Projected warming through the next century will be most strongly expressed at high latitudes. These areas are amongst the most sensitive to environmental change and play an important role in the global climate system. However, future trajectories of Arctic systems are poorly known. The purpose of this research is to establish robust archives of past Arctic dynamics from geologic records that span climate intervals as warm or warmer than present, and provide a roadmap for future changes. This research builds on the established program by the applicant in northwestern Canada and Alaska.

预计下个世纪的变暖将在高纬度地区表现得最为强烈。这些地区是对环境变化最敏感的地区之一，在全球气候系统中发挥着重要作用。 然而，人们对北极系统的未来轨迹知之甚少。 这项研究的目的是根据跨越比现在温暖或更温暖的气候区间的地质记录，建立过去北极动态的可靠档案，并为未来的变化提供路线图。这项研究建立在申请人在加拿大西北部和阿拉斯加制定的计划的基础上。
