Dear MEL Topic Readers,
Global sea levels are rising faster and faster. It spells catastrophe for coastal towns and cities
We know why and how much sea levels are rising, yet we aren’t certain how fast sea levels will be rising in the future. Sea levels are rising because of global warming caused by human activities, particularly by burning fossil fuels. Oceans expand as water heats up, and as a result, sea levels rise. Also, sea levels rise as ice sheets melt in Greenland and Antarctica. It is unclear how fast the ice sheets melt as the temperatures increase, whether they’ll melt gradually or rapidly collapse. In fact, the rate of sea level rise has doubled in the last three decades, by about 10 centimeters. Some areas experience higher sea level rise because of regional currents, erosion, tectonic plate movements, and groundwater extraction, like Louisiana in the US. Also, low-lying Pacific islands, such as Tuvalu, Kiribati, and Fiji, are directly affected by sea level rise, and some communities have been forced to relocate. Global sea level rise is a clear and present danger, and it is accelerating.
Read the article and learn again how fast sea levels are and will be rising.
