The following pie diagrams show the distribution on Antarctica, Greenland, and other glaciers of ice volume, their present contribution to sea level rise, and the precipitation on the glaciers.
This is the present situation, but if all ice on Antarctica melted the sea level would rise 61 m, while melting of all other glaciers and ice fields in the world would only rise the sea level 0.5 m. It is therefore surprising to see that seventy per cent of the present melting glacier induced sea level rise is due to the small glaciers. Today the sea level rises about 3 mm per year. Half of this is due to melting of glaciers, and the other half due to thermal expansion of the sea water.
The figures are based on a Svalbard Science Forum news article and a research article (in Norwegian) from the University of Oslo.
