Why didn`t The collapse of the Larsen B ice shelf raise the level of the seas around the world?

Answer 1

it did raise the level, but not enough for you to notice without very accurate measuring machines

Answer 2

Although most of the ice in Antarctica is on land, the Larsen ice shelf is formed over water. If you have a glass of ice water and break one of the ice cubes in two, the level of water in the glass does not rise because the ice is already displacing as much water as it is going to.

Having said that, even if a mass of ice the size of that which broke off from the ice shelf were to break off from the ice on the land and slide into the ocean, sea levels would not rise appreciably because there is not enough mass, even in that large a chunk of ice, to displace very much water across the millions of square miles of the surface of the world's oceans. That much ice crashing into the ocean would certainly create a huge wave, but the effect would be temporary.

Answer 3

there was not enough of a volume of ice to displace that much water. it was a lot of ice, but not compared to the volume of water in the ocean.

Answer 4

it was already floating.
