Polar Voices

Everyone is talking about climate change, but what does it all mean? Listen in as Polar Voices breaks down the science of climate change with people living and working in the polar regions. 

Polar Voices is an educational podcast that explores climate change in the Arctic and the Antarctic. The program uses current research to explain observations made by people living and working near the poles, focusing particularly on Arctic Indigenous peoples. The main goal of Polar Voices is to increase knowledge and awareness of climate change among lifelong listeners from a broad range of socioeconomic and educational backgrounds. For listeners with limited initial knowledge of climate change, the programs present scientific information in simple and concise language. For listeners with moderate or advanced knowledge of climate change, Polar Voices relay true stories from Arctic Indigenous communities experiencing and adapting to change and discuss actions people and communities are taking to mitigate climate change locally.

Policy-makers are connecting with indigenous peoples through the Snowchange Cooperative to develop Arctic climate change policies. Tero Mustonen, founder of the Snowchange Co-op, describes the initiative and how Arctic communities are adapting to change.

Rivers are the highways of interior Alaska, but climate change is making travel treacherous. Alaska Native Elders come together at the Signs of the Land camp to discuss the past and plan for the future.

You could spend your days in a lab analyzing samples…or you could trek across the Arctic, re-taking images from over 100 years ago. Follow the adventures of ecologist Ken Tape as he captures the effects of climate change on film.

Arctic communities in North America are subjected to more fires every year, which have impacted the local wildlife. University of Alberta professor Mike Flannigan describes how rapid warming in the Arctic is causing an increase in fire activity across the Canadian Arctic and Alaska, and ReAC camp facilitator Malinda Chase discusses what communities can do to limit their fire risk.

Frozen soils, or permafrost, can perfectly preserve animals and plants for thousands of years. But some of these ancient soils are also storing huge volumes of greenhouse gases that will be released as permafrost melts due to rising Arctic temperatures. Studying permafrost behavior under different environmental conditions is allowing researchers to better understand the impact of melting permafrost in the future.

Food insecurity is an issue that Arctic communities are facing as a result of climate change. Landscape changes are altering the migration patterns of some Arctic animals, making it difficult to maintain consistent access to country foods. Although food insecurity in an urgent problem in the north, the lower latitudes are also dealing with climate change-induced droughts that are threatening food crops.

Dr. Ted Schuur is currently a professor of ecosystem ecology at Northern Arizona University and oversees the Ecosystem Dynamics Research Lab. While Polar Voices was conducting interviews, the Schuur lab was located at the University of Florida but has since moved to Northern Arizona University as part of the Center for Ecosystem Science and Society. The lab supports many graduate students and postdoctoral fellows. Marguerite Mauritz is a postdoctoral research associate in the lab studying potential changes in the carbon cycle as permafrost thaws. Elizabeth Webb worked out of the lab as a graduate student and studied what happens to permafrost in winter near Healy, Alaska, as there is still some microbial decomposition taking place. John Krapek is a former field tech at the site. Jamie Hollingsworth is the site manager of the Bonanza Creek Long-Term Ecological Research Station outside of Fairbanks, Alaska. He also works with the Boreal Ecology Cooperative Research Unit, a partnership between the University of Alaska Fairbanks and the U.S. Forest Service. He provides logistical support all around Interior Alaska – including Schuur's work out of Healy.

Dr. Craig Gerlach is the Academic Coordinator for Sustainability at the University of Calgary and a professor in the Department of Anthropology and Archaeology. Prior to joining the University of Calgary, Gerlach spent twenty years as a professor at the University of Alaska Fairbanks where he conducted research on food systems in northern aboriginal communities including the sustainability of fisheries and the socioeconomic impact of oil and gas development. His current research focuses on sustainable food, water, and energy systems in remote northern villages and emphasizes meaningful results for stakeholders. As a result, Gerlach is looking at solutions that will reduce rural village dependence on large urban centers including community gardens, greenhouses, alternative energy sources, water infrastructure, housing and shelter, and novel rural community designs.

Dr. Heidi Swanson is an assistant professor and university research chair at the University of Waterloo in Ontario, Canada. She studies the response of aquatic food webs to climate change and the accumulation of mercury in Arctic lakes. Her lab, the Swanson Lab Group, travels to ecosystems as far west as the North Slope in Alaska and as far east as Lake Superior to study fish ecology and track contaminants in lakes. Her team works collaboratively with other academics, government researchers, Aboriginal communities, and industry to conduct meaningful research for multiple stakeholders. 

Upwards and Northwards: Tree Line Advancement in the Alpine, Subarctic and Arctic. 

As the Arctic warms, the limits of where trees can grow are slowly shifting up mountains and further north. Researchers at the Kluane Lake Research Station in Yukon, Canada are trying to determine the range of environmental conditions that control the position of the tree line and ultimately forecast the position of the tree line in the future.

Warm, Thaw, Repeat: How the Degradation of Permafrost will Amplify Climate Change.


Frozen soils (or permafrost) in the Arctic are thawing, destabilizing the ground surface and damaging buildings and roads. Although infrastructure is crumbling, scientists are more concerned with the potential for runaway global warming as preserved plant material in the soils starts to break down into carbon dioxide. Global climate action plans are in place to limit global warming to 2⁰C, but the huge volume of carbon stored in the soils may push us past that target.

Many glaciers in the Kluane Region are fed by a massive reservoir of snow and ice that sits on top of the St. Elias Mountains. Glaciologists are studying how global warming is affecting the physical characteristics and behavior of these glaciers as they retreat further up mountain slopes.

Sea ice is rapidly decreasing due to accelerated warming in the Arctic. Animals, subsistence hunters, and researchers who rely on the frozen surface are adapting to less ice while trying to preserve their livelihoods.

Coastlines everywhere are hit by waves and storms from rising seas that can eat away at the shoreline, but Arctic coasts once frozen in place by permafrost are especially susceptible to coastal erosion as temperatures rise and permafrost thaws. Increased erosion is threatening some coastal communities, forcing long-standing communities to consider relocation as the land underneath them disappears.

Arctic inhabitants are taking research into their own hands. Rather than letting scientists determine what needs to be studied, Inuit communities in Canada are determining what questions they need answered and seeking researchers who can help them.
