A new study says up to one half of the world's sandy beaches could disappear by 2100 because<br />of climate change.<br />Australia, Canada, Chile, Mexico, China and the United States would be among the hardest<br />to hit, the research shows.<br />The study was published in the journal Nature Climate Change.<br />Naturalist Vodacus was the lead investigator.<br />Touristic areas which have sandy beaches at their main sailing point would probably face<br />strong consequences.<br />He said,<br />Aside from economic value, beaches play an important environmental role.<br />Sandy beaches are important habitats supporting a wide range of species.<br />They also protect the coast from the effects of storms.<br />So without sandy beaches, other inland environments can be affected by the effects of waves and<br />saltwater intrusion.<br />Vodacus added,<br />Global sea levels have increased in recent decades.<br />Major courses include melting ice and water expanse as it warms.<br />Researchers examined satellite images showing shoreline changes during the past 30 years.<br />They then used these trends in two different climate change situations.<br />One situation predicted a small reduction in greenhouse gas emissions.<br />The other situation predicted high greenhouse gas emissions.<br />Greenhouse gas emissions have a link to climate change.<br />By 2050, the researchers projected beach losses of between 13 and 15%.<br />By 2100, the projected losses are from 35 to 49.5%.<br />Australia would lose more sandy shoreline than any other country, with 14,849 km projected<br />to be gone by 2100.<br />Canada is second in projected losses.<br />The United States could lose up to 5,530 km.<br />A new study says up to one half of the world's sandy beaches could disappear by 2100 because<br />of climate change.<br />Australia, Canada, Chile, Mexico, China and the United States would be among the hardest<br />hit the research shows.<br />The study was published in the journal Nature Climate Change.<br />Majorless Voodikas was the lead investigator.<br />Touristic areas which have sandy beaches as their main selling point will probably face<br />strong consequences, he said.<br />Aside from economic value, beaches play an important environmental role.<br />Sandy beaches are important habitats supporting a wide range of species.<br />They also protect the coast from the effects of storms.<br />So without sandy beaches, other inland environments can be affected by the effects of waves and<br />salt water intrusion, Voodikas added.<br />Global sea levels have increased in recent decades.<br />Major causes include melting ice and water expanse as it warms.<br />Researchers examined satellite images showing shoreline changes during the past 30 years.<br />They then used these trends in two different climate change situations.<br />One situation predicted a small reduction in greenhouse gas emissions.<br />The other situation predicted high greenhouse gas emissions.<br />Greenhouse gas emissions have a link to climate change.<br />By 2050, the researchers projected beach losses of between 13 and 15%.<br />By 2100, the projected losses are from 35 to 49.5%.<br />Australia would lose more sandy shoreline than any other country, with 14,849 km projected<br />to be gone by 2100.<br />Canada is second in projected losses.<br />The United States could lose up to 5,530 km.<br />Why are sandy beaches important to the environment?<br />Which country will suffer the most according to the research?<br />What is the passage mainly about?
