LOS ANGELES, April 18 (Xinhua) -- Sugarcane has the effect of cooling temperatures, thus playing role in stemming global warming, a new study has found.Sugarcane does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants " exhale" cooler water, according to the study conducted by researchers at the Carnegie Institution's Department of Global Ecology.The researchers used data from hundreds of satellite images over 733,000 square miles (about 1,173 square kilometers) in Brazil, where sugarcane is widely grown. They measured temperature, reflectivity (also called albedo), and evapotranspiration -- the water loss from the soil and from plants as they exhale water vapor.The findings showed that expansion of sugarcane in areas previously occupied by other Brazilian crops cools the local climate.Converting from natural vegetation to crop/pasture on average warmed the cerrado by 2.79 Fahrenheit (1.55 Centigrade, but that subsequent conversion to sugarcane, on average, cooled the surrounding air by 1.67 Fahrenheit (0.93 Centigrade), the researchers said in the study published in the April issue of Nature Climate Change."We found that shifting from natural vegetation to crops or pasture results in local warming because the plants give off less beneficial water. But the bamboo-like sugarcane is more reflective and gives off more water -- much like the natural vegetation," said lead researcher Scott Loarie. "It's a potential win-win for the climate -- using sugarcane to power vehicles reduces carbon emissions, while growing it lowers the local air temperature."Brazilians are world leaders in using biofuels for gasoline. About a quarter of their automobile fuel consumption comes from sugarcane, which significantly reduces carbon dioxide emissions that otherwise would be emitted from using gasoline.The researchers emphasized that the beneficial effects are contingent on the fact sugarcane is grown on areas previously occupied by crops or pastureland, and not in areas converted from natural vegetation. It is also important that other crops and pastureland do not move to natural vegetation areas, which would contribute to deforestation.So far most of the thinking about ecosystem effects on climate considers only impacts from greenhouse gas emissions. But according to co-researcher Greg Asner, "It's becoming increasingly clear that direct climate effects on local climate from land-use decisions constitute significant impacts that need to be considered core elements of human-caused climate change."

BEIJING, Feb. 13 (Xinhua) -- Snow fell again in Beijing Saturday night, three days after the city had its first snow this winter.Snow continued falling on Sunday morning but was forecasted to stop in the daytime.From 8:00 p.m. Saturday to 8:00 a.m. Sunday, precipitation in Beijing averaged 1.7 mm to 3.1 mm in downtown areas, local meteorologists said.Zhang Qiang, head of the municipal artificial weather intervention office, said the office began cloud seeding and was continuing efforts to increase snowfall from 7:25 p.m. Saturday in the nine districts and counties of Miyun, Mentougou, Yanqing, Haidian, Pinggu, Changping, Shijingshan, Fangshan and Huairou.By 8:20 a.m. Sunday, 657 silver iodide rods had been used to increase the snowfall.More than 3,583 people and 768 vehicles have been mobilized since Saturday to clear the snow on major roads of Beijing to ensure road transportation, according to the city transportation departments.Beijing had its first snow of the winter Wednesday and Thursday after 108 days of zero precipitation.Meteorologists said the snowfall in Beijing had helped ease the pressure of drought."Beijing is expected to have another cold front from Feb. 15 to Feb. 16, but it is not sure if there will be another snowfall then," said Liao Xiaonong, chief weatherman with the Beijing Meteorological Bureau.

The severe water shortages have become a major bottleneck to our sustainable development. Nearly two-thirds of the cities in China lack water," said Chen Lei, Minister of Water Resources.From 2011 to 2015, China will strive to limit its annual water consumption within 620 billion cubic meters and cut water consumption per 10,000 yuan of GDP by 30 percent.

SHENYANG, Feb.3, (Xinhua) -- Fire gutted Thursday a five-star hotel in Shenyang, capital of northeast China's Liaoning Province, and no casualties had been found, local officials said.The fire broke out at 0:13 a.m. at Tower B, an apartment building of the Dynasty Wanxin building complex, and the flames quickly spread to the adjacent Tower A, which is largely a five-star hotel.All the 50-odd people in the hotel were evacuated. No casualties are found.The fire was effectively controlled, Shenyang Municipal Public Security Bureau officials told Xinhua at 4:35 a.m..Police said the fire was triggered by fireworks, which accidentally sparked off the external wall of the buildings. Further investigation into the cause and losses of the fire is still underway.Fire engines, whose water guns could jet water only 50 meters high, were helpless at the fire which flamed on the top of Tower A, 219 meters high.Power supply in the hotel was not cut off, which was said to keep the automatic spray facilities in operation in the building.Personnel from adjacent five-star Sheraton Shenyang Lido Hotel were evacuated, and residents around the Dynasty Wanxin building mainly stayed at home.Top leaders of the province and the city, including Chen Haibo, mayor of Shenyang, arrived at the site soon afterwards to direct efforts to quell the fire.The Dynasty Wanxin building complex, located in the bustling Qingnian Street of Heping District, comprises of three towers. The fire engulfed Tower A and B, with Tower C intact.
