Online published on 11 December, 2013. Abstract The study of sea level rise is an interdisciplinary endeavor as it adapts to a warming climate. Sea Level Rise (SLR) in response to the present and future warming of the earth's surface is probably the most contentious issue being debated at present. Although the past two decades have revolutionized our understanding of sea level rise and its causes, major scientific challenges must be met before useful predictions could be made. The rate of SLR has accelerated considerably in relation to the pre-industrial era. Over the twentieth century, global sea level increased at an average rate of about two mm per year, which is substantially larger than the rate of the previous millennia. Nevertheless, accurate prediction of future sea level rise requires continued observations as well as significant advances in modeling of the coupled ice-ocean-land-atmosphere climate. A major effort is needed to sustain data recording from satellite altimeters, time-variable gravity missions and from autonomous ocean observing systems. In addition, an interdisciplinary research effort is required to address major problems, including improvement of the historical records of sea level rise and ocean warming, the separation of other geophysical processes from sea level rise signals, and a more complete understanding of interactions between the ocean and ice sheets throughout the globe.
