This report documents the approach and results of defining regional climate change scenarios for the LMB. Chapter 2 describes the findings of CCAI (2015)’s reviewing of international approaches in defining climate change scenarios. Chapter 3 describes the approach and points of considerations for defining climate change scenarios for the LMB as recommended from the review. Chapter 4 explains the needs and criteria to select and obtain a climate change projection data set to be used in the scenarios development process. Then Chapters 5 and 6 present the approach and results of defining a number of climate change scenarios for the region including GCM shortlisting, GCM selection, sensitivity analysis of emission scenarios and climate sensitivity settings, and recommendation of a number of climate change scenarios. Finally, Chapter 7 documents the strengths and weaknesses of the approach being used and makes recommendations for any future work that is required.
