Australia can suffer the most.
Researchers have warned that climate change and rising sea levels could lead to the fact that by 2100 half of the world’s sandy beaches will disappear.
Even if humanity drastically reduces pollution, by the end of the century more than a third of the sandy coastline will be wiped off the face of the Earth, which will harm coastal tourism in large and small countries.
This is stated in an article in the journal Nature Climate Change, reports Science Alert .
“In addition to tourist spots, sandy beaches often play the role of the first line of defense against coastal storms and floods, and without them, the effects of extreme weather events are likely to be higher,” said lead author Michalis Vusdukas, a researcher at the Joint Research Center of the European Commission.
Some countries, such as the United States, are already planning large defense systems, but in most countries such massive engineering schemes are impossible or inaccessible.
According to the data, Australia could suffer the most, and over the next 80 years almost 15 thousand kilometers of the coastline of the white beach will be washed away. Australia is followed by Canada, Chile and the United States.
Sandy beaches occupy more than a third of the world’s coastline, often in densely populated areas.
To assess how quickly and how much beaches can disappear, Vustukas and his colleagues analyzed satellite imagery data for three decades since 1984.
