Bye-bye beaches?
Beaches in the United States will be"greatly affected.Half of the world's beaches could disappear by 2100 because of severe erosion linked to climate change, aThe main causes are sea-level rise and erosion from storms, the study says, which warned of"the near-extinction of almost half of the world's sandy beaches by the end of the century."
The study found that West Africa will see some of the worst losses, where more than 60% of sandy coastline may be lost in countries such as The Gambia and Guinea-Bissau. Beaches are valuable for recreation, tourism and wildlife while also providing a natural barrier that protects coastal communities from waves and storms.“The projected shoreline changes will substantially impact the shape of the world’s coastline,” more than a third of which is sandy beach, the authors write.
"Sea level has been increasing at an accelerated rate during the past 25 years and will continue to do so with climate change," the study says."There is a clear cause-and-effect relationship between increasing sea levels and shoreline retreat, pointing to increased coastal erosion issues."
