2nd Annual Ian Church Memorial Lecture
Applied climate research in northern Canada
Dr. Ronald Layden, Manager, North Slave Research Centre, Aurora College, Yellowknife
Tuesday, May 29, 2018, 7:30 pm Beringia Centre, Whitehorse
How is climate change directly affecting Northern communities today, and what are their research priorities as a result? Join Ronald Layden as he describes several related studies: 1) understanding how climate change is impacting basin hydrology and hydroelectric energy production in the NWT; 2) the challenges of using solid waste gasification systems for energy in Northern communities; 3) improving ice roads and increasing their efficiency and 4) a methane survey in the Mackenzie Delta from the Yukon to the Arctic Ocean.
Effects of dust storms on ancient and modern climates in proglacial valleys

In the Yukon, and in other high latitude mountainous areas, warming temperatures within glaciated valleys are causing increased glacial melt. The eroded sediment thus left exposed frequently becomes wind-blown dust. Such events of the past are evident in layers of loess within the surrounding soils. This mineral-rich dust not only provides essential nutrients for aquatic and terrestrial productivity, but also affects the earth’s radiation balance. The extent of its effect is a major source of uncertainty in global climate change models. Join James King as he explores how these dynamics interoperate, with special reference to the Slims River (A'ay Chu) valley.
