Percent change in above ground tree cover for the Amazon Basin under GISS climate scenario and no deforestation with fire (2080s)

The integrity of Amazon forests are currently threatened by climate change, deforestation, and fire. However, it is unclear how these agents of change interact over large spatial and temporal domains and reducing this uncertainty is important for projecting changes in carbon stocks and species biogeography, and could better inform continental scale conservation programs. With this in mind, above ground biomass and tree cover data were produced using the dynamic global vegetation model, LPJmL, with 9 different global climate models (using the SRES A2 emissions storyline) and 2 different deforestation scenarios (from Soares et al.). The existing fire module was modified to include 'escaped fire' associated with deforestation, and included feedbacks from climate change as temperatures warm and litter moisture decreases. The data presented here include control simulations (i.e., no climate change, no deforestation, and no fire) to provide baselines for comparing with projected global change influences. In total, 10 climate scenarios, 6 deforestation and fire scenarios, and 5 time slices are presentation (n = 300) for above ground biomass and tree cover.
