Climate change impacts in the Hudson Bay region

哈德逊湾地区特别容易受到气候变暖的影响。海冰的分布和持续时间是区域气候的关键驱动因素。过去的研究表明，海冰正在消失，并将继续消失，甚至在下个世纪内几乎将消失。这一地区已被确定为世界上对气候变化最敏感的地区之一，气候变化导致了截然不同的气候。这对该地区的自然地理、生物群和人类人口具有广泛的影响。这项研究涉及的研究目标是：1)将海冰记录延长到1969年以前的几十年(和卫星侦察)，使用温度变率作为替代；2)使用科学状况耦合气候模型和现有的缩小尺度技术更新该区域的气候变化预测；3)评估气候变化对哈德逊湾及周边地区原住民和因纽特人社区的自然环境和人类基础设施的影响，这项研究的成功完成将为哈德逊湾地区的气候变化影响评估提供基本要素，并使其能够更好地为当地人口制定必要的适应战略。

The Hudson Bay region is particularly susceptible to the effects of a warming climate. Sea ice distribution and duration is a key driver of the regional climate. Past research has indicated that sea ice is both disappearing and will continue to disappear and will virtually disappear within the next century. This area has been identified as one of the most sensitive regions in the world to climate change which result in a dramatically different climate. This has broad implications on the physical geography, biota and human populations of the region. The research objectives addressed in this research are, 1) the extension of the sea ice record to the decades before 1969 (and satellite reconnaissance) using temperature variability as a proxy, 2) the updating of the climate change projections for the region using state of the science coupled climate models and available downscaling techniques and 3) the assessment of impacts of climate change on the physical environment and human infrastructure of the First Nations and Inuit communities in the Hudson Bay and surrounding areas, focussing on food security and transportation safety.The successful completion of this research will provide the essential elements of a climate change impact assessment of the Hudson Bay region and enable better preparation for necessary adaptive strategies for local populations.
