The impact of future climate change on glaciated regions of the world (both high altitude and high latitude) has important ramifications for the availability of freshwater. Sectors highly dependent on sustained and robust levels of glacial/snow meltwater during the summer melt season include agriculture, hydroelectric power production, and public availability of freshwater. Other related factors dependent on Earth’s glaciers include global sea level, the geopolitics of trans-border river flows, and the dangers of Glacial Lake Outburst Floods (GLOFs). In certain regions of the world (for example, the countries spanned by the Himalaya) glacial meltwater is the primary source of freshwater yet GLOFs have been on the increase in the Himalaya, the Alps, and the Andes, killing thousands of people and causing millions of dollars in damage to settlements, infrastructure, and livestock. I plan to focus the research outlined below on two sensitive regions of the globe: western Canada (British Columbia and Alberta) and the Himalaya (Pakistan, India, and Nepal).

未来气候变化对世界冰川地区（高海拔和高纬度地区）的影响对淡水的供应具有重要影响。在夏季融化季节，高度依赖持续和强劲的冰川/雪融水的部门包括农业，水力发电和公共淡水供应。其他与地球冰川相关的因素包括全球海平面、跨境河流的地缘政治以及冰川湖爆发洪水（GLOFs）的危险。在世界上的某些地区（例如，喜马拉雅山脉跨越的国家），冰川融水是淡水的主要来源，但在喜马拉雅山脉、阿尔卑斯山和安第斯山脉，冰川融水一直在增加，造成数千人死亡，并对定居点、基础设施和牲畜造成数百万美元的损失。我计划把下面概述的研究重点放在地球仪的两个敏感地区：加拿大西部（不列颠哥伦比亚省和阿尔伯塔）和喜马拉雅山（巴基斯坦、印度和尼泊尔）。
