Rising sea levels, driven by global warming from fossil fuel emissions, result from the thermal expansion of ocean water and the accelerated melting of land-based ice in polar regions. This phenomenon poses significant threats to coastal communities, leading to increased flooding, storm surges, ecosystem damage, and potential displacement of populations.
Sea level rise is an increase in the level of the world’s oceans due to the effects of global warming. Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere. The oceans then absorb the majority of this heat. As water becomes warmer, it expands. This results in ocean levels rising worldwide.
Land-based ice, such as glaciers and ice sheets, is greatly affected by global warming, as well. These reserves of ice are located in places like Greenland and Antarctica. Typically, they experience melt during the warmer months of the year and the ice is replenished in colder months. With the average year-round global temperatures rising, however, ice caps and glaciers are experiencing a disproportionate amount of melting at an accelerated rate.
Sea level rise poses a serious threat to coastal life around the world. Consequences include increased intensity of storm surges, flooding, and damage to coastal areas. In many cases, this is where large population centers are located, in addition to fragile wildlife habitats. Therefore, people may become displaced and will need to seek safer homes. Even life farther inland is threatened because rising seas can contaminate soil and groundwater with salt. Predicting how high the sea levels will rise is difficult. However, it is an issue that must be carefully monitored so coastal areas can be prepared for the consequences.
