There are critical gaps in high-resolution records of past climate variability in Northern Hemisphere mid-latitudes, specifically records spanning rapid warming events. This proposal addresses the hypothesis that during rapid warming events, defined as several °C of warming per century, Northern Hemisphere mid-latitude net summer precipitation decreases, and winter precipitation increases, regardless of boundary conditions. This hypothesis is based on future scenarios for climate in this region, but these forecasts have large uncertainties. The researcher will test the hypothesis and fill one of these gaps by vetting and applying an approach that uses biomarkers and stable isotopes of Hydrogen in lake sediments to reconstruct temperature, precipitation seasonality, and net summer precipitation in the Laurentian Great Lakes region. The resulting high-resolution records will span the three largest warming events in the past 15,000 years, each of which occurred under different boundary conditions, and the most recent 500 years. This research will further test the hypothesis throughout the Northern Hemisphere mid-latitudes using a paleoclimate database spanning the past 15,000 years, which will be improved and expanded as part of the project.The research will be integrated into an education program (course and summer internship) that prepares diverse undergraduate and graduate students (University at Buffalo, NY) for Science, Technology, Engineering, and Math (STEM) careers by training them to understand and communicate climate science in socio-culturally relevant contexts and to solve complex problems. The course and internship focus on a real-world project in which students partner with local businesses and use scientific research as the basis to develop carbon footprints and strategic climate action plans for these businesses. This program will also address the educational research question, how do students from different socio-cultural contexts understand and communicate knowledge about complex systems, and what aspects of the project-based curriculum facilitate this communication?By examining the precipitation response to abrupt climate change in the Northern Hemisphere mid-latitudes, this project will train 2 graduate and 5 undergraduate research students and will provide information for adaptation measures in a highly populated and economically important region. Furthermore, students will directly translate research results into strategic plans that businesses can use to reduce their carbon footprint and build resiliency. The framework developed for businesses will be made publicly available and disseminated through regional business networks. This thoroughly vetted curriculum will be used to train 75 diverse students for STEM careers and will be made available for use by other educators. The research and education aspects of this project emphasize recruitment and retention of students underrepresented in Geosciences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

北半球中纬度地区过去气候变化的高分辨率记录存在重大差距，特别是跨越快速变暖事件的记录。该提案提出了这样的假设：在快速变暖事件（定义为每世纪变暖几摄氏度）期间，北半球。无论边界条件如何，中纬度夏季净降水量都会减少，而冬季降水量会增加。该假设是基于该地区未来的气候情景，但这些预测具有很大的不确定性。研究人员将检验该假设并填补其中一个空白。通过审查和应用利用湖泊沉积物中氢的生物标记物和稳定同位素的方法来重建劳伦森五大湖地区的温度、降水季节性和夏季净降水，由此产生的高分辨率记录将涵盖过去 15,000 年中三个最大的变暖事件。 ，每一个都发生在不同的边界条件下，并且最近 500 年的研究将使用跨越过去的古气候数据库进一步检验整个北半球中纬度地区的假设。 15,000 年，将作为该项目的一部分进行改进和扩展。该研究将被纳入教育计划（课程和暑期实习）中，为不同的本科生和研究生（纽约州布法罗大学）的科学、技术、工程做好准备和数学（STEM）职业，培训他们在社会文化相关背景下理解和交流气候科学，并解决复杂的问题。该课程和实习重点关注学生与当地企业合作并利用科学研究的现实项目。作为开发碳的基础该计划还将解决这些企业的足迹和战略气候行动计划，即来自不同社会文化背景的学生如何理解和交流有关复杂系统的知识，以及基于项目的课程的哪些方面促进了这种交流？通过研究北半球中纬度地区降水对气候突变的响应，该项目将培训 2 名研究生和 5 名本科生，并为人口稠密和经济重要地区的适应措施提供信息。此外，学生将直接进行翻译。研究成果转化为企业可以使用的战略计划为企业开发的框架将通过区域商业网络公开和传播，该课程将用于培训 75 名不同的学生进行 STEM 职业，并可供其他人使用。该项目的研究和教育方面强调招募和保留地球科学领域代表性不足的学生。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
