Dr. Pelto has been a professor of environmental science at Nichols and the director of the North Cascades Glacier Climate Project for more than 20 years.

In teaching, Dr. Pelto’s goal is for students to obtain an understanding of environmental geologic topics, how they affect the world and our lives, and ways to better manage the environment. As part of his classes, he takes students on numerous field trips to complete consulting work on local rivers.

He and his research team have recorded the mass balance of numerous glaciers, all of which are retreating due to global warming. This has led to the disappearance of several glaciers and the development of the first model for forecasting glacier survival.

He has written several articles on glaciers including: “Vanishing Glaciers,” and “Change in longitudinal profile on three North Cascades glaciers during the last 100 years.”

He currently teaches the following courses:

  • World Economic Geography (co-teach)
  • Physical World
  • Digital Applications
