You may wish to look at some of the mass balance studies of the ice on Antarctica and Greenland. You will find that there is no consensus that either is loosing ice. The consensus is that increases in global temperatures (up to about 3 deg C.) melt the edges of the glaciers but lead to thickening of the glaciers at higher elevations due to increased precipitation. It does appear that the average global temperature has recently been rising at about 0.2 deg C/decade. How much of this is due to human activity is unknown. It is also unknown whether or not humans can do anything to stop climate change. It may be far more cost effective to develop plans to adapt to climate change rather than try to prevent it.
