Interesting you post that Hanrahan. If you look closely there is definitely a sea level rise occurring. Its difficult to see because a) the chart is over the period 1992 to 2010 (a very short period) and b) the graduations are in meters and c) the sea level rise is measured in millimetres over that period. But it is definitly there. Thanks for posting the chart. People who gave you a thumbs up should probably have a closer look at the chart instead of blindly clicking the button.
