Land Carbon

vulnerable-carbon-pools-gcp-2006The carbon cycle lies at the heart of Earth System Science, providing the key contribution to climatic-environmental changes by the redistribution of carbon between terrestrial, oceanic and atmospheric systems. Quantifying carbon fluxes, sources, sinks and stores, and understanding the nature of interactions and feedbacks are essential to climate change research and carbon management. However, the temporal patterns of the major carbon fluxes and their consequences for carbon stores are poorly understood at timescales greater than a few years.

This theme, therefore, provides the historical perspective to these issues, complementing the work of international programs like the Global Carbon Project (GCP).

The focus is on reconstruction of decadal-millennial carbon dynamics in anthropogenic and pre-anthropogenic systems, long-term changes in carbon stores, particularly through burial in lakes (Kortelainen et al., 2004; Downing et al., 2008) and terrestrial sediments, and spatial syntheses at regional to global scales.

This theme will overlap with the Water, Soil and Sediment, and Land Use and Cover themes.
