Trying to be objective I took one of your links and followed it:
Here's what you wrote:
"Another new island in Tonga. It had to have displaced water.

Your statement is: "It had to have displaced water."
For those who haven't check the link ... here is its essence:
"In August 2006, travelers yachting through the Tonga Islands discovered pumice floating on the ocean surface. The pumice resulted from an underwater eruption of the marine volcano Home Reef. Although the pumice eventually floated away, the new volcanic island could still be seen by satellites in the fall of 2006."
If your point is that one small island in the middle of the Pacific, after millions of years, finally broke the surface I agree ... some water was displaced. Relative to the size of the Pacific Ocean ... about a teaspoon's worth.
The relevance to the melting of mountain glaciers, the topic of this thread, escapes me. So you are on your own.
