       Glaciers are usually associated with colder climates. But some mountain ranges of South America,Africa, and Indonesia are also   26   glaciers and ice sheets. These tropical glaciers serve as a majorsource of water supply to one-sixth of the world’s population.
       A newly published study, however, revealed that rising temperatures are posing an   27     threat tothe last tropical glaciers in Indonesia’s Papua region. The ice sheets, which once spanned 20 squarekilometers, are thinning over five times as quickly compared to a few years ago.   28     already shrunkby 85% to a mere 0.5 square kilometers, Papua’s glaciers will completely disappear within a decade,researchers have predicted.
       The disappearance of the glaciers will also leave a significant   29     impact. For many indigenousPapuans, the ice sheets represent a sacred symbol. “The mountains and valleys are the arms and legs oftheir god and the glaciers are the head,” explained the head researcher.
       The study warned that Papua’s glaciers are only the “first to go” if greenhouse gases are   30         andtemperatures continue rising. And this is certainly a serious warning about the depressing fate of otherglaciers around the world.
