英文摘要: | The Intergovernmental Panel on Climate Change reports provide the most reliable and robust assessment of understanding of the climate system. However, they do not include practitioner-based evidence, which is fundamental to make the reports a relevant source of information for decision-making.
The Intergovernmental Panel on Climate Change (IPCC) is increasing efforts to communicate its results more clearly to a wide audience in a way that limits confusion and increases their use. A clear example is offered by the 'headline statements' from the Summary for Policymakers of the Working Group I (WGI) contribution to the fifth assessment report (AR5)1, which summarizes the overarching conclusions. The IPCC WGI report provides the scientific evidence for international negotiations on mitigation targets, from which individual countries drive national policies and their own negotiating positions (Fig. 1). Increasingly, they are used by engineers, policymakers and other practitioners to develop climate change risk frameworks and vulnerability assessments.
