About Mauri S. Pelto-Science Director
Dr. Pelto has been a professor of environmental science at Nichols College and the director of the North Cascades Glacier Climate Project for 39 years. Pelto's science 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.
