Almost half of the world’s sandy beaches may disappear by 2100, if climate change continues, according to a new study published on Monday.
The study, published in the scientific journal Nature Climate Change, the prediction of the coastline, which is densely populated, you can see further erosion. The scientists used satellite imagery to track the beach has changed over the past 30 years.
“A very large proportion of the world’s sandy coastlines have been eroded, this situation may be exacerbated by climate change,”the researchers wrote in the study abstract. “Here, we show that environmental trends in Shoreline dynamics, combined with the coastal drive of the economic recession due to sea level rise, may result in the extinction of almost half of the world sand the end of the century.”
Some places, will impact significantly less than other people. The authors of the study estimate, the Gambia and Guinea-Bissau in West Africa may lose more than 60% of the beach.
Australia is probably the worst hit in terms of total lost Beach coastline, in more than 7,500 miles. The United States, Canada, Mexico, China, Iran, Argentina and Chile are also at risk losing thousands of miles of coastline, the study added.

Multiple scenarios are considered by Vousdoukas and other researchers, including one where there was a 2. 4 degrees Celsius that global temperatures increase and another a rise of twice the amount.
A separate study, published in the February proposal, if the global temperature rise 0. 5 degrees Celsius in the next 50 years about half the world’s species will become locally extinct. If the temperature rise 2. 9 degrees Celsius, 95 per cent of species will become locally extinct.
The flag of the Paris Climate Agreement, which is agreed in 2015 in the Obama administration, is not taken into account, Vousdoukas told the AP, because it is considered impossible to achieve. In early November, ACE the government began its formal withdraw from the agreement.
As the Paris climate agreement, in which nearly 200 countries signed, including China, the long-term goal is to limit the increase to 1. 5 degrees Celsius.
