Communities, resource managers, and decision makers in Arctic Alaska are in need of scientific information to base important decisions related to anticipating and adapting to changes in temperature and precipitation. Since its inception in 2011, the Alaska Climate Science Center (AK CSC) and its partners have produced a variety of scientific products and datasets aimed at supporting this need and increasing climate change resilience in the Arctic. However, much of the information related to these activities is dispersed across many technical publications, and is often not readily accessible to those outside the research community. In an effort to make this science more available and accessible, the AK CSC is working...

In Arctic and sub-Arctic regions, snow plays a crucial role in atmospheric and hydrologic systems and has a major influence on the health and function of regional ecosystems. Warming temperatures may have a significant impact on snow and may therefore affect the entire water cycle of the region. A decrease in precipitation in the form of snow, or “snow drought”, can manifest in several ways including changes to total snowfall amounts, snow accumulation, and the timing/length of the snow season. Understanding these changes is then critical for understanding and predicting a variety of climate impacts to wildlife and ecosystems. However, little research has been conducted to date to understand how this change may...

Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/gcb.12757/abstract): The landscape of the Barrow Peninsula in northern Alaska is thought to have formed over centuries to millennia, and is now dominated by ice-wedge polygonal tundra that spans drained thaw-lake basins and interstitial tundra. In nearby tundra regions, studies have identified a rapid increase in thermokarst formation (i.e., pits) over recent decades in response to climate warming, facilitating changes in polygonal tundra geomorphology. We assessed the future impact of 100 years of tundra geomorphic change on peak growing season carbon exchange in response to: (i) landscape succession associated with the thaw-lake cycle; and (ii) low, moderate,...

Alaska’s land, water, plants, wildlife, and seasons are undergoing a great upheaval, and its people, especially the communities living in remote villages are directly and severely impacted by these widespread environmental changes. These changes are not only widespread but also often so rapid that we cannot possibly have enough scientists and professionals on the ground to detect and predict these changes before their effects are obvious. Especially environmental changes occurring in and around the remote communities in Alaska are directly affecting the subsistence resources and practices, thus have the most impact on the socio-economic conditions of these communities. In order to detect, monitor, and forecast these...

Snow is extremely important to a wide range of natural processes in Alaska. Snow cover helps regulate the earth’s temperature and stores water on the landscape. As it melts, snow hydrates the soil and replenishes the freshwater supplies of streams and lakes, providing water for vegetation, wildlife, and human activities such as agriculture and electricity generation. Understanding present and future snow conditions under climate change is critical for managing Alaska’s natural resources, yet many scientists, land managers, and policymakers lack this information at useful scales. Hence, the goal of this project was to produce an advanced snow modeling system for part of the Arctic that predicts a variety of factors...

Permanently frozen ground, known as permafrost, is a critical feature of the Arctic landscape. As temperatures warm, permafrost is thawing, with potentially adverse impacts to infrastructure, communities, and the structure and function of Arctic ecosystems. However, the processes leading to changes in permafrost are not well understood, and there is a need to better understand the vulnerability of permafrost to thaw. Addressing these gaps in information regarding permafrost characteristics and dynamics, and what these changes will mean for human communities and ecosystems, will support management and planning efforts. This project seeks to address these gaps through several mechanisms. First researchers have synthesized...

Permafrost is a layer of perennially frozen soil that primarily exists in and around the Arctic and Antarctic regions of the world. While a shallow near-surface soil layer (called active layer) thaws during the summer and re-freezes in the winter, the underlying permafrost remains perennially frozen, often underlying buildings, roads, and other infrastructure. As warmer temperatures become more common, thawing of permafrost could have major consequences for Alaska. Where thawing has already occurred, dramatic changes in ecosystems and existing infrastructure are evident. For example, thawing permafrost along the ocean shore and riverbanks in Northern Alaska is causing substantial coastal erosion and is impacting...
