Four alternative future scenarios for the Great Barrier Reef to 2050 under moderate (1a and 1b) and extreme (2a and 2b) climate change, and limited (1a and 2a) and ideal (1b and 2b) adaptation. The scenarios reflect key differences in run-off from the catchment and water quality, coral cover and composition, mangrove erosion and distributional change, fish abundance (illustrated by coral trout and barramundi) and social adaptation in the fishing and tourism industries.
