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.

SAN FRANCISCO, Oct. 5 (Xinhua) -- Microsoft announced Wednesday that it will bring cable television content to its Xbox video game console over the upcoming holiday season, expanding the console into an entertainment hub.According to the company's press release, nearly 40 world- leading TV and entertainment providers such as HBO GO and BBC will stream their content through the Xbox Live service in more than 20 countries and regions.Users will be able to sift through shows online with the Kinect motion sensor device for Xbox 360 and Bing voice search, Microsoft said.To watch TV programs via Xbox as an alternate delivery system, customers have to already subscribe to the TV services and Microsoft's Xbox Live Gold service of 60 U.S. dollars per year."Today's announcement is a major step toward realizing our vision to bring you all the entertainment you want, shared with the people you care about, made easy," Microsoft said in the press release.Microsoft first entered the gaming console market in 2001 with the Xbox, the predecessor to the Xbox 360. The Xbox 360 currently competes with Sony's PlayStation 3 and Nintendo's Wii as the seventh generation of video game consoles.In June, Microsoft said 35 million people subscribed Xbox Live service around the world, spending an average of 60 hours a month playing games and watching movies and shows. Last year, the company integrated social networking features into Xbox Live, allowing users chat with each other while watching programs.

SAN FRANCISCO, Nov. 14 (Xinhua) -- Google is running a secret research lab in the San Francisco Bay Area, where the tech giant invests to experiment and invent what may be world-changing technologies for the future, U.S. media reported on Monday.According to The New York Times, at the lab dubbed Google X, engineers are working at some 100 projects from robots, smart refrigerators to Internet-enabled dinner plates and a "space elevator," a proposed non-rocket space launch structure.An unnamed Google engineer familiar with the lab told the newspaper that it was run as mysteriously as the CIA with two officers, a nondescript one for logistics on the company's Mountain View campus and one for robots in a secret location.Scientists working at the lab include many roboticists and electrical engineers hired from Microsoft, Nokia labs, Stanford, MIT, Carnegie Mellon and New York University. Google's co-founder Sergey Brin is said to be "deeply involved" in Google X.The lab is reportedly headed by Sebastian Thrun, one of the world's top robotics and artificial intelligence experts. He teaches computer science at Stanford University and invented the world's first self-driving car.A Google spokeswoman would not confirm the existence of the lab, but said Google likes to invest in speculative projects."While the possibilities are incredibly exciting, please do keep in mind that the sums involved are very small by comparison to the investments we make in our core businesses," she told The New York Times.
