Icy relief

Ice sheets in western Greenland have become thicker by about two m in the last 10 years. Kenneth jezek and his colleagues from the Ohio State University, contend that each year adds about 15 cm. They feel that continued monitering of the ice sheet would provide insight into the phenomenon of global warming (New Scientist, Vol 148, No 2003).

What is interesting is that the thickening of the ice sheet in Greenland is slowing down the rise of the sea by 10 per cent, whereas elsewhere in the world sea levels are rising at the rate of 20 mm per decade.
