Earth is Drowning: Global Sea Level Rise Grossly Underestimated

Global sea level rise has been assumed to have been rising at an average rate of 1.5 centimeters (0.6 inches) per decade since 1900, as measured by NOAA. However, a new study has cast that figure into doubt: after having taken regional sea level increases into account, the previously accepted rate may be off by a great deal -- from 5 to 28 percent in some regions.

The problem comes from the fact that sea level measurements have been historically taken from coastal tide gauges, from roughly a dozen select sites around the northern hemisphere. It was assumed in the past that ocean levels were rising relatively evenly across the globe, however:
