Scales and Processes of the Global Carbon Cycle

view full-size image

The global carbon cycle is determined by the interactions of climate, the environment, and Earth’s living systems at many levels, from molecular to global. Relating processes, phenomena, and properties across spatial and temporal scales is critical for deriving a predictive mechanistic understanding of the global carbon cycle to support more precise projections of climate change and its impacts. Each domain of climate, ecosystem, and molecular biology research has a limited reach in scales, constrained by the complexity of these systems and limitations in empirical and modeling capabilities. While comprehensive linkage of genomes to global phenomena is intractable, many insightful connections at intermediate scales are viable with integrated application of new systems biology approaches and powerful analytical and modeling techniques at the physiological and ecosystem levels. Biological responses (blue) are to the right of the systems ovals, and climate and environmental factors (green) are to the left of the systems ovals.
