Collaborative proposal: Workshop on ecological impacts of solar radiation management geoengineering; February , 2020; Port Jefferson, NY; October, 2020, Minneapolis, MN

这个研讨会奖将讨论环境地球工程对地球生命系统的影响。地球工程是一系列旨在对抗环境变化影响的活动。由于未能限制温室气体向大气的排放，它受到了越来越多的关注。这些观点在科学家和公众中都有很大的争议。尽管如此，已经提出了许多地球工程方案，其中一些方案已经使用复杂的气候模型进行了广泛的研究。地球工程中研究得最好的方案是太阳辐射管理，它将通过增加地球-大气系统的反射率（反射率）来冷却地球表面，减少入射的太阳辐射。这种地球工程管理方案给自然生物世界带来了已知和未知的风险。然而，关于实施、延续或终止对自然系统、其功能及其生物多样性的潜在影响，我们几乎一无所知。讲习班的目标是制定一个研究议程，以了解和预测自然系统的生物多样性和功能将如何受到太阳辐射管理的影响。讲习班将开发信息，为政策和公众讨论提供信息，提供知识，将其纳入教学和外展活动，并让不同的听众参与讨论生命系统对太阳辐射地球工程的反应。这个研讨会奖项的一个主要目标是建立一个框架，使人们能够理解和预测自然系统的生物多样性和功能如何受到太阳辐射地球工程的影响。尽管越来越多的文献对管理具有行星尺度影响的不确定过程持谨慎态度和策略，但关于地球工程对生态系统的影响的研究很少甚至没有。研讨会将讨论这种地球工程方法如何改变环境变化对自然系统的预测影响。讲习班的一项主要成果将是一项研究议程，其中将列出关于生态影响研究的一系列高度优先问题，考虑这些挑战并讨论如何应对这些挑战，并为更广泛的有关科学界发起和宣传一项研究议程。这些问题包括：缩小尺度，估计生物多样性热点地区或疑似范围限制/扩展的关键地点的植物、鸟类和两栖动物的多样性，并将这些数据与地球工程情景的气候预测联系起来。该研讨会将支持一组生态学家和气候科学家的合作，从研究生到高级学术和联邦实验室研究人员，以制定关于这种地球工程方法的生态影响的研究议程。他们将研究自然系统如何受到气候变化的影响，并与未来人为环境变化进行对比。拟议的讲习班将包括两次面对面会议和面对面会议之前、期间和之后的定期电子会议。这个高度跨学科专业的合作团队将由大气科学家和研究广泛生态领域的科学家组成，包括来自其他学科的研究人员，以促进该领域的未来研究。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This workshop award will address the impacts of environmental geoengineering on the living systems of earth. Geoengineering is a set of activities deliberately designed to counter the impacts of environmental change. It has received increasing attention in the face of failure to limit inputs of greenhouse gases to the atmosphere. These ideas are highly controversial among both scientists and the general public. Nevertheless, many schemes for geoengineering have been proposed and some have been extensively studied using complex climate models. The best-studied scheme for geoengineering is solar radiation management, which would cool Earth's surface by increasing the albedo (reflectivity) of the Earth-atmosphere system, reducing incoming solar radiation. This geoengineering management option presents both known and unknown risks to the natural living world. Yet almost nothing is known about the potential impacts of implementation, continuation or termination on natural systems, their functions, and their biodiversity. The goal of the workshop is to develop a research agenda to understand and predict how the biodiversity and functioning of natural systems would be affected by solar radiation management. The workshop will develop information to inform policy and public discussion, provide knowledge to incorporate into teaching and outreach, and engage a diverse audience in discussions on the response of living systems to solar radiation geoengineering.A major goal of this workshop award is to develop a framework that will enable understanding and predictions of how the biodiversity and functioning of natural systems would be affected by solar radiation geoengineering. Despite the growing literature of caution and strategies for managing an uncertain process with planetary-scale implications, there has been little to no research on the implications of geoengineering for ecological systems. The workshop will address how this geoengineering approach could change predicted effects of environmental change on natural systems. A major product of the workshop will be a research agenda that will lay out a series of high priority issues for research on ecological impacts, consider the challenges and discuss how they might be met, and initiate and publicize a research agenda for the wider relevant scientific communities. Such issues include: downscaling, estimating diversity for plants, birds, and amphibians in biodiversity hotspots or at critical sites for suspected range limitations/expansions, and connecting those data with climate projections for geoengineering scenarios. The workshop will support the collaboration of a group of ecologists and climate scientists, ranging from graduate students to senior academic and federal laboratory researchers, to develop a research agenda on the ecological impacts of this geoengineering approach. They will examine how natural systems would be impacted by the climate modification, in contrast to future anthropogenic environmental change. The proposed workshop would consist of two in-person meetings and regular electronic meetings before, during and after the in-person meetings. This collaborative team of highly interdisciplinary specialties will consist of atmospheric scientists and scientists studying a wide range of ecological areas, including researchers from additional disciplines to contribute to future research in this area.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.
