A recent report by the World Meteorological Organization titled “State of Climate in Africa 2023” revealed that major Moroccan coastal cities, including Casablanca, Tangier, and Agadir, are at risk of sea level rise, coastal erosion, and land submersion, especially during severe storms.
In a special statement, the Moroccan General Directorate of Meteorology explained that international institutions frequently warn about the risks of sea level rise and its potential consequences for coastal cities worldwide, particularly in low-lying areas. They added that these warnings are based on data showing continuous increases in sea levels due to climate change, which leads to ice melting and rising temperatures, causing ocean water expansion.
The report indicated that Morocco experiences varying rates of sea level rise between its Atlantic and Mediterranean coasts. While the Atlantic coast records a rise rate of less than 3.4mm annually, close to the global average, the Mediterranean coasts show a lower rate of 2.8mm per year.
The Directorate explained that sea level rise occurs due to polar ice melting and thermal expansion of water caused by climate change, posing a future threat to coastal cities and low-lying areas, especially with accelerating global warming, which may lead to coastal flooding, beach erosion, and groundwater salinization.
In concluding its statement, the Directorate emphasized that addressing these challenges requires global efforts to reduce carbon emissions and enhance preventive measures, along with developing infrastructure capable of withstanding climate changes.
