Despite considerable uncertainties regarding the exact contribution of anthropogenic climate change to disaster risk, rising losses from extreme events have highlighted the need to comprehensively address climate-related risk. This requires linking climate adaptation to disaster risk management (DRM), leading to what has been broadly referred to as climate risk management (CRM). While this concept has received attention in debate, important gaps remain in terms of operationalizing it with applicable methods and tools for specific risks and decision-contexts. By developing and applying a methodological approach to CRM in the decision context of sovereign risk (flooding) in Austria we test the usefulness of CRM, and based on these insights, inform applications in other decision contexts. Our methodological approach builds on multiple lines of evidence and methods. These comprise of a broad stakeholder engagement process, empirical analysis of public budgets, and risk-focused economic modelling. We find that a CRM framework is able to inform instrumental as well as reflexive and participatory debate in practice. Due to the complex interaction of social–ecological systems with climate risks, and taking into account the likelihood of future contingent climate-related fiscal liabilities increasing substantially as a result of socioeconomic developments and climate change, we identify the need for advanced learning processes and iterative updates of CRM management plans. We suggest that strategies comprising a portfolio of policy measures to reduce and manage climate-related risks are particularly effective if they tailor individual instruments to the specific requirements of different risk layers.

实施气候风险管理的方法框架：管理奥地利与主权有关的与气候有关的极端事件风险。

尽管在人为气候变化对灾害风险的确切贡献方面存在很大的不确定性，但极端事件造成的损失不断增加，突显了需要全面解决与气候有关的风险。这就要求将气候适应与灾害风险管理（DRM）联系起来，从而导致广泛地称为气候风险管理（CRM）。尽管这一概念在辩论中受到关注，但在使用针对特定风险和决策环境的适用方法和工具对其进行操作方面，仍存在重大差距。通过在奥地利主权风险（洪水泛滥）的决策环境中开发和应用CRM的方法论方法，我们测试了CRM的有效性，并基于这些见解为其他决策环境提供了信息。我们的方法论方法基于多种证据和方法。这些包括广泛的利益相关者参与过程，对公共预算的实证分析以及以风险为中心的经济模型。我们发现，CRM框架能够在实践中为工具性，反思性和参与性辩论提供信息。由于社会生态系统与气候风险之间的复杂相互作用，并且考虑到由于社会经济发展和气候变化而导致与气候相关的未来或有的财政债务可能大幅增加的可能性，因此，我们确定了需要先进的学习过程和迭代方法CRM管理计划的更新。
