Fox News Flash top headlines for March 2 Almost half of the world’s sandy beaches could be gone by 2100 if climate change continues as is, according to a new study published on Monday.
The research, published in the scientific journal Nature Climate Change, forecasts that coastlines, which are densely populated, could see further erosion. The scientists used satellite imagery to track how beaches have changed over the past 30 years.
“A substantial proportion of the world’s sandy coastline is already eroding, a situation that could be exacerbated by climate change,” researchers wrote in the study’s abstract. “Here, we show that ambient trends in shoreline dynamics, combined with coastal recession driven by sea level rise, could result in the near extinction of almost half of the world’s sandy beaches by the end of the century.”
Speaking with The Associated Press, the study’s lead author, Michalis Vousdoukas, said that half of these beaches “will experience erosion that is more than 100 meters. It’s likely that they will be lost.”
Beaches are valuable for recreation, tourism and wildlife, while also providing a natural barrier that protects coastal communities from waves and storms. A study published in February suggested that extreme weather events caused by climate change could result in an economic recession “the likes of which we’ve never seen before.”
Many coastal areas, including beaches, are already heavily affected by human activity such as seashore construction and inland dams, which reduce the amount of silt flowing into oceans that’s crucial for beach recovery[…]
