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.

PARIS, Dec. 23 (Xinhua) -- French health authorities on Friday urged 30,000 women to remove the local-made breast implant, pledging that relevant expenses would be covered by the state.The health ministry said in a statement that they spot "no increased risk of cancer currently in women wearing the PIP (Poly Implant Prothese) brand compared with other implants.""However, well-established risks associated with these prostheses are rupture and irritant gel may lead to inflammatory reactions, making it difficult to explant," the statement added.French Health Minister Xavier Bertrand advised French women who have the PIP implants to get them taken out "as a preventive measure but not of an urgent nature." The removal of the implant will be at the state's expense.The recommendation came after eight cases, mainly breast cancer, were reported recently among women with PIP implants.The involved implant was produced by the French company PIP, once the world's third-largest producer of silicone implants who sold its products to tens of thousands of women in more than 65 countries, mainly in South America and western Europe.

BEIJING, Jan. 24 (Xinhua) -- Chinese President Hu Jintao and Premier Wen Jiabao on Tuesday exchanged congratulatory messages with their Israeli counterparts Shimon Peres and Benjamin Netanyahu on the 20th anniversary of the establishment of diplomatic ties between the two countries.Hu said the friendly exchanges between the Chinese and the Jewish people go back to ancient times.Since the forging of official ties 20 years ago, friendly cooperative ties between China and Israel have been developing continuously, and the exchanges and cooperation between the two sides in politics, economy and trade, culture, science and technology, agriculture and education have yielded fruitful results and brought tangible benefits to the two countries and the two peoples, Hu said.China attaches great importance to advancing Sino-Israeli ties and is ready to make joint efforts with Israel to take the celebration of the 20th anniversary as an opportunity to further consolidate the traditional Sino-Israeli friendship, deepen mutual cooperation in various fields, increase personnel exchanges on multiple levels, and promote a continuous development of friendly Sino-Israeli cooperative relations, he said.For his part, Peres said Israel and China established official diplomatic ties 20 years ago, which brought the friendship between the two countries to a historic high.He believed that the Israeli-Chinese friendship, which is based on a shared history, common values and ancient culture and tradition, will prevail.Peres said his country pays great attention to its ties with China in all areas, and is willing to conduct mutually beneficial cooperation with China in science and technology and other fields.In his message, Peres wished the Chinese people a "Happy New Year" in the Year of the Dragon.On the same day, Chinese Premier Wen also exchanged congratulatory messages with Israeli Prime Minister Netanyahu.Wen said their bilateral friendly cooperative relations have continued to grow over the last 20 years.Political exchanges between the two countries have been increasingly close, economic and trade cooperation have continued to flourish, and pragmatic cooperation in culture, science and technology, and agriculture has been fruitful, Wen said.China and Israel have their own advantages, as well as huge potential and broad prospects for cooperation, the Chinese premier said.China is ready to continue to expand and deepen its friendly bilateral cooperation with Israel and raise Sino-Israeli ties to a new high, Wen said.For his part, Netanyahu said the Chinese and the Jewish people have always been friends.During the past 20 years, China and Israel succeeded in forging a stable and diversified partnership, he said.The Israeli side is ready to fully explore the potential of bilateral ties and continue to expand cooperation in science and technology, sanitation, agriculture and environmental protection technologies and other fields with China, Netanyahu said.He believed that there will be more opportunities to further consolidate the friendship between the two peoples and deepen bilateral cooperation in the future.Chinese Foreign Minister Yang Jiechi and Israeli Foreign Minister Avigdor Lieberman also exchanged congratulatory messages.

BEIJING, Oct. 24 (Xinhuanet) -- The average global land temperature has increased by around one degree Cetigrade since the mid-1950s, American scientists announced last week after reviewing historical temperature records to date.According to media reports, the scientists of the Berkeley Earth project have studied more than a billion temperature records dating back to the 1800s from 15 sources around the world.And the result is in line with the estimate made by major institutions which keep official records on the global climate, including the Nasa's Goddard Institute for Space Studies in the US and the Met Office's Hadley Centre in Britain.Meanwhile, the scientists established an open database for the climate records so that skeptics on climate change can assess climage change on their own.Nevertheless, the finding of the scientists at the University of California, Berkeley did not convince climate change skeptics, according to a New York Times report.Anthony Watts, one prominent US skeptics, claimed the study's "methodology was flawed". He also noted that the finding was submitted to journal Geophysical Research Letters before being peer-reviewed.Richard Muller, a physicist and head of the project, argued that the decision to circulate the papers before publication was part a long-standing academic tradition of sanity-checking results with colleagues.He added, cited by the Guardian, "We will get much more feedback from making these papers public before publication."

BEIJING, Oct. 25 (Xinhuanet) -- Steve Jobs, Apple's co-founder and former CEO, may be one of the great men who will still be influential after their deaths.The new biography of Steve Jobs is likely to be the top-selling book 2011 of Amazon.com Inc, an online book retailer, according to Amazon spokeswoman Brittany Turner Monday."It could very likely be our top-selling book of the year," Turner said in a statement cited by the Reuters.Steve Jobs, written by Walter Isaacson, former Time magazine managing editor, was landed on shelves in bookstores Monday.But its digital version was reported to be released late on Sunday on Apple's iBooks online store and Amazon's Kindle eBook store.Since its release, the biography, both electronic and physical versions, has performed very well in Amazon.It is the best-selling book on Amazon.com and the top-selling electronic book on the Kindle as well. According to the Reuters, Isaacson was asked by Jobs to consider writing a biography for Apple's former CEO in 2004, when Jobs was going to be operated on for pancreatic cancer.Then Isaacson had more than 40 exclusive interviews with Steve Jobs. The last such interview was on October 5, one week before the giant's death.
