Symposium on Aerosols in Geoengineering; Portland, Oregon; October 26-30, 2010

这笔赠款支持一个关于气溶胶在地球工程中的潜在用途的研讨会。 地球工程是指故意修改地球系统，以抵消温室气体增加的变暖效应，本次研讨会将考虑与气溶胶注入大气层（通常是平流层）通过将阳光反射回太空来冷却地球的计划相关的前景，风险和不确定性。 研讨会将作为美国气溶胶研究协会年会的一部分举行（AAAR，2010年10月25日至29日举行），并有四个目标：1）加强两个社区之间的联系，2）评估影响气溶胶用于地球工程的科学不确定性，3）使气溶胶研究人员了解当前的地球工程研究，以及4）为地球工程研究人员提供关于气溶胶过程的反馈。研讨会要解决的一个主要问题是，正确的地球工程决策需要完全了解与每个地球工程计划相关的风险和利益。因此，重要的是气溶胶专家积极提高地球工程的整体理解。AAAR年会是气溶胶专家了解当前地球工程提案的理想场所。研讨会的知识价值在于进一步了解气溶胶-气候相互作用，而更广泛的影响包括：1）解决具有关键社会重要性的问题，2）促进两个科学界之间的合作，3）加强妇女参与科学，4）支持早期职业科学家。

This grant supports a symposium on the potential use of aerosols for geoengineering. Geoengineering refers to deliberate modification of the earth system to counteract the warming effect of greenhouse gas increases, and this symposium will consider the prospects, risks, and uncertainties associated with schemes in which aerosols are injected into the atmosphere (typically the stratosphere) to cool the planet by reflecting sunlight back to space. The symposium will take place as part of the annual meeting of the American Association for Aerosol Research (AAAR, held October 25-29 2010), and has four goals: 1) to strengthen connections between the two communities, 2) to evaluate scientific uncertainties that affect the use of aerosols for geoengineering, 3) to expose aerosol researchers to current geoengineering research, and 4) to generate feedback for geoengineering researchers on aerosol processes. A chief concern to be addressed by the symposium is that proper geoengineering decision making requires a complete understanding of the risks and benefits associated with each geoengineering scheme. Thus, it is important for aerosol experts to be active in improving the overall understanding of geoengineering. The AAAR annual meeting is an ideal venue for exposing aerosol experts to currentgeoengineering proposalsThe intellectual merit of the workshop lies in furthering understanding of aerosol-climate interactions,while the broader impacts include 1) addressing an issue of critical societal importance, 2) fostering collaboration between two scientific communities, 3) enhancing the participation of women in science, and 4) supporting early-career scientists.
