Combining satellite images with other data, glaciologists from the Laboratory for Studying Geophysics and Space Oceanography estimate the glacier lost an average of nearly 1.5 metres (4.9 feet) in height each year by 2003, shedding almost 22 percent of its original volume. In terms of area, the glacier shrank by 1.9 sq. kms. (0.74 sq. miles) per year from 1963 to 1991.
Thereafter the loss doubled, to 3.8 sq. kms (1.48 sq. miles) per year. By 2003, the glacier covered only 403 sq. kms (155 sq. miles), a retreat of 20 percent compared with 1963….
