Yiwu, I couldn't fathom your post. Here's my understanding: 1) The ice shelves are floating, so if the ice in the shelves melts it does not directly cause a rise in sea levels (as correctly pointed out by Elmat). 2) However, the ice shelves act like a "cork" that plugs the land glaciers and slows their discharge into the sea. If the ice shelves disappear, then the land glaciers speed up and discharge bergs into the sea faster. This causes a rise in sea level, regardless of whether or not the ice melts. 3) If all the land ice in Antarctica melts (or simply slides into the sea), sea levels will rise 200 feet. The Greenland ice cap adds another 20 feet or so if it goes. -Snow
