GENTHON, G. KRINNER, H. CASTEBRUNET (Annals of Glaciology 50 2009)<br /><br />Here: http://www.igsoc.org:8080/annals/50/50/a50a101.pdf<br /><br />The paper suggests that the INCREASE in snow and ice on the margins of Antarctica may cause the rate of rise in global sea level to be 1 mm per year LESS than the rate of rise otherwise expected..<br /><br />The increase in sea ice can be linked to increase in precipitation on the margins of Antarctica. This is what one would expect intuitively, since the melting of the grounded coastal ice in accompanied by an endothermic process that causes refreezing as sea ice.<br /><br />A buildup of snow on top of the glacier adds weight and causes strain within the ice (shear) and thus increases the amount of ice moving down slope and calving from the seaward margin of the grounded ice. <br /><br />What needs to be explained is the increase in precipitation over the margins of Antarctica. <br /><br />Since the interior of the continent is a desert, snowfall on the plateau can be ignored.Frank Waltershttps://www.blogger.com/profile/17403044995764984391noreply@blogger.com
