University Of Idaho Researchers Develop Model To Better Understand Glacier Behavior, Climate Change Implications
March 15th, 2025
University of Idaho researchers have developed a mathematical model that simplifies the way scientists understand changes in glacier movement. This new approach demonstrates that diverse patterns of ice flow — ranging from short-term fluctuations to multiyear trends — can be explained using a single set of fundamental equations.
