To co-produce or not to co-produce? A critical examinationof the translation of IPCC climate science into nationaladaptation policies

承诺到2050年实现净零排放，并将气温上升控制在1.5摄氏度以下，只会减少而不会阻止气候变化的影响。我们现在必须适应。需要了解哪些地方、哪些人会受到影响，以及应该采取什么措施。政府间气候变化专门委员会（IPCC）试图通过其评估报告做到这一点。自第一份报告发布以来的30年里，适应气候变化的进展仍然缓慢。目前还不清楚为什么一些国家的政策制定者未能实施有效的适应政策，而另一些国家却采取了雄心勃勃的适应政策。不作为通常是由于信息不能给决策者提供他们需要的东西。为了解决这个问题，IPCC越来越多地让科学家和政策制定者参与进来，共同开发气候科学，以提高该科学的可用性和使用。但是缺乏关于IPCC报告的有效性或如何用于为适应决策提供信息的数据。通过对官方文件和专家访谈的分析，本研究将为学者、从业者和政策制定者提供关于如何加速适应行动的重要见解。结合跨学科研究成果，该项目旨在：-了解IPCC的科学传播如何影响其在国家适应政策和决策中的使用-检查国家适应政策在不同国家的发展方式和原因-测试合作生产在提高气候科学在适应政策制定中的可用性和使用方面所发挥的作用。

Commitments to reach net-zero emissions by 2050, andkeep temperature rise below 1.5C, will only reduce, notstop the impacts of climate change. We must adapt now.Information is needed on where, and who, will be affectedand what should be done. The Intergovernmental Panel onClimate Change (IPCC) has sought to do this via itsAssessment Reports. Thirty years since the first report,progress on adaptation remains slow. It is unclear why some national policymakers fail toimplement effective adaptation policies whilst others adoptambitious ones. Inaction is often due to information failingto give decision-makers what they need. To resolve this,the IPCC increasingly involves scientists and policymakersto co-produce its climate science to improve the usabilityand use of that science. But there is a lack of data on theeffectiveness or how the IPCC reports are used to informadaptation decisions. Through an analysis of officialdocuments and expert interviews, this research will givescholars, practitioners, and policymakers crucial insightsinto how to accelerate adaptation action.Uniting cross-disciplinary findings, this project aims to: - Understand how the IPCC's communication of scienceshapes its use in national adaptation policies and decision-making- Examine how, and why, national adaptation policiesdevelop differently across countries- Test the role played by co-production in improving theusability and use of climate science in adaptationpolicymaking.
