The China Meteorological Ad-ministration (CMA) Tuesday announced the completion of a national climate observation network to help mitigate global warming.CMA director Zheng Guo-guang said the network would collect accurate information about climate change."Climate change is threatening the environment, state security and economic development," Zheng said.Responding to a UN plan, China's first climate observation network was set up in 1997. Seven departments - meteorology, water affairs, agriculture, environmental protection, forestry, ocean and scientific research - joined the network.The network set up 16 key observation areas, Zhang Renhe, director of the Chinese Academy of Meteorological Sciences Director, said.These are: Atmosphere and land systems in the Qinghai-Tibetan plateau, glacier; water and ecological systems in the Tianshan Mountain area; Xilingol pastures in the Inner Mongolia Autonomous Region; Dunhuang desert in Gansu Province; forests in Northeast China; water circulation systems in Sichuan and Yunnan provinces; agriculture in the Yellow and Huaihe river basins; the lakes of Dongting and Poyang; the atmosphere around Mount Waliguan in Qinghai Province; ecological systems in source regions of the Yangtze, Yellow and Lancang rivers; the economic belt around Beijing; economic development zones in the Yangtze and Pearl river deltas; Sichuan Basin; the land-ocean-atmosphere system around Bohai Sea; air-sea interaction in the South China Sea; and comprehensive oceanic observations.By observation and data processing, the network should provide data about temperatures, glaciers, frozen soil, accumulated snow, aerosoles, greenhouse gases, ozone, plant and soil."This data can help China predict natural disasters, strengthen forecasts of extreme weather events and be more adaptable when it comes to industrial projects," Zheng said.A National Climate Change Program was released in June, which pledged to cut greenhouse gas emissions, but with no specific goals.

BEIJING - Chinese central government offices suffered a day without air-conditioning as they warmed to a campaign to cut energy consumption and improve energy efficiency, Xinhua news agency said on Wednesday. Tuesday's campaign, dubbed "experiencing energy shortage", targeted offices and government departments under the State Council, the nation's cabinet. "Beijing was not as sun-burning as previous days on Tuesday, but the overcast weather still made people sweat in the afternoon," Xinhua said. China's capital has unleashed "energy police" to enforce limits on air-conditioner use as the government pushes to save power and clean polluted skies, state media said this week. China last year vowed to cut energy consumption for every unit of economic activity by 20 percent by the end of 2010. But feverish economic growth has so far defied the target. The government's latest weapon is 22 officials who will check whether offices, hotels, malls and other big buildings in Beijing are observing a demand to set air conditioning no cooler than 26 degrees Celsius (79 Fahrenheit), the Beijing News reported. Worried that the nation cannot sustain resource-sapping growth, the central government has repeatedly ordered officials and companies to save energy. Efforts to clear the capital of pollution have taken on a new urgency with the 2008 Beijing Olympics just over a year away. Chinese President Hu Jintao and other officials have said the country is committed to emission reduction, but refused mandatory caps. Beijing has held up its voluntary energy saving measures as an important contribution to fighting global warming, and called for more technological help for clean energy.

SHENZHEN -- Construction began Saturday on an experimental facility which will offer a platform for Chinese and foreign scientists to work together for discovering a new kind of neutrino oscillation in Shenzhen, South China's Guangdong Province.It was the second biggest cooperation program Chinese high energy scientists ever conducted with other foreign counterparts since October 1988 when the positive-negative electron collider was built in Beijing.Through the collider, scientists from China and the United States have cooperated and carried out legions of scientific research.Saturday's construction commencement function was attended by more than 100 people, including government officials and foreign diplomats, such as Dr. Robin Staffin, Associate Director of Science in the US Department of Energy.Neutrino Oscillation is an intriguing behavior of a sub-atomic particle called neutrino.And the new facility is being built in the mountain near Daya Nuclear Power Plant, which has four reactors with a combined thermal output of 11.6 million kw in operation, and Ling'ao nuclear power plant is not far away. Both nuke power plants will serve as sources of anti-neutrinos for the experiments when the facility is finished.Workers will build three underground experimental halls which will be connected by long tunnels in the mountain that shields the experiment from unwanted cosmic radiation.Each hall will feature a 10-m deep water-pool within which eight anti-neutrino detectors will be deployed. The water protects the detectors from nearby radiation that interferes with the measurement, and helps identify surviving cosmic radiation.And the first experimental hall is expected to be ready by the end of 2008. Commissioning of the detectors in this hall will take place in 2009.Civil engineering construction is anticipated to last about two years, with installation of the last detector scheduled for 2010.Upon completion of the new facility, more than 190 scientists from six countries and regions including the Chinese mainland, Hong Kong, Taiwan Province, the United States and Russia will come over to do research work, according to Chen Hesheng, Chief of the Institute of High Energy Physics with the Chinese Academy of Sciences (CAS).The facility will have a budget of 250 million yuan (US.25 million). And China will be responsible for infrastructure construction and making of four detectors. And the United States will be responsible for making of the rest of the detectors.Wang Yifang, chief scientist on the experiment, said he was confident that the program would make an important contribution to finding a new breakthrough in China's research efforts in particle physics, starting a new horizon in world's neutrino research, and to improving the overall strength of China in science and technology.

Foreign trade in east China's Shanghai port rose 20.3 percent year-on-year to 91.06 billion U.S. dollars in the first two months of 2008, official statistics show.     The figure accounted for 24.9 percent of the country's total trade value of 365.93 billion U.S. dollars from January to February.     Exports climbed 17.2 percent, 20.7 percentage points lower than the period from a year earlier, to 58.59 billion U.S. dollars. Mechanical and electronics products accounted for around 60 percent of total exports.     Imports jumped 26.3 percent, 10.8 percentage points higher from the same period last year, to 32.47 billion U.S. dollars, the Shanghai Customs said.     The surplus rose 7.6 percent to 26.12 billion U.S. dollars. The rate was 66.1 percentage points lower from a year ago.     Export growth slowed as the Spring Festival holiday and the strongest winter blizzards in five decades closed factories and disrupted transport. The government policies introduced last year to reduce surging surplus also contributed to the slower pace, as shown in the steel and garment sectors.     Imports, however, accelerated their pace as China bought more commodities and farm produce at higher prices. Through the Shanghai port 549,000 tons of agricultural products were imported in the two months, an annual increase of nearly 30 percent. Their average price was up 24.7 percent from a year earlier.
