课时冲关12 UNIT 3 I.阅读理解 主题：人与自然 体裁：说明 Climate change leads to threat to the world's sandy beaches,and as many as half of them could disappear by 2100,a new study has found.Even by 2050 some coastlines could be hard to make out from what we see today,with 10%to 12% facing serious erosion(侵蚀). Using updated sea level rise predictions,the researchers analyzed how beaches around the world would be in a future with higher seas and more damaging storms.They also considered nat- ural processes like wave erosion,as well as hu- man factors like coastal building develop ments,all of which can affect a beach's health. The study found that sea level rise is expected to outweigh these other factors,and if countries do not cut pollution quickly,rising seas could per- manently destroy beaches and coastal towns in the near future.Additionally,the more green- house gases humans release into the air,the greater the negative impact on beaches worldwide will become. It's hard to overstate just how important the world's beaches are.They cover more than one third of the world's coastlines and protect coastal areas from storms.Beaches are also important economic engines,supporting relaxation,tourism and other activities.And in some areas,the beach is more than a vacation destination.In places like Australia, life near the coast surrounds the beach for much of the year. Some of the world's most popular beaches are already taking actions.Places like Miami Beach are bringing in large amounts of sand by truck to fix coastlines severely damaged by waves.Meanwhile,some areas have built protec- tive walls to try to keep the sand from washing away.But scientists say the financial and environ- mental costs of these projects are huge,while ris- ing seas,more powerful storms as well as a warmer climate may make this a losing battle. However,the researchers did find that hu- mans have some control over what happens to the world's beaches.If the world's governments can continue cutting greenhouse gas pollution,the researchers found that 22%of projected beach losses by 2050 could be prevented,a number that grows to 40%by 2100 if greenhouse gases are limited.
