Webinar 1: Mitigation Activities

Synopsis

The Arctic black carbon mitigation initiative grew out of a series of workshops in 2007-8 that were organized by two NGOs, the Clean Air Task Force and the Climate Policy Center, and eventually the international Arctic Monitoring and Assessment Program (AMAP). In 2009 the U.S. Department of State committed $5M toward international cooperation aimed at reducing black carbon emissions in and around the Arctic http://cop15.state.gov/pressroom/133771.html. On the U.S. side, this effort is currently being carried by EPA, DOE and USDA, with a focus on developing emission inventories, mitigation strategies and policies for minimizing black carbon fossil fuel and biomass burning impacts. The U.S. emphasis is on partnerships with the Russian Federation . U.S. mitigation efforts are motivated by concern that the amount of absorbing aerosol deposited on high-latitude snow and ice surfaces is significant, and has measurable impacts on Arctic climate. Russian Federation concerns with black carbon are more centered on human health issues. The mitigation efforts have 3 focus areas : transportation, residential/industrial pollution and biomass burning.

Webinar 2: Arctic Black Carbon Science Activities

Synopsis

Black carbon is "the second most important human emission in terms of its climate-forcing in the present-day atmosphere; only carbon dioxide is estimated to have a greater forcing." When BC is deposited on snow and ice, it darkens an otherwise bright surface. The darker surface may enhance the absorption of solar radiation resulting in an acceleration of snow and ice melting. In addition, BC particles suspended in the atmosphere absorb solar radiation and heat the surrounding air. Atmospheric BC can also alter cloud properties leading to changes in cloud amount and precipitation. Black carbon has multiple sources including domestic combustion for heating and cooking, diesel combustion related to transportation, fossil fuel and biofuel combustion for power generation, agricultural burning, and wildfires. Identification of the sources and types of black carbon (both the geographical region of the source and the combustion process) is necessary for effectively mitigating its climate impacts. In addition, measurements of black carbon are required to verify whether implemented mitigation strategies that target BC emissions from certain sources are actually leading to reductions in BC concentrations in the Arctic atmosphere and surface. In 2013, NOAA's Arctic Report Card added a black carbon assessment to the Atmosphere Section; the primary conclusions of the assessment are that (1) the average equivalent black carbon concentrations in 2012 at locations Alert (Nunavut, Canada), Barrow (Alaska, USA) and Ny-Alesund (Svalbard, Norway) were similar to average EBC concentrations during the last decade and (2) equivalent black carbon has declined by as much as 55% during the 23 year record at Alert and Barrow (Sharma et al. 2013).

Several issues are currently challenging the Arctic black carbon research community:

  • In-situ measurements are the most reliable measure of black carbon; however, the most prevalent techniques which involve filter samplers only make proxy black carbon measurements.
  • Retrievals of aerosols optical depth (AOD) over snow and ice-covered surfaces with passive remote sensing from vis-NIR imagers from space are problematic. Some success over incomplete snow-covered surfaces has been achieved, e.g., with MISR. TOMS, OMI, and probably now OMPS UV passive imaging has some qualitative sensitivity (the Aerosol Index), though with limited sensitivity to near-surface aerosol, and CALIPSO lidar is by far the most sensitive, but with limited coverage.
  • Standardized ground-based networks such as AeroNET, MPLNet, and BSRN have sparse and sporadic Arctic coverage, and are uncoordinated with the necessary black carbon-in-snow measurements, and some long-standing surface stations have actually been decommissioned in the past few years.
  • A promising approach to assessing high-latitude aerosol effects is to constrain aerosol transport models with satellite observations taken at lower latitudes, near the aerosol sources (mainly Boreal fires and pollution sites) where and when the surface is not snow-covered.

Synopsis

Characterized by vast amounts of carbon stored in permafrost and a rapidly evolving landscape, the Arctic has emerged as a focal point for the study of climate change. The Next-Generation Ecosystem Experiments (NGEE Arctic) project, sponsored by the Department of Energy (DOE), Office of Science, is planned as a 10-year effort to deliver a process-rich model of terrestrial ecosystems in which the evolution of Arctic landscapes in a changing climate can be modeled at the scale of a high resolution Earth System Model grid cell. Initial research is focused on the North Slope of Alaska where thaw lakes, drained thaw lake basins, and polygonal tundra offer distinct land units for field and laboratory investigation, and multi-scale modeling. This project was launched from an understanding of decades of ecosystem and climate change studies conducted by federal and state agencies in Alaska and throughout the pan-Arctic. NGEE Arctic scientists will present a series of talks that highlight critical aspects of the project and how a close coupling between process studies and modeling can inform and advance research in this area. Opportunities to collaborate through investments by other state and federal agencies will be discussed.

Synopsis

Stephen Tanner, Project Manager at the National Snow & Ice Data Center, will present an in-depth overview of the Satellite Observations of Arctic Change (SOAC) website (http://nsidc.org/soac/). The SOAC site exposes NASA satellite data and research on Arctic change, in the form of maps that illustrate the changes taking place in the Arctic over time. Change maps of seven selected datasets available on this website include: near-surface air temperature, water vapor, sea ice, snow cover, vegetation, frozen ground, and annual minimum exposed snow and ice. Steve's presentation will entail a demonstration of the site features, including how users can view the data and how the data shows change over time. He also will explain how the data was processed and where to get more information. The presentation will conclude with a general discussion focused on questions and feedback on the site.

Synopsis

Understanding the challenges to food security in the rapidly changing Arctic and ensuring safe and consistent availability, access, and usage of food resources for indigenous communities is critical for sustaining livelihoods, promoting health and well-being, and helping to preserve cultures, traditional knowledge, and socio-linguistic heritage. Given projected climatic and environmental changes, with expected concomitant development activities and opportunities for increased natural resource exploitation, reliance on community-based monitoring programs to track changes in the distribution and relative abundance of food resources, along with impacts on biodiversity, cultural identity, health, language, livelihoods, and traditional knowledge, will be crucial for safeguarding sustainable communities in the Arctic.

Speakers

Building a Conceptual Framework on How to Assess Food Security From an Alaska Inuit Perspective

Carolina Behe (Traditional Knowledge / Science Advisor, Inuit Circumpolar Council - Alaska)

Abstract

The Inuit have called the Alaska Arctic home for at least the last 10,000 years. Their daily lives, culture, language, food, and overall survival have been shaped by the world around them and, in turn, are an intricate part of that environment. Recent years have seen an increased effort in biodiversity monitoring, climatological and oceanographic data collection from the many stakeholders taking interest in the Arctic. Yet, little is linking this research together or to the human dimension. Meeting the formidable challenges brought on by climate change, a changing environment, and increased industry requires an enhanced understanding of the human dimension and its role in the food web. In this presentation, the Inuit Circumpolar Council-Alaska will provide a description of their project, "Building a Conceptual Framework on How to Assess Food Security From an Alaska Inuit Perspective," and provide a basic review of how food security is generally defined throughout the world and preliminary findings of an Inuit understanding of food (in)security and its drivers. The presentation will also highlight the methodology employed to conduct this project and the importance of utilizing Traditional Knowledge approaches in evaluating and validating the information collected.

Social Science Contributions to Understandings of Food Security in the Bering Strait Region of Alaska

Julie Raymond-Yakoubian (Social Science Program Director, Kawerak, Inc.)

Abstract

This presentation will provide an overview of several of the ongoing and new challenges to food security being experienced by indigenous Bering Strait residents, as well as related research, advocacy and other work being conducted by Kawerak, Inc., the regional non-profit corporation providing services to the Bering Straits communities. The presenter will highlight two ongoing Social Science Program projects: the Community-Based Documentation of Ice Seals and Walrus project involving collaborations between Kawerak, nine tribes, two marine mammal organizations, and a conservation organization; and the Indigenous Knowledge and Use of Ocean Currents project, a collaboration among Kawerak, three tribes, researchers, and communities in Chukotka. The presentation will focus on the methods used to document project data, to develop ongoing community relationships, and the connections between these research projects and food security issues in the Bering Strait region. Also highlighted will be several of the changes that Bering Strait communities have observed and are concerned with, as well as the importance of the connection between human well-being and the health of the marine environment.
