Synopsis: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 186.Amazonia and Global Change synthesizes results of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) for scientists and students of Earth system science and global environmental change. LBA, led by Brazil, asks how Amazonia currently functions in the global climate and biogeochemical systems and how the functioning of Amazonia will respond to the combined pressures of climate and land use change, such asWet season and dry season aerosol concentrations and their effects on diffuse radiation and photosynthesisIncreasing greenhouse gas concentration, deforestation, widespread biomass burning and changes in the Amazonian water cycleDrought effects and simulated drought through rainfall exclusion experimentsThe net flux of carbon between Amazonia and the atmosphereFloodplains as an important regulator of the basin carbon balance including serving as a major source of methane to the troposphereThe impact of the likely increased profitability of cattle ranching.The book will serve a broad community of scientists and policy makers interested in global change and environmental issues with high-quality scientific syntheses accessible to nonspecialists in a wide community of social scientists, ecologists, atmospheric chemists, climatologists, and hydrologists.
