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, Dec. 14 (Xinhua) -- The People's Bank of China, the country's central bank, said Wednesday that China will continue its prudent monetary policy next year while making the policy more targeted, flexible and forward-looking.The announcement came after the conclusion of the annual central economic work conference Wednesday morning, which has set economic policy guidelines for the coming year.The central bank will maintain control over the intensity, pace and focus of macroeconomic regulation, make full use of monetary tools, tune up credit supply and promote reasonable growth in social financing, according to a statement posted on its website.The bank will improve credit structure, increase support to key sectors and weak areas, especially to agriculture, small and medium-sized enterprises and affordable housing construction, as well as better serve the real economy.It will continue to perfect its yuan exchange rate formation mechanism, and keep the yuan exchange rates basically stable at a reasonable and balanced level.Meanwhile, the bank will strengthen and improve its foreign exchange management, deepen financial system reforms, prevent and solve financial risks, the statement said.

BERLIN, Jan. 17 (Xinhua) -- Researchers in Germany have found a cheap and easy way to synthesize anti-malaria drug in large quantities from waste materials, said the Max Planck Society on Tuesday.Currently there are nearly one million people die worldwide each year due to lack of effective drugs, as sweet wormwood, from which artemisinin, the effective essence to fight malaria can be extracted, only grows in China, Vietnam and a few other countries.However, researchers in Germany have now developed a simple process for the synthesis of artemisinin in laboratory, using artemisinic acid, a substance contained in the by-product, or waste materials of the isolation of artemisinin from sweet wormwoods, as row materials of synthesizing artemisinin."The production of the drug is therefore no longer dependent on obtaining the active ingredient from plants," said Peter Seeberger, director at the Max Planck Institute of Colloids and Interfaces in Potsdam and professor at Free University of Berlin.The artemisinic acid in the waste material boasts a volume 10 times greater than the active ingredient itself, said Seeberger, and they could be turned into artemisinin in four and a half minutes in a so-called continuous-flow reactor.Seeberger estimated that 800 of the reactors would be enough to cover the global requirement for artemisinin, and the whole innovative synthesis process could be ready for technical use in three to six months.Malaria is a disease caused by parasites that are transmitted to people through the bites of infected mosquitoes. In 2010, malaria caused an estimated 655,000 deaths, mostly among African children.

RIO DE JANEIRO, Dec 15 (Xinhua) -- Brazilian President Dilma Rousseff Thursday signed a law banning smoking in public spaces and tobacco advertising at sale places in his country.Smoking in all enclosed public spaces, defined as free access areas used simultaneously by several people, is forbidden in the new law.It also prohibits tobacco advertising such as posters or banners at sale places. Previously the ban was only imposed on TV, radio and billboards advertising.In addition, the law increases the taxes and establishes minimum prices over the tobacco products to discourage buyers, therefore the cigarettes prices are expected to increase 20 percent in 2012 and 55 percent by 2015.Health warnings are also required on both sides of cigarette packs to alert consumers about the consequences of their smoking habit.The law is welcomed by some anti-smoking groups."In addition to protecting the health of its citizens, Brazil has also set an example for the world," said Matthew Myer, president of Campaign for Tobacco-Free Kids.

BEIJING, Dec. 16 (Xinhua) -- China issued rules for pilot programs of RMB Qualified Foreign Institutional Investors (RQFII) on Friday, formally giving a green light to investment of overseas RMB funds in mainland securities markets.The move is expected to widen the investment channel of overseas RMB funds and add new momentum to the country's bid to make the RMB an international currency.Hong Kong subsidiaries of fund management companies and securities firms can use RMB funds raised in Hong Kong to invest in mainland securities within a permitted quota, according to the rules jointly released by the China Securities Regulatory Commission (CSRC), the People's Bank of China and the State Administration of Foreign Exchange.The total investment quota of RQFII pilot programs is set at around 20 billion yuan (3.15 billion U.S. dollars), according to the rules.To control risks, qualified investors should invest no less than 80 percent of the RMB funds they raised in fixed-income securities, while investment in stocks and equity funds should account for no more than 20 percent.The CSRC will join other related departments to study the possibility of further expanding the trial program after its launch, said a CSRC official who declined to be identified.The launch of the RQFII will open another significant channel for overseas RMB funds to flow back into the country, said the CSRC official.It will also help diversify investment products for overseas RMB funds and facilitate off-shore RMB business, the official said.The RMB is not fully convertible under the capital account but China has stepped up efforts to make the currency more international over the past few years.The government has encouraged the use of the RMB in cross-border trade and investment settlement and approved foreign direct investment in overseas RMB funds obtained overseas.It also allowed Hong Kong to establish an offshore yuan market and has expanded trade settlement agreements and currency swaps to create more channels for the yuan to circulate outside the mainland.
