An ice cap is a dome-shaped ice mass that covers less than 50,000 km² of land area (usually covering a highland area). Masses of ice covering more than 50,000 km² are termed an ice sheet. Snowflakes by Wilson Bentley, 1902 Ice is the name given to any one of the 14 known solid phases of water. ... An ice sheet is a mass of glacier ice that covers surrounding terrain and is greater than 50,000 km² (19,305 mile²). The only current ice sheets are Antarctic and Greenland; during the last ice age at Last Glacial Maximum (LGM) the Laurentide ice sheet covered much of Canada...
Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains) but their dome is usually centred around the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Topography, a term in geography, has come to refer to the lay of the land, or the physiogeographic characteristics of land in terms of elevation, slope, and orientation. ... In geology, a massif is a section of a planets crust that is demarcated by faults or flexures. ...

A series of recent studies shows that the polar icecaps, which should be shrinking if dire global warming theories are correct, are maintaining their mass and in fact growing slightly.
The study concluded, "mean ice thickness has remained on a near-constant level around the North Pole from 1986-1997." Moreover, the study noted data from six different submarine cruises under the Arctic sea ice showed little variability and a "slight increasing trend" in the 1990s.
The recent polar ice studies, which measured surface rather than atmospheric temperature trends (and which were far removed from the effects of urban heat islands and questionable third-world temperature readings), lend weight to the argument that satellite readings, not surface monitoring stations, are correct.
