近日，美国密歇根大学Maria Carmen Lemos团队报道了扩大可操作的气候知识。该项研究成果发表在2025年11月26日出版的《美国科学院院刊》杂志上。

为应对气候驱动的危机，学界需要可操作的气候知识来指导决策并助力问题解决。尽管可操作知识的科学体系正在快速发展，但关于可操作性气候知识如何及为何能实现规模化推广、其成效如何等问题仍待探索。

研究组提出三种以成果为导向的可操作性气候知识规模化路径：1）通过增加参与气候知识协同生产主体的多样性与数量来扩大参与范围；2）推动未参与初始协同生产的群体接纳应用此类知识；3）与具有广泛影响力的实践者及政策制定者等关键主体协同生产，以凝聚规模效应。这些路径既可相互交织、补充促进，也可能存在相互作用与制约。若想更好地指导气候行动知识的规模化生产与推广以解决气候问题，深入理解这些路径的运行机制、演进规律与动态变化至关重要。

Abstract: To address climate-driven crises, we need actionable climate knowledge to inform decision-making and support problem solving. Although the science of actionable knowledge is rapidly evolving, less is known about how and why actionable climate knowledge scales up and with what outcomes. We advance three outcome-driven pathways to scale up actionable climate knowledge: 1) broadening participation by increasing the diversity and number of actors involved in actionable climate knowledge coproduction; 2) diffusing actionable climate knowledge uptake among actors not originally involved in its coproduction, and 3) aggregating impact by coproducing actionable climate knowledge with influential actors, such as practitioners and policy-makers, whose decisions affect many others. These pathways can intersect, complement, interact, and tradeoff with each other. Understanding how these pathways work, evolve, and change is critical if we want to better inform the production and scaling of climate actionable knowledge to solve climate problems.
