Global warming will cause of half of the world’s beaches to disappear

……….Climate change and sea level rise are currently on track to wipe out half the world’s sandy beaches by 2100, the journal Nature Climate Change published a study entitled “Sandy coastlines under threat of erosion,” which discusses the impact of global warming on sea-level rise that could result in more than half of the world’s beaches by 2100. Although humanity has made efforts to reduce the use of fossil fuels that cause global warming. The country that will be most affected is Australia due to its beaches, nearly 15,000 kilometers long, which in 80 years the beaches of countries such as Canada, Chile, the United States, Mexico, China, Russia, Argentina, India and Brazil will disappear, in addition to being massively populated areas, are also an important coastal tourism.

……….A less dire scenario, RCP 4.5, would see humanity cap global warming at about three degrees Celsius. Under RCP8.5, the world will lose 49.5 percent of its sandy beaches by 2100 – nearly 132,000 kilometres of coastline. Even by mid-century, the loss would be more than 40,000 kilometres. The increasingly likely RCP4.5 outlook would still see 95,000 kilometres of coastline shorn of its sand by 2100, most of it within the next 30 years.

……….In Thailand The World Bank reported nearly 40% area of the Bangkok In the future could be flooded due to heavy rains, climate change problems, and rising sea levels, as and the average soil settlement problems 1-2 centimeters per year in Bangkok also increases the severity of the problem as well. In addition to Bangkok there are other provinces that will sink as well, such as Samut Prakan, Nonthaburi, Chachoengsao, Pathum Thani, Phra Nakhon Si Ayutthaya, Suphanburi, Ratchaburi, Samut Songkhram, Samut Sakhon, Chanthaburi, Trat.
