NEW YORK, April 13 (Xinhua) -- New York City Mayor Michael Bloomberg and former U.S. President Bill Clinton announced on Wednesday the merger of their environmental groups, hoping to make it the most prominent climate policy organization in the world.The new organization would combine C40, a coalition of international cities run by Bloomberg, and the Clinton Climate Initiative, a project of Clinton' s philanthropic foundation, into a single organization, which will focus on population-rich cities to address global warming."I am elated by this. I think we really have a chance to make a difference," said Bill Clinton during a press conference at Gracie Mansion, adding that "together we are proving it is possible to create jobs and grow economies through reduced emissions."C40 and the Clinton Climate Initiative both seek to cut carbon emissions through programs that reduce energy use in buildings, promote mass transit and reuse greenhouse gases emitted by landfills.The newly combined organization is said to have a budget of about 15 million U.S. dollars. The group will have main offices in New York, Los Angeles and London.

BEIJING, Jan. 30 (Xinhua) -- As of Jan. 28, 77.4 million mu (5.16 million acres) of crops had been harmed by the ongoing drought, and 2.57 million people were faced with drinking water shortages in China, the national drought control authorities said Sunday.Local governments of the affected regions must make efforts to monitor drought conditions, speed up the building of water projects, increase drought-fighting material reserves and grant subsidies to the drought-stricken population, said officials at a meeting attended by Chen Lei, deputy head of the Office of State Flood Control and Drought Relief Headquarters (SFDH).The National Meteorological Center (NMC) forecast the drought to worsen in the next two months, saying Sunday that the drought-hit north China and regions along the Yellow and Huaihe rivers would receive little rain or snow in February and March.Chen, also minister of water resources, stressed the importance of drought relief efforts, guaranteeing agricultural production and ensuring drinking water safety for boosting consumers' confidence, controlling consumer prices and inflation and maintaining economic growth.Since last Autumn when the drought began, local authorities have assigned 9.55 million people and 2.15 million sets of drought-fighting machineries to draw 8.2 billion cubic meters of water to irrigate 110 million mu of crop land.

LOS ANGELES, April 1 (Xinhua) -- A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar is scheduled to depart Sunday, April 3 on a nine-day mission to image Hawaii volcanoes, the Jet Propulsion Laboratory (JPL) announced on Friday.The aircraft will fly from the Dryden Aircraft Operations Facility in Palmdale, California to the Big Island of Hawaii to study the Kilauea volcano that recently erupted, said JPL in Pasadena, Los Angeles.The mission will help scientists better understand processes occurring under Earth's surface, JPL said.Developed by JPL, the Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, uses a technique called interferometric synthetic aperture radar that sends pulses of microwave energy from the aircraft to the ground to detect and measure very subtle deformations in Earth's surface, such as those caused by earthquakes, volcanoes, landslides and glacier movements.As the Gulfstream-III flies at an altitude of about 12,500 meters, the radar, located in a pod under the aircraft's belly, will collect data over Kilauea, according to JPL.The UAVSAR's first data acquisitions over this volcanic region took place in January 2010, when the radar flew over the volcano daily for a week. The UAVSAR detected deflation of Kilauea's caldera over one day, part of a series of deflation-inflation events observed at Kilauea as magma is pumped into the volcano's east rift zone.This month's flights will repeat the 2010 flight paths to an accuracy of within 5 meters, or about 16.5 feet, assisted by a Platform Precision Autopilot designed by engineers at NASA's Dryden Flight Research Center on Edwards Air Force Base, California, JPL said.By comparing these camera-like images, interferograms are formed that reveal changes in Earth's surface, said JPL.Between March 5 and 11, 2011, a spectacular fissure eruption occurred along the east rift zone. Satellite radar imagery captured the progression of this volcanic event."The April 2011 UAVSAR flights will capture the March 2011 fissure eruption surface displacements at high resolution and from multiple viewing directions, giving us an improved resolution of the magma injected into the east rift zone that caused the eruption," said JPL research scientist Paul Lundgren."Our goal is to be able to deploy the UAVSAR on short notice to better understand and aid in responding to hazards from Kilauea and other volcanoes in the Pacific region covered by this study," Lundgren added.

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.

BEIJING, March 18 (Xinhuanet) --In February this year, Chinese National Geographic magazine published a series of exquisite pictures about Shicheng City (literally, Lion City), and since then, the public's strong interest in the city has been aroused again.The city of nearly 1,339 years of age, situated in east China's Zhejiang Province, has been submerged under Qiandao Lake since 1959 for the construction of the Xin'an River Hydropower Station.International archeologists vividly named the city submerged in water "time capsule." Since it is shielded from the erosion by wind, rain and sun, a city submerged in water comparatively maintains a stable condition, thus making the city a virtual time vessel. Seen from the pictures of Shicheng City, stairs in ancient houses, walls and memorial arches remain the same as they were thousands of years ago.Shicheng City was named after the Wu Shi Mountain (literally, Five Lion Mountain) in the northern part of Sui'an County, Zhejiang. It was once the center of politics, economics and culture of Sui'an County in that area.As written in the "History of Sui'an County," there are all together 265 arches submerged under Qiandao Lake, among which the Jie Xiao Memorial Arch's fine carvings remain well-preserved.According to the restored map of Shicheng, there were five city gates in all directions. You can find one city gate tower on each city gate and all together there are five towers. Besides, six streets in Shicheng City were used to connect every corner of the city as a whole. The typical roads in Shicheng City were stone roads, tidily paved by flagstone and pebbles.
