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.

在北半球中部纬度的过去气候变异性的高分辨率记录中存在关键的差距，特别是记录跨越快速变暖事件的记录。该提议解决了以下假设：在快速变暖的事件中，定义为每世纪的几个变暖，北半球中半纬度的净夏季降水量下降，而冬季降水量增加，无论边界条件如何。该假设基于该地区气候的未来情况，但是这些外国人的不确定性很大。研究人员将通过审查和采用一种使用生物标志物和稳定的氢在湖沉积物中的生物标志物和稳定的同位素来重建温度，精密季节性和夏季净精度的方法来检验假设并填补这些空白之一。由此产生的高分辨率记录将跨越过去15，000年中的三个最大的变暖事件，每个事件发生在不同的边界条件下，以及最近的500年。 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 divers undergraduate and graduate students (University at Buffalo, NY) for Science, Technology, Engineering, and Math (STEM) careers by training them to understand and communicate climate社会文化相关环境中的科学并解决复杂的问题。该课程和实习重点是一个现实世界中的项目，在该项目中，学生与当地企业合作，并利用科学研究作为为这些业务制定碳足迹和战略气候行动计划的基础。该计划还将解决教育研究问题，来自不同社会文化背景的学生如何理解和传达有关复杂系统的知识，以及基于项目的课程的最爱中的哪些方面？通过检查对北半球突然气候变化的降水响应，该项目将培训2个研究生和5年级的研究生和经济范围，以适用于适当的范围，以适用于北半球的突然气候变化。此外，学生将直接将研究结果转化为企业可以用来降低碳足迹并建立弹性的战略计划。为企业开发的框架将被公开可用，并通过区域业务网络传播。该彻底审查的课程将用于培训75名不同的学生从事STEM职业，并将被其他教育提供。该项目的研究和教育方面强调了地球科学中人数不足的学生的招聘和保留。该奖项反映了NSF的法定使命，并使用基金会的知识分子优点和更广泛的影响审查标准，认为通过评估被认为是珍贵的支持。
