Introduction:

Sea levels have been on the rise ever since the start of the industrial revolution, some aspects of this rise are natural and some human induced. Sea level rise (SLR) has many different effects on global systems including, flooding, saltwater intrusion, salinity and density. These changes will ultimately effect around 40% of the world population, which live within about 100 kilometers of a coastline (Union of Concerned Scientist, 2011). These increased effects will put millions of people at risk of displacement. As stated earlier sea levels have been rising (slowly) since the industrial evolution, but in the last few decades (early 1990s) there has been a significant increase (see figure. 1)(Nicholas & Cazenave 2010). A common argument Figure 1 - retrieved from http://www.sciencemag.org/content/328/5985/1517/F1.large.jpg is that the technology for measuring sea level was irrelevant and inaccurate until the beginning of the 1990s. This can be seen as true yet the IPCC has been releasing more accurate findings in their most recent reports. The latest IPCC report predicts that sea levels will rise by 52 - 98cm globally by the year 2100 if nothing is done to slow down fossil fuel emissions (Rahmstorf, Stefan 2011). There are four general scenarios (see figure 2) created by the IPCC to help people get a further understanding, RCP2.6 is the most ideal scenario where humans slow down most fossil fuel consumption while finding a way to combat climate change and…
