Mean Sea Level: The Effect of the Rise in the Environment

Abstract

Mean sea level is a significant phenomenon in geodetic science and oceanography. The sea level has experienced an unprecedented rise recently, and this increase can be attributed to the various human-induced activities (anthropogenic factors) ranging from deforestation to burning of fossil fuels and population increase. Several factors cause sea level rise, it has been identified that the thermal expansion of ocean water and the melting of glaciers add to the volume of water causing global sea level to rise, whereas phenomena such as ocean current, wind, pressure are responsible for the regional sea-level rise. This paper identifies climate change and global warming as the drivers of some factors causing the sea level to rise. The effect of sea-level rise has resulted in a loss of agricultural lands, destruction of transportation infrastructures, loss of lands in coastal zones and migration, and the death of some aquatic animals due to saltwater intrusion. In this paper, we reviewed several literatures published between 2017 and 2021 on -level rise and the cascading impacts of sea-level rise in various world areas. The papers reviewed borders on the mean sea level rise from different geographical areas on Earth and the monitoring of sea-level rise using different techniques. Some recommendations were also proposed for consideration.

Assessment and Prediction of Sea Level and Coastal Wetland Changes in Small Islands Using Remote Sensing and Artificial Intelligence

“…In response to these needs, this study employs new datadriven hybrid AI model(s) to provide predictions of the sea level in the FSM and the Globally, sea level rise (SLR) is caused by a combination of the thermal expansion of ocean waters and freshwater input from melting glaciers and ice sheets, increasing the total volume of water in the sea [4]. At a regional level, ocean currents, wind and pressure changes can contribute to SLR [5]. While international climate negotiations often focus on air temperature thresholds [6], even a 1.5 • C target is predicted to result in significant SLR.…”

Feasibility of Photovoltaic-Powered Hydrogen Production for Off-Site Refueling Stations in Iraqi Cities: A Techno-Economic Analysis

“…Climate change is a formidable threat that manifests through escalating global temperatures, melting glaciers, rising sea levels, and an uptick in extreme weather occurrences. These environmental changes have profound implications, impacting human health, agriculture, and economic stability [1]. In 2021, Iraq CO2 emissions from its electricity production, industrial, transportation, and building sectors totalled 153.18 million tonnes.…”
