WASHINGTON, Nov. 24 (Xinhua) -- A new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies.Authors of the study, which was funded by the National Science Foundation and published online on Thursday in the journal Science, say that global warming is real and that increases in atmospheric CO2 will have multiple serious impacts. However, the most Draconian projections of temperature increases from the doubling of CO2 are unlikely."Many previous climate sensitivity studies have looked at the past only from 1850 through today, and not fully integrated paleoclimate date, especially on a global scale," said Andreas Schmittner, an Oregon State University researcher and lead author on the Science article. "When you reconstruct sea and land surface temperatures from the peak of the last Ice Age 21,000 years ago -- which is referred to as the Last Glacial Maximum -- and compare it with climate model simulations of that period, you get a much different picture.""If these paleoclimatic constraints apply to the future, as predicted by our model, the results imply less probability of extreme climatic change than previously thought," Schmittner added.Scientists have struggled for years trying to quantify "climate sensitivity" -- which is how the Earth will respond to projected increases of atmospheric carbon dioxide. The 2007 IPCC report estimated that the air near the surface of the Earth would warm on average by two to 4.5 degrees (Celsius) with a doubling of atmospheric CO2 from preindustrial standards. The mean, or " expected value" increase in the IPCC estimates was 3.0 degrees; most climate model studies use the doubling of CO2 as a basic index.The researchers based their study on ice age land and ocean surface temperature obtained by examining ices cores, bore holes, seafloor sediments and other factors. When they first looked at the paleoclimatic data, the researchers only found very small differences in ocean temperatures then compared to now."Our study implies that we still have time to prevent that from happening, if we make a concerted effort to change course soon," said Schmittner.

BEIJING, Jan. 25 (Xinhua) -- China's railway authorities said Wednesday that it would put 315 more trains into service on Wednesday to cope with Lunar New Year travel demand, compared with 159 on Tuesday.About 3.7 million passengers hit the rails on Tuesday, up from 2.29 million on Monday, the Ministry of Railways said in a statement on its website.The ministry expected a post-festival travel peak on Friday.The country's trains carried a total of 83.46 million passengers from Jan. 8 to 22, up 7.9 percent from a year earlier, the ministry said in a statement issued on Tuesday.The 40-day Spring Festival travel season kicked off on Jan. 8 this year, with hundreds of millions of people, mainly migrant workers and college students, heading home for the most important festival in China.A total of 3.16 billion passenger trips are expected during the year's travel rush, up 9.1 percent from a year earlier. Of those journeys, 235 million are likely to be made by train, up 6.1 percent year-on-year.The Spring Festival, or Chinese Lunar New Year, falls on Jan. 23 this year. 

WASHINGTON, Nov. 21 (Xinhua) -- The use of acupuncture for children is common and acupuncture is generally safe for children when performed by "appropriately trained practitioners," Canadian researchers reported Monday in online journal Pediatrics.Researchers at the University of Alberta looked at data from 37 studies of needle acupuncture, spanning 60 years, on children from birth to age 17, and assessed the association between needle acupuncture and various levels of adverse events in children. They found that of 279 adverse events identified, 253 were mild, one was moderate and 25 were serious.Serious side effects included bleeding, infections, and heart and lung problems. One child may have contracted HIV. But the researchers said the serious side effects were related to substandard conditions from the care provider, rather than acupuncture's technique itself. They concluded that in trained hands, pediatric acupuncture is safe.Acupuncture has been around for thousands of years, and traditional Chinese theory suggests needle placement helps balance the body's energy flow, called "qi". Acupuncture is sometimes used to treat headaches, migraines, back and joint pains, cramps, and chemotherapy-induced nausea. Estimates show 150,000 U.S. children undergo acupuncture each year.

BEIJING, Dec. 14 (Xinhua) -- Chinese President Hu Jintao on Wednesday exchanged congratulatory messages with Cypriot President Demetris Christofias on the 40th anniversary of bilateral diplomatic ties.In his message, Hu said bilateral ties between China and Cyprus have developed smoothly since they were established.Political mutual trust has continued to deepen and the two countries understand each other and support each other's major concerns, he said, adding bilateral pragmatic cooperation has also been expanding continuously.China highly values its relations with Cyprus and is ready to work with the country to deepen their traditional friendship, strengthen exchanges at various levels and enhance cooperation in such areas as economy, trade, culture and tourism, the Chinese president said.Hu said China is also willing to maintain communication and coordination with Cyprus on international and regional affairs.Christofias, for his part, said China and Cyprus have carried out close exchanges and cooperation, adding bilateral ties have been further strengthened through frequent high-level exchanges in recent years.Cyprus believes the two countries are on friendly terms and understand each other, which is in line with the common interests of both China and Cyprus, Christofias said.The president said Cyprus also believes bilateral relations would make further progress in the future.Chinese Foreign Minister Yang Jiechi also exchanged congratulatory messages on Wednesday with his Cypriot counterpart Erato Kozakou Marcoullis.

BEIJING, Oct. 26 (Xinhua) -- The central government allocated 935 million yuan (147 million U.S. dollars) Wednesday to areas hit by rain-triggered floods, the Ministry of Civil Affairs (MCA) said.The relief funds, jointly allocated by the MCA and the Ministry of Finance, will be used for disaster survivors to relocate, rebuild houses and buy daily necessities.The funds will also be delivered to the family members of the victims, according to the ministry.The funds will go to the flood-hit provinces of Shanxi, Henan, Hubei, Sichuan, Shanxi and Guangxi Zhuang Autonomous Region.The government already allocated 132 million yuan (20.6 million U.S. dollars) to disaster hit areas immediately after the floods happened in September.Rain-triggered floods and disasters left 97 people dead, 21 missing and 1.23 million affected in September in China's 11 provincial-level regions, and a total of 1.93 million people were relocated urgently to avoid further casualties.The disasters also caused an estimated 21 billion yuan (3.29 billion U.S. dollars) in direct economic losses, according to official data.
