The aim of this project was to bring together a range of work to examine the global impacts of climate change at different degrees of temperature rise (up to 5°C where possible), identifying vulnerable sectors in different parts of the world. The project aims to analyse impacts work in a consistent way, explicitly identifying assumptions between different results, and provides a basis for comparison with how impacts are handled in integrated assessment models. A key output of the project is the set of impacts matrices accompanying this report showing impacts in various sectors and regions. All annual global mean temperature increases mentioned in this report refer to a baseline date of 1990.
