Amazonian Deforestation and Climate describes the results from ABRACOS, the Anglo-Brazilian Amazonian Climate Observation Study. ABRACOS was a major collaboration between British and Brazilian scientists with the objective of quantifying the changes to the water and carbon cycles, and the interaction between the soil, vegetation and atmosphere which occurs when the primary rainforest is removed and replaced with cattle ranchland. The book analyses the measurements taken in the pasture and rainforest at a series of sites across Amazonia. These measurements are entered into the Global Circulation Models which are used to predict the climate effects of large scale deforestation. Results are presented at all scales, from the centimetre scale of leaf and soil moisture measurements to the field scale of micrometeorological flux measurements, through the scale of meteorological models which predict the climate of the whole Amazonian Basin.
