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.
