College of Charleston professor Dr. Mitchell Cogan then stepped forward to present the science behind the rising tides. There are three main reasons for sea level rise: the subsiding of land, thermal expansion (warming oceanic temperatures), and addition of water to the basin. The third can cause the greatest impact, and is applicable to the earth’s current situation, with an influx of water coming from melting ice in Greenland and Antarctica.
