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

北极是了解地球系统的关键，也是环境、经济、社会、人口和政治变革的焦点。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们，它与全球系统密切相连。就北极地区正在发生的快速变化而言，这是一个前所未有的时期，我们理解、预测和应对这些变化的能力关系到美国和国际的战略利益。没有一个国家能够支持跟上北极变化所需的研究水平，因此，像国际北极科学委员会（IASC）这样的组织代表了讨论科学问题和促进该地区国际、跨学科和某些情况下大型项目的重要平台。海冰融化对生物地球化学循环的影响、永久冻土融化以及由此导致的碳循环变化、生物多样性和向北物种迁移和生态系统重组，以及相关的人类相互作用和反应，都将北极与全球系统联系在一起，这些问题如此重要和巨大，任何一个国家都无法单独妥善解决。此外，由于北极科学仍相对不成熟，经济发展、渔业、资源开采和旅游业的新机遇面临着相对较高的风险。为此，该项目提供国家支持，以维持和加强美国在机构间常设委员会中的领导地位和伙伴关系，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，鼓励和促进北极研究的各个方面、从事北极研究的所有国家和北极地区的所有领域的合作。机构间常设委员会成立于1990年，目前由22个成员国组成。IASC是国际科学理事会（ICSU）的国际合作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着作用。机构间常设委员会通过提供科学建议和协调来支持国际科学发展，从而协助科学发展。自机构间常设委员会成立以来，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，需要加强协调和沟通。这笔赠款提供资金，使机构间常设委员会主席和美国驻机构间常设委员会代表能够实施机构间常设委员会的活动并履行其职责。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。

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.
