Glaciers have a powerful impact on the North Cascades of Washington. These natural reservoirs provide 25% of the North Cascade regions total summer supply. Due to climate change, the glaciers will continue to retreat in the foreseeable future.
About Mauri S. Pelto
Dr. Pelto has been a professor of environmental science at Nichols and the director of the North Cascades Glacier Climate Project for 35 years. Pelto's research team has recorded the mass balance of numerous glaciers, all of which are retreating due to global warming, which has raised temperatures; which in turn has increased melting and increased the frequency of winter rain and melt events that reduce winter accumulation on North Cascade glaciers. This has led to the retreat of all 47 glaciers we monitor, with four of those glaciers having disappeared. The reduction in volume and area is reducing summer contributions to streamflow.
