LOS ANGELES, April 17 (Xinhua) -- Global warming will melt all the ice in the Arctic Ocean every summer, raising earth temperatures even further, researchers at the University of California-Los Angeles (UCLA) warned.The findings, available online Sunday in the April issue of Earth and Planetary Science Letters, a leading journal in geoscience, were based on analysis of the fossilized remains of four-million-year-old mollusks, they said.Two novel geochemical techniques used to determine the temperature at which the mollusk shells were formed suggest that summertime Arctic temperatures during the early Pliocene epoch (3.5 million to 4 million years ago) may have been a staggering 18 to 28 degrees Fahrenheit warmer than today, the researchers said.And these ancient fossils, harvested from deep within the Arctic Circle, may have once lived in an environment in which the polar ice cap melted completely during the summer months, according to the researchers.Such balmy polar weather would certainly melt all the ice in the Arctic Ocean every summer, said Aradhna Tripani, an assistant professor at the UCLA's departments of Earth and space sciences."Our data from the early Pliocene, when carbon dioxide levels remained close to modern levels for thousands of years, may indicate how warm the planet will eventually become if carbon dioxide levels are stabilized at the current value of 400 parts per million," she said.The earth's temperature was raised five to nine degrees Fahrenheit merely by the absence of year-round Arctic ice, according to Tripani.The results of the study lend support to assertions made by climate modelers that summertime sea ice may be eliminated in the next 50 to 100 years, which would have far-reaching consequences for Earth's climate, she said."The Intergovernmental Panel on Climate Change identifies the early Pliocene as the best geological analog for climate change in the 21st century and beyond," said Tripati. "The climate-modeling community hopes to use the early Pliocene as a benchmark for testing models used for forecasting future climate change."

LOS ANGELES, March 5 (Xinhua) -- Law enforcement agencies are now using smart phones to track and arrest graffiti vandals in Los Angeles, a newspaper report said on Saturday.The graffiti-tracking program, spearheaded by the Tracking and Automated Graffiti Removal System, or TAGRS, allows graffiti- cleaning crews equipped with smart phones to photograph the markings and upload them to a Los Angeles Police Department (LAPD) database, the Los Angeles Times said.The photos are used to gather evidence for prosecution and restitution, the paper quoted city officials as saying.Once the graffiti suspects' identities are discovered, the information is added to the TAGRS database and may eventually uncover incidents involving the same suspects, the paper said.The LAPD launched a pilot project in 2009 in Van Nuys near Los Angeles, modeling its version on one run by the Orange County Sheriff's Department, according to the report.The program is now anchored at four LAPD stations, Van Nuys, Hollenbeck, Central and Harbor, said Mayor Antonio Villaraigosa's spokeswoman Casey Hernandez.Los Angeles spends about 10 million dollars a year cleaning up graffiti, Hernandez said.

NEW DELHI, March 16 (Xinhua) -- The Indian government has ordered food originating from Japan to be tested for radiation in the wake of explosions at a Japanese nuclear plant following a devastating earthquake-tsunami last Friday, reported local media Wednesday.Authorized officers of Food Safety and Standards Authority of India (FSSAI) at Indian ports, airports have been asked by the government to get food originating from Japan after March 11, 2011 to be tested for radiation, according to Press Trust of India.The Department of Revenue, Government of India, has also been requested to advise all the customs points in the country where imported food is cleared, to test samples on similar lines, according to the report.

BEIJING, Feb. 2 (Xinhua) -- From dumplings in the north and rice cakes in the south, people across China Wednesday overloaded their tables with holiday foods, cheering for the Spring Festival family reunion and praying for a better life in the coming Year of Rabbit.In a remote village in Guizhou Province, villagers were sharing millet cakes and preserved pork as sunshine dispelled cold and sleet, which have plagued China's southwest for a month."This year's Spring Festival is especially cheerful, since our dream of a new home has come true," said villager Zhang Jiuyun.Zhang's home was severely damaged in the snow and sleet disaster, but with the help of local villagers and funds from the government, Zhang built a larger house without spending much money.The Spring Festival is also an important occasion for migrant workers to enjoy family reunions after toiling for higher incomes in wealthy coastal provinces for a year."I've brought back red wine and cookies imported from Italy as gifts for my parents," said Ding Zhenghe, a Shenzhen-based factory owner who has worked his way up from a migrant worker.But Ding said, after years in the modern city, he still yearns for the the food cooked by his mother in the rural home.The Spring Festival, which falls on Thursday, also marks the start of the Year of the Rabbit. It is a time for family dinners, gift giving and fireworks.Nangkun Tashi, a villager in the earthquake-hit Yushu, northwest China's Qinghai Province, celebrated the first Lunar New Year after the disaster with traditional Tibetan food, such as mutton and butter tea.A 7.1-magnitude earthquake jolted Yushu in April 2010, killing about 2,200 people and leaving Tashi's village in ruins.Tashi's family narrowly survived the quake, and have recently moved into a new home, which was provided by the local government two months before.In Zhouqu County, Gansu Province, 990 tons of grains have been delivered to the 473 survivors, who now lived in temporary housing after a massive landslide leveled the county, leaving over 1,500 people dead in August."We are able to hold a celebration, even though we've lost everything in the landslide," said local resident Yao Shelin."We've received flour, cooking oil, and even the wok is a donation," said Yao.

MADRID, Jan. 24 (Xinhua) -- The Spanish branch of Industrial and Commerce Bank of China (ICBC) was officially inaugurated in Madrid Monday.ICBC President Jiang Jianqing, Spanish Minister of Industry, Tourism and Commerce Miguel Sebastian and Chinese Ambassador to Spain Zhu Bangzao attended an inaugural gala dinner here.In a speech, Jiang thanked the Spanish government and authorities for allowing the ICBC to open in Spain and highlighted the importance of the Spanish economy and the close relations between the two countries.Sebastian said Spain welcomes the arrival of the biggest Chinese bank, which would further improve the already good relationship between the two counties.The Madrid branch is to provide a wide range of financial services to 166,000 Chinese nationals living in Spain.ICBC has a total of 386,723 employees and 162 foreign branches throughout the World.
