     A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding to

the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during

this century and global seas could rise as much as 3 feet.

     The rates of change that we're noticing are much higher than expected. If these rates continue, it is not

likely that Greenland could shrink by several tens of percent this century. However, it's not known how

quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.

     Greenland is the world's largest island, covering area more than three times the size of Texas. Some 81

percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice.

Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier's front is the point

where the water is deep enough that the glacier floats.

     Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving

back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by

more than 130 feet since 2001. And over these past years, its trip to the sea has sped up from about 70

feet per day to nearly 110.

     The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five

degrees Fahrenheit(华氏温度) in the last ten years. Since most of Greenland's ice is on land, seas will rise

as the ice melts. If all Greenland's ice sheet melted, oceans would be 15-20 feet higher. Nobody expects

that to happen any time soon.
