项目摘要
The most recent IPCC working group report declared that observed climate changes are "unprecedented" and "intensifying" and the United Nations declared that tackling the scientific understanding of climate change as "one of the most pressing issues of our time". In the Canadian context, climate change impacts in the Arctic are explicitly linked with economic prosperity, resource security, and National sovereignty, including transportation routes and international trade via northern shipping routes and ice roads. Runoff generation and cumulative contributions of freshwater discharge into the Arctic basin are rapidly changing under warming high-latitude climates, but the impacts of these dynamic shifts in both the timing and volume of freshwater are relatively unknown. It is well established that increasing freshwater discharge to the Arctic basin is impacting the amount and seasonality of sea ice, which in turn influences thermohaline circulation. Examining the influence changing freshwater inputs have on the Arctic basin is crucial to the global understanding of climate change and Arctic ecosystems. Leveraging my expertise in continental scale, high latitude hydrologic modelling, this research proposes to develop critical linkages between climate, hydrologic and human-induced landscape changes that impact pan-Arctic discharge. By developing an integrated pan-arctic System Modelling (PASM) platform, dynamic climate-driven hydrologic scenarios will be integrated with the NEMO ocean model, providing continuous (in time and space) runoff, physical tracers of freshwater (i.e., temperature, isotope tracers), and river ice and velocity. Such a platform is crucial to the understanding of the cumulative effects of climate change on Arctic systems, and the subsequent impacts on ocean thermohaline circulation (i.e., the North Atlantic deep-water formation) affecting global climate. The Intergovernmetal Panel on Climate Change and Arctic council both recognize the Grand Challenge of an Arctic region at risk under a rapidly warming climate, destabilizing soils underpinning infrastructure and impacting transportation and access to the North.
政府间气候变化专门委员会最近的工作组报告宣布,观察到的气候变化是“前所未有的”和“加剧的”,联合国宣布,解决气候变化的科学理解是“我们这个时代最紧迫的问题之一”。在加拿大的背景下,北极地区的气候变化影响与经济繁荣、资源安全和国家主权明确相关,包括通过北方航线和冰路的运输路线和国际贸易。在高纬度气候变暖的情况下,流入北极盆地的淡水的径流量和累积贡献正在迅速变化,但淡水的时间和数量的这些动态变化的影响相对未知。众所周知,越来越多的淡水流入北极盆地,影响着海冰的数量和季节性,这反过来又影响着温盐环流。研究不断变化的淡水输入对北极盆地的影响对于全球了解气候变化和北极生态系统至关重要。利用我在大陆尺度,高纬度水文建模的专业知识,这项研究提出了发展气候,水文和人类引起的景观变化,影响泛北极排放之间的关键联系。通过开发一个综合的泛北极系统建模(PASM)平台,动态气候驱动的水文情景将与NEMO海洋模型相结合,提供连续的(在时间和空间上)径流,淡水的物理示踪剂(即,温度,同位素示踪剂),河冰和速度。这样一个平台对于了解气候变化对北极系统的累积影响以及随后对海洋温盐环流的影响(即,北大西洋深水层)影响全球气候。政府间气候变化专门委员会和北极理事会都认识到北极地区在迅速变暖的气候下面临的巨大挑战,这将破坏基础设施的土壤稳定,影响运输和通往北方的通道。
