China News Service, March 3, according to the British "Guardian" reported that the latest research shows that due to the impact of climate change caused by coastal floods and human activities, by the end of this century, nearly half of the world's beaches will be significantly degraded.
Wind and sand erosion is reported to endanger wildlife and coastlines, or endanger coastal settlements that will lose their buffers and protect them from rising sea levels and storm surges.
Scientists from the European Commission's Joint Research Centre (JRC) have predicted from satellite images that wind erosion will destroy 36,097 km (13.6%) of the sandy coastline in 30 years. This situation will worsen in the second half of this century, further destroying 95061 km (25.7%) of the Earth's beaches.
The report said that these forecasts are relatively optimistic and are based on the immediate action of the international community to combat climate change. In this case, if melting of the ice sheet decreases and hydrothermal expansion gradually decreases, global sea level will rise by about 50 cm by 2100.
However, according to estimates by the Intergovernmental Panel on Climate Change, if the world continues to emit carbon dioxide at its current rate, the sea level of the earth will rise by 80 centimeters by 2100. If this happens, about 131,745 kilometers of beaches, or 13% of the ice-free coastline, will be submerged.
But experts say rapid action to limit carbon emissions could help reduce the impact of climate change. Experts said that if carbon emissions are moderately reduced, by 2050, people may prevent 17% of coastline degradation, and by 2100, they may prevent 40% of coastline degradation.
