Glaciers out of balance

Scientist studied about 144 glaciers in the world which are likely to lose about 40% of their volume. It was suggested that the glaciers will commit about 30% of their area and about 38% of their volume to global sea level rise.This will happen in the next decades to centuries

A glacier is in balance when the snow at higher, colder elevations equals the volume of snow and ice lost through melting at lower, warmer elevations.If precipitation is greater, the glacier will increase its mass; if melting dominates, the glacier will thin and retreat.

Assessment indicated that climate conditions have changed so fast that many ice bodies have not had time yet to fully adjust.This means a certain amount of mass loss is already locked into the system even if there is no further warming.
