This guide aims to make the findings of the Intergovernmental Panel on Climate Change's special report on the ‘impacts of global warming of 1.5°C global greenhouse gas emission pathways' accessible to humanitarian and development practitioners and policy-makers working at global and regional scale. It provides an interpretation of the findings with a focus on the adaptation implications of the Special Report. The guide synthesises information from the report, adds case studies to illustrate key messages and points readers to additional resources where they can obtain more information. The guide begins with a basic overview of the feasibility of limiting warming to 1.5°C, and what it would take to do this. Based on this background, it then outlines the impacts associated with 1.5°C and greater warming. This section includes possible risk hotspots, trends, and tipping points. This is followed by a section on sectoral impacts in order to inform readers on how the risks associated with warming are projected to manifest. In the context of the mitigation findings, the guide goes on to explain the adaptation implications of the report, including guidance on implementing adaptation as well as areas that need to be strengthened.
