the question of climate change impacts—by extension, energy production impacts—on humans and their environment. The program thus brings together a major approach (integrated assessment), a global environmental problem (climate change), and the scientific challenges of interdisciplinary and modeling of multiscale complex systems.
