It is the melting of the ice on above the water surface minus the difference in volume of the ice below the surface and the water it would become. Someone else mentioned that if the entire iceberg were melted it would cover California with 4.5in of water. If you divide that by the ratio of the ocean area to the area of California you get 0.13mm. I'm not sure how much is above the water vs below the surface but it seems like a reasonable thing for them to estimate.
- idlewords 9y agoJust enough of it is above the surface to account for the change of volume when it melts. Or equivalently, it displaces its own weight in water.
- spullara 9y agoHmm. I see what you are saying. So they probably did do the calculation I referenced but I agree it is probably faulty. However, there is some rise from melting: https://www.newscientist.com/article/dn18841-melting-icebergs-boost-sea-level-rise/ https://www.newscientist.com/article/dn18841-melting-iceberg...
