ALASKA'S PUBLIC INFRASTRUCTURE AND ADAPTATION TO CLIMATE CHANGE
Mike Coffey, Statewide Maintenance and Operations Chief, Alaska Department of Transportation and Public Facilities
Alaska’s public transportation system lies within one of the most inhospitable and challenging environments on the entire planet. With approximately 80 percent of the state underlain by ice-rich permafrost, 6640 miles of coastline (more than the other 49 states combined), and roughly 47,300 miles of tidally affected shoreline, Alaska is at the forefront of climate change impacts. In addition, a significant percentage of the state’s transportation system is constructed over permafrost and adjacent to or in close proximity to the coast and other water bodies including rivers, streams, and lakes. For these reasons, Alaska’s transportation system is extremely vulnerable to the impacts of climate change. The Alaska Department of Transportation and Public Facilities (ADOTPF) is responsible for managing the state’s transportation infrastructure in this challenging environment. Mike Coffey will discuss climate change impacts on Alaska’s transportation infrastructure and discuss how the department is adapting to the changing environment. Mike will also discuss the State’s efforts to assist the community of Newtok in their relocation to Mertarvik.

REGIONAL VARIATIONS IN SEA LEVEL CHANGE IN ALASKA
Jeff Freymueller, Geophysical Institute and Department of Geology and Geophysics, University of Alaska Fairbanks
Projections of global average sea level predict significant sea level rise over the next century, due mainly to thermal expansion of the oceans and the melting of glaciers and ice sheets. But the effects of changing sea level in any one place are not determined by the global average, but by the local change in relative sea level -- the level of the sea relative to the level of the land. Transporting water to the ocean from melting glaciers and ice sheets changes Earth's gravity field and causes uplift of the surface due to removal of the ice load. Both of these effects cause regional variations in relative sea level, which can be larger in magnitude than the global average rise. In addition, vertical tectonic motions along large regions of the Alaska coast are more rapid than sea level change. As a result, different parts of the Alaska coast experience both relative sea level rise and fall. In this talk, Dr Freymueller will discuss regional variations in sea level change in Alaska.

METHANE EMISSIONS FROM THERMOKARST LAKES
Katey Walter Anthony, Assistant Professor, Water & Environmental Research Center, University of Alaska Fairbanks
Methane is a potent greenhouse gas released from millions of lakes in the Arctic. The largest methane emissions come from lakes where organic-rich permafrost is thawing. Permafrost organic matter released into the bottoms of lakes fuels methane production, and methane escapes lakes largely by bubbling. Given the huge quantity of organic carbon in permafrost (>1500 Gt C, which is more than twice the atmospheric C content), and projections of permafrost warming and thawing, the fate of carbon and greenhouse gas release is important for understanding climate change feedbacks.

THE SKY IS NOT FALLING, BUT THE OCEAN IS RISING; A skeptic’s view of sea ice loss and marine mammals
Brendan P. Kelly, Research Scientist National Marine Mammal Laboratory, NOAA and Professor, International Arctic Research Center, University of Alaska Fairbanks
Over the past 12 million years, a diversity of mammals evolved specializations for exploiting Arctic sea ice. Other marine mammals—lacking adaptations to ice—have been isolated from one another by sea ice and have evolved along separate paths in the North Atlantic and North Pacific oceans. For the past 10,000 years, Arctic people have developed cultures around the seasonal availability of Arctic marine mammals. Today, 11 ice-associated marine mammal species face unprecedented rapid loss of a continent-sized habitat as Arctic sea ice diminishes. A skeptical analysis (a first principal of science) of ecological and evolutionary data indicate that rapid changes in food resources, predation, competition, and interbreeding threaten many species as well as traditional ways of life among Arctic people. Responding to these changes will require sound analyses, mitigation, and adaptation.

OCEAN ACIDIFICATION: WHAT IT MEANS TO ALASKA
Jeremy Mathis, Professor, School of Fisheries and Ocean Sciences, University of Alaska Fairbanks
Since the Industrial Revolution approximately 1/3 of all human CO2 emissions have been absorbed by the ocean. While this process has mitigated global temperature increases it has had a profound effect on the chemistry of the surface ocean, making the water more acidic. This phenomenon is exacerbated in the cold, highly productive waters in the continental shelf seas surrounding Alaska. Recent observations have shown that the bottom waters over the shelves of the Chukchi and Bering Seas, as well has the Gulf of Alaska become undersaturated with respect to aragonite in late summer and fall. These undersaturated waters could be corrosive to shell building organisms such as clams, oysters, and crabs. Here, the controls and seasonal distribution of ocean acidification around Alaska will be discussed in the context of the import commercial fisheries.

HYDROPOWER PLANNING IN ALASKA: DOES CLIMATE CHANGE MATTER?
Jessie Ellen Cherry, International Arctic Research Center & Institute of Northern Engineering, University of Alaska Fairbanks
The supply, demand, and price for hydroelectric power can be strongly influenced by climatic factors such as temperature, precipitation, and water storage by the environment. The climate, in turn, is driven by both natural variability (on a variety of timescales) and anthropogenic forcing. For planning water resource management here in Alaska, particularly for long-lived, large infrastructure projects, it is useful to understand the sources of uncertainty in climate projections and how they influence long-term and short-term decision-making. A case study in Southeast Alaska is described, where most of Alaska’s hydropower facilities are concentrated. Challenges to assessing the regional impacts of climate change here are discussed, as well as our interpretation of the historical record of climate variability. Our analysis concludes that understanding and accounting for natural modes of variability may be as important as planning for long-term climate change when it comes to managing existing hydropower facilities and planning new infrastructure.

DECISION-MAKING FOR AT-RISK COMMUNITIES IN A CHANGING CLIMATE
Dan White, Alaska Center for Climate Assessment and Policy
Many communities in Alaska are faced with multiple threats to infrastructure and quality of life due, in part, to projected changes in precipitation, temperature, and related incidences of flooding and erosion. Decision-makers must determine how best to manage their community's vulnerability with the knowledge that future environmental change is uncertain. This webinar will discuss a newly released report "Decision-making for at-risk communities in a changing climate" prepared by the Alaska Center for Climate Assessment and Policy. The report is intended to inform decision-makers relating to climate change and uncertainty, risk management, and relocation planning. Issues addressed regarding the planning process for relocation focus on the steps from planning through execution, perspectives on community engagement, partial relocation, site development costs, and timing. Sustainability recommendations focus on defining sustainability, future energy planning, planning for a changing cost of living, and available transportation corridors. Join this webinar to learn more about decision-making for at-risk communities in a changing climate.

CONNECTING ALASKA LANDSCAPES INTO THE FUTURE
Nancy Fresco, Scenarios Network for Alaska Planning, and Karen Murphy, US Fish and Wildlife Service
Understanding how climate change will affect biodiversity and traditional subsistence is a common challenge faced by Federal, State, Native, and private land managers. The Connecting Alaska Landscapes into the Future project (Connectivity Project) was a consensus-based effort that included the U.S. Fish and Wildlife Service and University of Alaska researchers as well as state and federal agency and non-profit partners. The project’s goal was to develop the methodology and thought processes to identify a network of lands that support ecosystem functions to ensure landscape-level connectivity within Alaska given climate change using data that are available today.
In order to model projected changes in statewide biomes and in potential habitat for key species, we gathered data on existing conditions and linked these to models of future conditions, using climate projection data from SNAP, input from project participants, and complex statistical models. With feedback from participants, we refined these models and used them as basis for creating maps of potential future statewide connectivity.
The proof-of-concept results presented in this report are preliminary and are not intended to be proscriptive, but rather to serve as a guide for planning and as a jumping-off point for synergy and further research.

CHANGES TO PERMAFROST IN ALASKA: OBSERVATIONS AND MODELING
Vladimir Romanovsky, University of Alaska Fairbanks
Observed and predicted climatic changes will inevitably change the energy and mass fluxes at the land surface and, as a result, the near-surface and subsurface physical conditions in the Alaskan Arctic and Sub-Arctic. This will trigger changes in ecosystems and infrastructure because the stability of these systems in the north relies on the stability of ice that, so far, holds these systems together. If recent warming trends in the Arctic continue, it will take several centuries to millennia for permafrost to disappear completely in the areas where it is now actively warming and thawing. In losing permafrost, we are losing the stability of these systems. Negative consequences of this degradation will be pronounced from the very beginning because the highest ice content in permafrost is usually found in the upper few tens of meters. In this presentation we will discuss possible effects of degrading permafrost in the Alaskan Arctic and Sub-Arctic on hydrology, ecosystems, infrastructure, and the carbon cycle.

CLIMATE CHANGE IN THE OCEAN: ACIDIFICATION BY ATMOSPHERIC CARBON DIOXIDE
Dr. Jeff Short, Auke Bay Laboratory,
National Marine Fisheries Service
The surface layer of the world's oceans have been acidified by 30% in the last 60 years due to increased atmospheric carbon dioxide levels. Continued unconstrained CO2 emissions may triple ocean acidity by 2100. Such a fundamental and abrupt geochemical shift has significant impacts on marine life, including possible mass extinctions. Cool temperatures and upwelling make Alaskan coastal waters among the most vulnerable to acidification effects, which already threaten shellfish and corals. Many additional, more subtle effects are likely but difficult to predict. Join us for this webinar to learn more about the implications of ocean acidification for Alaska.

UNCERTAINTY IN THE ARCTIC WATER CYCLE
Jessie Cherry , University of Alaska
There are large uncertainties regarding not only the future of the hydrologic cycle and water resources but also their spatial and temporal variability in the present. Many components of the water cycle are difficult to measure accurately, creating one source of uncertainty. Sparse observing networks in the Arctic create another type of uncertainty in that sampling may not be spatially representative. Water-related resource managers must take these uncertainties into account while facing other unknown factors such as the timing of supply and demand and the reliability of infrastructure. This talk will discuss techniques for identifying and where possible quantifying various types of uncertainty.

LAST ICE: THE FATE OF BERING SEA MAMMALS IN RESPONSE TO CLIMATE CHANGE
Gary Hufford, National Weather Service
Sea ice in the Bering Sea is beginning to recede apparently in response to climate change. Walrus and Ribbon Seals seek ice floes as habitat where they breed, give birth and haulout to rest. This makes the walrus and ribbon seal vulnerable to and an indicator of climate change. There is also evidence that the walrus may play a role in the productivity of the Bering Sea by releasing nutrients trapped in pore waters of the bottom sediment when they feed. Join us for this webinar to learn more and and discuss the potential implications of loss of these species.
