the problem is the amount of time required for the melt.
tempature is the average molecular motion or energy of a group of atoms. the larger the difference in the air and the ice, the faster it disappears. if the air tempature is not very high, it will not give my energy to the ice, therefore not melting off a large amount. on the other hand there are other ways to melt ice. salt does a good job, as does many pollutants. these things lower the tempature that ice requires to melt. If the glacers are being covered by the pollution that china pumps into their atmosphere, who are they to complain about other ppl raising the global tempature.
oh, just so you know, this fact about the lower tempature needed to melt ice was proven in an elementary science project. so this is also known by school children.
