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, Nov. 22 (Xinhuanet) -- Global AIDS deaths and new HIV infections have each dropped 21 percent since the peak of the AIDS pandemic in 1997, according to a UN report released Monday.One major factor responsible for the result is that life-saving HIV treatments have become more popular and got to 1.35 million more people in 2010 than in 2009.In middle-income and underdeveloped nations, these treatments have saved 2.5 million lives since 1995."We have seen a massive scale-up in access to HIV treatment, which has had a dramatic effect on the lives of people everywhere," said Michel Sidibe, executive director of the U.N. AIDS program.However, 53 percent of people who need HIV/AIDS treatments -- about 7.6 million people -- cannot get them, which accounted for 1.8 million AIDS deaths in 2010.There are now 34 million people living with HIV. And just in last year there were 2.7 million new infections.The decline in deaths and new infections means the AIDS pandemic is at a turning point, the UNAIDS report argues, adding smart investment can save millions of future deaths.

BEIJING, Jan. 3 (Xinhua) -- A collection of China's nine white papers issued in 2011 has been published in both Chinese and English, according to a statement issued by the publisher on Tuesday.By giving a clear and precise illustration of China's policies, principles and progress in subjects like national defense, law, climate change and international trade, the white papers can help the world know about, and understand, China, the statement said.The white papers are titled, "China's National Defense in 2010," "China's Foreign Aid," "Sixty Years Since the Peaceful Liberation of Tibet," "China's Peaceful Development," "The Socialist System of Laws with Chinese Characteristics," "New Progress in Development-oriented Poverty Reduction Program for Rural China," "China's Policies and Actions for Addressing Climate Change (2011)," "China's Foreign Trade" and "China's Space Activities in 2011."The white papers were all published by the Information Office of the State Council on behalf of the Chinese government.The latest one on space activities was issued last Thursday.

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.

BEIJING, Jan. 9 (Xinhua) -- China's official website for booking train tickets received a daily average of more than 1 billion hits during the first week of January, according to a railway official.Hu Yadong, vice minister of railways, said Sunday that the online ticket sales platform has provided consumers with a convenient way to buy tickets. He also addressed complaints about the fairness of the sales process."Train tickets sold online or by telephone have topped 2 million daily, meaning that around one-third of passengers don't have to wait in line at train stations for several hours to get a ticket," Hu said.However, many Chinese have expressed dissatisfaction with the website, with some people unable to get train tickets home for this year's Spring Festival holiday, a major holiday in China.Several customers posted their complaints on popular microblogging website weibo.com, stating that the booking site often failed due to "too many visits at the same time."The Spring Festival holiday is always a difficult time for China's public transportation authorities. A total of 3.16 billion passenger trips are expected during the holiday, up 9.1 percent from a year earlier, of which 235 million trips will be made via the country's railways, up 6.1 percent year-on-year, said Hu.This year's transport rush in the Spring Festival Season started on Sunday and will end on Feb. 16, according to the Ministry of Railways.
