Rising ocean levels are affected by many things - tectonic plates, gravitational changes, and other things. We have better data now, from things like the GRACE satellites. https://sealevel.nasa.gov/news/76/grace-mission-15-years-of-watching-water-on-earth The GRACE satellites also tell us a lot about ice sheets: https://grace.jpl.nasa.gov/ http://www.nature.com/nature/journal/v491/n7425/full/nature11621.html Antarctica and the YUUUUUGE mass of ice sitting there are changing the shape of the earth, and if all the Antarctic ice melts - it will make Mt Chimborazo (in Ecuador) TALLER than Mt Everest: http://www.npr.org/templates/story/story.php?storyId=9428163 Science is amazing, and very often mind blowing!
