单选题EI Nino (厄尔尼诺现象) While some forecasting methods had limited SUCCESS predicting the 1997 El Nin a few months in advance, the Columbia University researchers say their method call predict large EI Nino events up to two years in advance. That would he good news for governments, farmers and others seeking to plan for the droughts and heavy rainfall that EI Nino can produce in various parts of the world. Using a computer the researchers matched sea-surface temperatures to later EI Nino occurrences between 1980 and 2000 and were then able to anticipate EI Nino events dating back to 1857 , using prior sea-surface temperatures. The results were reported in the latest issue of the journal Nature. The researchers say their method is not perfect, but Bryan C. Weare. a meteorologist at the University of California, Davis, who was not involved in the work, said it "suggests EI Nino is indeed predictable." "This will probably convince others to search around more for even better methods." said Weare. He added that the new method "makes it possible to predict EI Nino at long lead times." Other models also use seasurface temperatures, but they have not looked as far back because they need other data, which is only available for recent decades, Weare said. The ability to predict the warming and cooling of the Pacitic is of immense importance. The 1997 El Nino, for example, caused an estimated $ 20 billion in damage worldwide, offset by beneficial effects in other areas, said David Anderson, of the European Centre for Medium. Range Weather Forecasts in Reading England. The 1877 EI Nino, meanwhile, coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China. Prompting the development of seasonal forecasting, Anderson said. When EI Nino hit in 1991 and 1997. 200 million people were affected by flooding in China alone. According to a 2002 United Nations report. While predicting smaller EI Nino events remains tricky. The ability to predict larger ones should be increased to at least a year if the new method is confirmed. EI Nino tends to develop between April and June and reaches its peak between December and February. The warming tends to last between 9 and 12 months and occurs every two to seven years. The new forecasting method does not predict any major EI Nino events in the next two years, although a weak warming toward the end of this year is possible.

单选题Too Little for Global Warming Oil and gas will run out too fast for doomsday global warming scenarios to materialize, according to a controversial new analysis presented this week at the University of Uppsala in Sweden. The authors warn that all the fuel will be burnt before there is enough carbon dioxide in the atmosphere to realize predictions of melting ice caps and searing temperatures. Defending their predictions, scientists from the Intergovernmental Panel on Climate Change say they considered a range of estimates of oil and gas reserves, and point out that coal-burning could easily make up the shortfall. But all agree that burning coal would be even worse for the planet. The IPCC's predictions of global meltdown pushed forward the 1997 Kyoto Protocol, an agreement obliging signatory nations to cut CO2 emissions. The IPCC considered a range of future scenarios, from unlimited burning of fossil-fuels to a fast transition towards greener energy sources. But geologists Anders Sivertsson, Kjell Aleklett and Colin Campbell of Uppsala University say there is not enough oil and gas left even the most conservative of the 40 IPCC scenarios to come to pass. Although estimates of oil and gas reserves vary widely, the researchers are part of a growing group of experts who believe that oil supplies will peak as soon as 2010, and gas soon after. Their analysis suggests that oil and gas reserves combined about to the equivalent of about 3,500 billion barrels of oil considerably less than the 5,000 billion barrels estimated in the most optimistic model envisaged by the IPCC. Even the average forecast of about 8,000 billion barrels is more than twice the Swedish estimate of the world's remaining reserves. Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who headed the 80-strong IPCC team that produced the forecasts, says the panel's work still stands. He says they factored in a much broader and internationally accepted range of oil and gas estimates than the "conservative" Swedes. Even if oil and gas run out, "there's a huge amount of coal underground that could be exploited", he says that burning coal could make the IPCC scenarios come true, but points out that such a switch would be disastrous. Coal is dirtier than oil and gas and produces more CO2 for each unit of energy, as well as releasing large amounts of particulates. He says the latest analysis is a "shot across the bows" for policy makers.

单选题Longer Lives for Wild Elephants Most people think of zoos as safe places for animals, where struggles such as having difficulty finding food and avoiding predators(猛兽) don"t exist. Without such problems, animals in zoos should live to a ripe(成熟的) old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often suffer from poor health. Sometimes, they even become unable to have babies. To learn more about how captivity(圈养) affects elephants, a team of international scientists compared the life spans of female elephants born in zoos with female elephants living outdoors in their native lands. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 African and Asian elephants in zoos across Europe. The scientists compared the life spans of the zoo-born female elephants with the life spans of thousands of wild female elephants in Africa and Asian elephants that work in logging camps(伐木场), over approximately the same time period. The team found that female African elephants born in zoos lived an average of 16.9 years. Their wild counterparts who died of natural causes lived an average of 56 years—more than three times as long. Female Asian elephants followed a similar pattern. In zoos, they lived 18.9 years, while those in the logging camps lived 41.7 years. Scientists don"t yet know why wild elephants seem to get on much better than their zoo-raised counterparts. Georgia Mason, a biologist at the University of Guelph in Canada who led the study, thinks stress and obesity(肥胖症) may be to blame. Zoo elephants don"t get the same kind of exercise they would in the wild, and most are very fat. Social lives of elephants are also much different in zoos than in the wild, where they live in large herds and family groups. The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce(生殖) successfully and maintain healthy populations, that doesn"t appear to be the case with elephants.

单选题A New Book All day long, you are affected by large forces. Genes influence your intelligence and willingness to take risks. Social dynamics unconsciously shape your choices. Instantaneous perceptions set off neutral reactions in your head without you even being aware of them. Over the past few years, scientists have made a series of exciting discoveries about how these deep patterns influence daily life. Nobody has done more to bring these discoveries to public attention than Malcolm Gladwell. Gladwell's new book Outliers seems at first glance to be a description of exceptionally talented individuals. But in fact, it's another book about deep patterns. Exceptionally successful people are not lone pioneers who created their own success, he argues. They are the lucky beneficiaries of social arrangements. Gladwell's noncontroversial claim is that some people have more opportunities than others. Bill Gates was lucky to go to a great private school with its own computer at the dawn of the information revolution. Gladwell's book is being received by reviewers as a call to action for the Obama Age. It could lead policy makers to finally reject policies built on the assumption that people are coldly rational profit-maximizing individuals. It could cause them to focus more on policies that foster relationships, social bonds and cultures of achievement. Yet, I can't help but feel that Gladwell and others who share his emphasis are preoccupied with the coolness of the discoveries. They've lost sight of the point at which the influence of social forces ends and the influence of the self-initiating individual begins. Most successful people begin with two beliefs: the future can be better than the present, and I have the power to make it so. They were often showered by good fortunes, but relied at crucial moments upon achievements of individual will. These people also have an extraordinary ability to consciously focus their attention. Control of attention is the ultimate individual power. People who can do that are not prisoners of the stimuli around them. They can choose from the patterns in the world and lengthen their time horizons. Gladwell's social determinism overlooks the importance of individual character and individual creativity. And it doesn't fully explain the genuine greatness of humanity's talents. As the classical philosophers understood, examples of individual greatness inspire achievement more reliably than any other form of education.
