Interesting notion, I'd never come across that before. I've seen many demos of what the Earth could look like with all the ice melted but I'm not sure any of them took what you're describing into account.

" The mass of ice on the earth's poles has also led to the shape of the planet via tectonics over thousands of millennia. As that mass melts and redistributes from a solid to a liquid spreading around the globe our spheroid will begin to rebound. We have sensors everywhere, even in space, so the resulting effects will not be a surprise to some when the 'mass'ive shift begins. As those tectonic events increase in frequency so too will volcanic activity so I ask if anyone else has been checking on such data? "
