Rising sea levels and falling river water volumes - as forecast in the latest UN report on climate change - could drastically alter weather patterns and cause huge economic losses in China, a senior meteorological official warned Thursday.Luo Yong, deputy director of the Beijing Climate Center affiliated to the China Meteorological Administration (CMA), said there will be more typhoons, floods and land subsidence as a result of global warming.The report by the Intergovernmental Panel on Climate Change released in Spain last Saturday said "human activities could lead to abrupt or irreversible climate changes and impacts".It said that even if factories were shut down and cars taken off roads, the average sea level will rise up to 140 cm over the next 1,000 years from the pre-industrial period of around 1850.In the next 100 years, it said, sea levels will rise by 18-51 cm.More frequent and heavy floods require China - which has an 18,000-km coastline on the mainland - "to build coastal facilities of higher standard," Luo told a press conference.As coastal regions are economically developed areas, the loss from typhoons and floods will be magnified, Luo said.He also warned that higher sea levels will lead to further land subsidence, which is already being seen in some coastal areas.Another major threat from global warming is water shortage, Luo said.In the past 50 years, the six major rivers in the country have seen their water volumes reduced sharply, especially those in the north, such as the Yellow and Huaihe rivers. Ground water storage has also dropped markedly, he added.The water shortage will take a toll on the farming sector, hurting grain production; and industrial and domestic consumption will be affected, he said.Luo said that China will possibly see more flooding in the north and drought in the south, the reverse of the current weather pattern.Song Dong, an official from the Ministry of Foreign Affairs, said next month's international talks on global warming in Bali, Indonesia, are expected to focus on greenhouse gas cuts by rich countries and the transfer of more clean technology to developing nations.

Nanjing - Four people died and 16 were injured when a snow-laden fuel pump shelter in Nanjing suddenly collapsed on Sunday afternoon, according to local sources.The accident took place around 2:30 pm at the Sinopec Wujiang fuel pump station in Pukou District of Nanjing, the Jiangsu Province capital, when one van, one sedan and six motorbikes were refueling.The station ceiling, with a floor area of 1,430 square meters, suddenly gave way to the thick snow that had accumulated on it over the past few days. When it hit the ground, it engulfed all the vehicles and people beneath it, said information from the city government.It was not immediately known whether any station service workers were in the accident.The victims were all rescued from the debris and rushed to hospital immediately. Four later died from their injuries. The others were hospitalized.The accident is under further investigation.

CHENGDU: Thick fog continued to blanket parts of western and central China Sunday, causing traffic accidents, flight delays and highway closures.Plunging visibility from the bad weather delayed more than 150 flights and left 12,000 passengers stranded Sunday in the Shuangliu International Airport in this capital of Sichuan Province, airport officials said.The airport was closed for nearly nine hours Sunday morning before a flight to Tibet took place at 11:10 am."Full operations did not return to normal until more than an hour later when the first flight from Shenzhen in Guangdong Province landed here," airport publicity department official Liu Gang told China Daily."It was the second day visibility in the airport had been at about 10m."On Saturday morning, a heavy fog fell on Chengdu, shrouding its downtown areas and six suburban counties with a visibility of under 50m.The airport itself was closed for eight hours that day, with 121 flights delayed and 11,000 passengers stranded.Sichuan weather bureau deputy chief Zhong Xiaoping said environmental pollution was a major cause of the fog.Zhong advised citizens to take buses more often, save energy, cut car exhaust, and play a part in the recycling of waste materials.More than 10,000 vehicles were stranded from the fog on highways Sunday, about 4,000 more than the day before, the Chengdu Transportation Bureau said. It advised residents to take trains in the next few days.He Ping, a 49-year-old company employee, drove from Deyang in northern Sichuan to Chengdu through the Chengdu-Mianyang Expressway Sunday afternoon."I've driven for nearly 20 years and have never seen such heavy fog before. I could not even see the line separating the fast lane from the slow one," He told China Daily.Meanwhile, heavy fog also persisted in Hebei, Henan and Shaanxi provinces for consecutive days. The poor visibility forced highways to close and delayed flights Sunday.The Xi'an-Baoji Expressway in Shaanxi Province was closed on Saturday as visibility in some sections was less than 2m.Meteorologists also attributed the fog to a combination of high humidity, lower temperatures and low wind speeds in the affected regions.Xinhua contributed to the story

The highly anticipated Beijing-Shanghai high-speed railway will begin construction next month, a Ministry of Railways official said.The ministry source, who did not want to be named, confirmed in a phone interview yesterday that preparations are now being made for a ceremony to commence construction of the system.Based on that timeframe, the railway will be completed by 2013. Trains running on the 1,318 km railway will then be able to travel at speeds of up to 350 kph and will cut travel time between the two cities from the current 10 hours to less than five.The project involves one of the largest amounts of investment on railways. Industry sources say it will cost more than 200 billion yuan ( billion), more than the 180 billion yuan needed for the Three Gorges Project.Officials say the project will also employ a set of locally developed high-speed railway technology for the first time.The country is said to have already mastered the technologies needed to lay high-speed rail tracks and trains.The first homegrown train able to reach 300 kph rolled off the production line over the weekend, marking China's entry into "an elite club that includes Japan, France and Germany to become the fourth country capable of making such trains", Wang Yongping, Ministry of Railways spokesman said.Officials added that the railway still relies on foreign companies, such as the Germany-based Siemens, to build its signal network and other systems.China has been upgrading the scale and speed of its railway network in the past decade, and the 11th Five Year Plan period (2006-10) is regarded as a critical period for building high-speed railways that can travel at speeds of 200 kph as part of an extensive transport network.At least eight express passenger railways were being constructed as of last year.Xinhua contributed to the story

TAIYUAN -- Fifteen miners have been confirmed dead following Saturday's gas explosion in a coal mine in Linfen City, north China's Shanxi Province, rescuers said on Sunday. Rescue operation is still going on. The gas blast occurred around 1:50 p.m. on Saturday at Pudeng Coal Mine in Kecheng Township of Puxian County. About 30 miners were trapped underground, according to preliminary estimates. "The exact number of miners trapped underground is yet to be affirmed," said a spokesman for Shanxi Provincial Bureau of Coal Mine Safety Supervision. The cause of the gas explosion is being investigated. Pudeng Coal Mine, which is in operation with permits, produces 150,000 tons of coal a year. Zhao Tiechui, director of the State Administration for Coal Mine Safety Supervision, together with local officials have rushed to the accident site to direct rescue efforts.
