Even though these glaciers contain only 1 percent of the water tied up in the great ice sheets of Antarctica and Greenland, they could account for 60 percent of an anticipated rise in the world's sea level by the year 2100.

Sea-level rise is seen a key consequence of global warming, and much of the concern has focused on the big ice sheets that contain the vast majority of the world's ice.

Researchers writing in the online journal Science Express estimate melting glaciers, which are located all over the globe including in the tropics, could add between 4 and 10 inches (0.1 to 0.25 metres) to world sea level this century.
