Much of the Earth’s ice is melting at an unprecedented rate. If we had no other information than this, we would be forced to conclude that the Earth was warming. The Earth’s ice deposits can be divided into four broad groups: (1) mountain glaciers, (2) sea ice, (3) ice sheets, and (4) ground ice in permafrost. All four types are left over from the end of the last ice age. During the Hot House periods in Earth’s history there were no accumulations of ice.
