New Model Predicts How Debris-Covered Glaciers Will React to Climate Change

by Lindsay McCord

Glaciers are vulnerable to melting due to climate change, however debris-covered glaciers respond differently to changes in temperature due to insulation from the debris. A new model factors in this variable for debris-covered glaciers in order to predict how these glaciers will react to a changing climate. Focusing on the Khumbu Glacier in the Himalayas of Nepal, the model predicts a loss of 8-10% of total glacial mass by 2100 followed by increased losses as the tongue (frontmost part of the glacier where debris accumulates) separates from the rest of the glacier. This separation process exposes more surface area of the glacier which causes accelerated loss of mass. Continue reading
