Gradually rising sea levels caused by global warming over the past 30 years have contributed to a growing number of disasters along China’s coast, state news agency Xinhua said on Wednesday. Sea levels along China’s coastline had risen 2.6 mm per year over the past three decades, Xinhua said, citing documents from the State Oceanic Administration. Average air and sea temperatures in coastal areas had risen about 0.4 and 0.2 degrees Celsius respectively over the past 10 years, the news agency added. “As a ‘gradual’ marine disaster, the cumulative effect of rising sea levels could ‘aggravate storm tides, coastal erosion, seawater invasion and other disasters’,” Xinhua cited the oceanic administration as saying. An expert at the administration, Liu Kexiu, said the rising sea levels were a result of global warming.
