Question

The figure below shows the average change in glacier mass per unit area for various mountainous regions around the world. Why are the globe’s mountain glaciers shrinking? Does glacial melt increase or decrease the amount of water stored on the continents? What are the factors in the continental water budget equation that must change in order to restore equilibrium when glaciers melt ? What is the effect on global sea level?
