7. Until then, the natural forces will offset the expected warming caused by human activities, such as the burning of fossil fuels, which releases the greenhouse gas carbon dioxide.To check their models, the scientists used a series of \"hindcasts\" - forecasts that look back in time - going back to 1982, and compared what their models predicted with what actually occurred. 30\'
直到那时,自然的降解力尚可以抵消像燃烧化石燃料造成温室气体二氧化碳那样的人类活动所造成的气候变暖。为检验他们的模型,这些科学家使用了“向后预测”----对过去的历史进行预测,然后回到1982年,将模型推测的结果和真实历史进行比较。
12. At its height from 1906 to 1910, estimated warming from soot on Arctic snow was eight times that of the pre-industrial era, the researchers said. 10\'
3. To make this kind of prediction, researchers at Britain\'s Met Office - which deals with meteorology - made a computer model that takes into account such natural
phenomena as the El Nino pattern in the Pacific Ocean and other fluctuations in ocean circulation and heat content. 20\'

4. A forecast of the next decade is particularly useful, because climate could be dominated over this period by these natural changes, rather than human-caused global warming, study author Douglas Smith said by telephone. 15\'

研究学者 Douglas Smith 通过电话说:天气预报在未来的十年特别有用,因为那个时候的气候主要由自然的变化所统治,而不是人类因素导致的全球变暖。
1. Global warming is forecast to set in with a vengeance after 2009, with at least half of the five following years expected to be hotter than 1998, the warmest year on record, scientists reported on Thursday. 15\'
科学家在星期四报道,全球气候变暖预告在2009年后将实施报复,使接下来的五年至少一半时间比历史记录最高的1998年还热.
2. Climate experts have long predicted a general warming trend over the 21st century spurred by the greenhouse effect, but this new study gets more specific about what is likely to happen in the decade that started in 2005. 15\'
气候专家作了长期预测,21世纪大体的气候趋势将受温室效应刺激,但是这项新的研究对自2005年以后的十年将发生什么有更清楚的了解.
3. To make this kind of prediction, researchers at Britain\'s Met Office - which deals with meteorology - made a computer model that takes into account such natural phenomena as the El Nino pattern in the Pacific Ocean and other fluctuations in ocean circulation and heat content. 20\'
为了做这方面的预测,英国的MET要作室研究者作了一个电脑模型,这种电脑模型能估算诸如太平洋厄尔尼洛现象和其他像海洋循环和热流波动的自然现象.
