Abstract: A continuous development and increasing urbanization at the coastal zones have occurred with little regard to the consequences of rising sea levels associated to climate change. An improved understanding of climate change and sea level rise should be provided to reduce the uncertainties corresponding with sea level rise projections which contribute to local adaptation planning. This review has provided an overview of 20 years scientific investigation on sea level projections and information of paleoclimate history from the last era. The presence of uncertainties and bias in the previous study related to sea level projections need a lot of improvement in the future. This review ends with a recommendation to conduct a more precise analysis by applying similar guidelines for all analysis among all researchers across the globe as well as full attention on the chosen of assessment approaches, related method and selection of space, time and distributional scale for analysis.
