New research finds evidence of climate-driven changes to northern lakes

Across the Old Crow Flats in the northern Yukon, lakes are telling a story of climate-driven change. The traditional territory of the Vuntut Gwitchin First Nation (VGFN), the Old Crow Flats is recognized as a Ramsar Wetland of International Importance thanks to its more than 8,000 thermokarst lakes (up to 15 square kilometres) and ponds. Thermokarst lakes are formed by thawed permafrost and can be prone to drainage if they expand into low-lying areas. Kevin Turner, an Associate Professor in Brock’s Department of Geography and Tourism Studies and Fulbright Canada Research Chair in Arctic Studies at the University of Washington, has studied the area since 2007, and he says that warmer temperatures, longer summers and more rain are “priming this important landscape for continued climate-driven landscape change.”
