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\'
5. In research published in the journal Science, Smith and his colleagues predicted that the next three or four years would show little warming despite an overall forecast that saw warming over the decade. 15\'
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\'
为做此种预测，在英国米特研究所（研究气象学）的研究者们制作了一个计算机模型，将与太平洋上的厄尔尼诺现象和其他海洋循环的波动和热变化类似的自然现象都计算其中。
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\'
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(补充说明1998年), scientists reported on Thursday. 15\'

科学家们在星期二的报告预测：2009年后，全球变暖将会加倍上升，在未来的五年内至少比1998年热一半，创下历史性最热的记录。
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\'
到那时，自然力就会抵消掉人类活动（例如燃烧化石燃料，这将释放出温室气体二氧化碳）造成的预期的变暖。为检测他们的模型，科学家们用了一系列的追算法（也就是对过去的时间进行预测），回溯到1982年，然后比较他们的模型预测的结果与真实发生的情况。
10. In another climate change article in the online journal Science Express, U.S. researchers reported that soot from industry and forest fires had a dramatic impact on the Arctic climate, starting around the time of the Industrial Revolution. Industrial pollution brought a seven-fold increase in soot - also known as black carbon - in Arctic snow during the late 19th and early 20th centuries, scientists at the Desert Research Institute found. 35\'
在线杂志科技快讯中的另一个关于气候改变的文章中，美国研究院报道说从工业革命开始来自工业和森林火灾的煤烟对美国的天气有巨大影响。沙漠研究协会的科学家发现从19世纪后期到20世纪，工业污染产生的煤烟在北极圈的雪上增长了七倍
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，自然力量将会弥补人类活动造成的升温的影响，例如燃烧化石燃料，这些燃料将释放温室气体二氧化碳。为了证明他们的模型的准确性，
科学家使用了一系列的方法模拟过去的时代重返1982年，比较他们的模型预测到的和当时的事实
