United States Representation in the International Arctic Science Committee (IASC): 2019-2023

北极对于理解地球系统至关重要，也是环境、经济、社会、人口和政治变化的焦点。它通过海洋、陆地和气团，以及居住在北极地区和/或与北极地区有经济联系的人，与全球系统密切相连。就北极正在发生的快速变化而言，这是一个前所未有的时代，我们理解、预测和应对这些变化的能力关系到美国和国际战略利益。没有一个国家能够支持跟上不断变化的北极所需的研究水平，因此，像国际北极科学委员会(IASC)这样的组织是讨论科学问题和促进国际、跨学科、在某些情况下在该地区开展大规模项目的重要平台。海冰融化对生物地球化学循环的影响、永久冻土融化和由此导致的碳循环变化、生物多样性和向北的物种迁徙和生态系统重组，以及相关的人类互动和反应，都将北极与全球系统联系在一起，是如此重要和如此巨大的问题，任何一个国家都不能孤立地充分解决这些问题。此外，经济发展、渔业、资源开采和旅游业的新机遇具有相对较高的风险，因为北极科学仍然相对不成熟。为此，该项目提供国家支持，以维持和加强美国在国际北极科学委员会的领导和伙伴关系，以及我们在国际舞台上的研究工作的规划和协调作用。国际北极科学委员会(IASC)是一个非政府的国际成员组织，鼓励和促进在北极研究的所有方面、所有参与北极研究的国家和北极地区所有地区的合作。国际会计准则理事会成立于1990年，目前有22个成员国。IASC是国际科学理事会(ICSU)的国际伙伴和北极理事会的观察员，并与许多其他国际北极组织有联系。美国是北极理事会的八个北极国家之一，IASC在为这个国际政策组织提供科学投入方面发挥了作用。机构间科学理事会通过为支持国际科学发展提供科学建议和协调来协助科学发展。自机构间科学理事会成立以来，北方的科学、环境、经济和政治现实发生了巨大变化。新的问题和挑战需要新的和改进的科学知识以及加强协调和沟通。这笔赠款提供资金，使IASC主席和IASC的美国代表能够实施IASC的活动和履行IASC的责任。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The Arctic is critical to understanding the Earth system, as well as a focal point for environmental, economic, social, demographic and political change. It is intimately connected to the global system via ocean, land, and air masses, as well as the people that inhabit and/or are connected economically to the Arctic region. This is an unprecedented time in terms of rapid changes occurring in the Arctic, and our abilities to understand, predict, and respond to those changes are of US and international strategic interest. No single country is able to support the level of research necessary to keep pace with the changing Arctic, and therefore organizations like the International Arctic Science Committee (IASC) represent vital platforms for discussing scientific issues and promoting international, interdisciplinary, and in some cases large-scale projects in the region. The impacts from melting sea ice on biogeochemical cycles, thawing permafrost and resulting change to the carbon cycle, biodiversity and northward species migration and ecosystem reorganization, and associated human interactions and response all link the Arctic to the global system and represent issues so important and so large that no one country can adequately address them in isolation. Additionally, new opportunities for economic development, fisheries, resource extraction and tourism carry a relatively high risk because Arctic science remains relatively immature. To this end, this project provides national support to maintain and enhance US leadership and partnerships in IASC, as well as our planning and coordinating roles for research efforts in the international arena.The International Arctic Science Committee (IASC) is a non-governmental international membership organization that encourages and facilitates cooperation in all aspects of Arctic research, in all countries engaged in Arctic research, and in all areas of the Arctic region. IASC was established in 1990 and today comprises twenty-two member countries. IASC is an international associate of the International Council for Science (ICSU) and an observer in the Arctic Council and has connections to numerous other international Arctic organizations. The US is one of eight Arctic nations in the Arctic Council, with IASC playing a role in providing scientific input to this international policy organization. IASC assists with science development by providing scientific advice as well as coordination to support international science development. Since the founding of IASC, the scientific, environmental, economic and political realities of the North have changed dramatically. New problems and challenges demand new and improved scientific knowledge and enhanced coordination and communications. This grant provides funds to enable the President of IASC and the US delegates to IASC to implement the activities and execute the responsibilities of IASC.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.
