Far-flung influences on midlatitude weather and climate: The stratospheric pathway
… the response of the polar vortex to projected Arctic climate change, in terms of both the mean state and variability, before focusing on the impact of sudden stratospheric warmings (SSWs) on European energy demand. The “stratospheric pathway” proposed to link Arctic sea-ice loss to changes in …

Characterization of the spatial and temporal variability in pan-Arctic, terrestrial hydrology
<p>Arctic hydrology represents an important component of the larger global climate system, and there are signs that significant water-cycle changes, involving complex feedbacks, have occurred. This dissertation explores the methods to estimate components of the arctic hydrological cycle, the …

Changes in frequency of extreme temperature and precipitation events in Alaska
… in Alaska. This research examines corresponding changes in frequencies of extremes of temperature and precipitation based on daily data from 26 Alaskan surface weather observing stations from 1950 to 2008. Extreme events were defined as the upper one percentile of events. Data were analyzed …

Polar Bear (Ursus Maritimus) Foraging Ecology in the Western Canadian Arctic
Climate change has led to abrupt declines in sea ice over the past three decades. Polar bears (Ursus maritimus) rely on sea ice as their primary habitat to hunt marine mammal prey. Due to their position at the top of the Arctic marine food web, polar bear foraging patterns can provide insights on …

Identifying impacts of non-climatic factors on food security of Indigenous Peoples in the pan-Arctic region
This thesis explores the vulnerability of Arctic Indigenous food systems to food insecurity resulting from the combined impacts of climatic and non-climatic stressors. While climate change poses significant threats to traditional food practices and access, this study emphasizes the importance of …

Microbial communities and their response to Pleistocene and Holocene climate variabilities in the Russian Arctic
The Arctic is considered as a focal region in the ongoing climate change debate. The currently observed and predicted climate warming is particularly pronounced in the high northern latitudes. Rising temperatures in the Arctic cause progressive deepening and duration of permafrost thawing during …

Arctic Cloud, Radiation and their Interactions with Sea Ice
Over the past few decades, the Arctic has experienced dramatic changes, the most recognized being the amplified warming and substantial decline in both sea ice coverage and thickness at impressive rates. The cloud-radiation feedback is believed to be one of the critical reasons for Arctic sea ice …
