USA Alternate Commissioner

Jon Riedel

Jon Riedel was until recently a geologist with the U.S. National Park Service at North Cascades National Park, and holds a master’s degree from the University of Wisconsin (1987) and a doctorate from Simon Fraser University (2007). For more than 30 years his research focused on the sensitive response of Washington’s glaciers to climate change, from the last ice age 30,000 years ago to modern glaciers. Riedel’s recent research into the distant past has focused on glaciation of the valley and environmental conditions during the last ice age.

Jon currently serves as president and chair of the Skagit Climate Science Consortium, formed in 2009 to integrate the climate change research of 13 scientists from a variety of disciplines to provide information to help decision-makers in the Skagit River watershed understand and adapt to climate change. Jon led the team that, over the course of four years, developed the Stehekin River Corridor Implementation Plan and Environmental Impact Statement (2012). He also developed the North Cascades Glacier Monitoring Program.
