In the reference article, it states:

"...the melting of the Greenland ice sheet, which will raise global sea levels significantly..."



 On a simplistic level, when a chuck of ice that is floating in a glass of water melts, the water level does not rise; so, why would the melting of the Greenland ice sheet cause sea levels to rise significantly everywhere. I can think of several scenarios where the above would be true--for example, the earth's surface has changed such that the gravitational potential that initially held the water in Greenland would no longer hold the water--but they would be just made up stories.  Does anyone know the reason why professor Lovelock 's statement is true?

=================



Because almost of all of the ice in the Greenland ice cap is not floating, it is grounded on the rock of Greenland.  That is also true of a smaller, but still large fraction of the ice in the Antarctic ice cap.
