Our Planet faces Meltdom
Global warming is heating the planet twice as quickly as previously feared. Temperatures could soar by nearly 6chkenºC this century-faster than at any time in the past 10,000 years, warns a UN report relead recently. In the past 100 years the temperature ro by only 0.6ºebitdaC. But the last decade of the 20教师资格证培训机构th century was the warmest on record. Talks to cut emissions by five per cent collapd in The Hague veral months ago. The report warns that a temperature ri if up to 5.8北京留学服务中心>2013奥斯卡ºC, with the warming of the oceans and melting of polar icecaps, will force a levels to ri by as much as 3ft, making tens of millions of people in Bangladesh and Egypt homeless. Parts of lowland Britain are also at risk. Scientists believe the predicted ri, which will bring storms, floods and droughts will be partly due to a reduction in air pollution. The report was issued at a meeting in Shanghai attended by experts from 99 countries. A pollution clean up will be partly to blame for such a temperature ri. A reduction in emission of sulphur dioxide, which caus acid rain, has incread the impact of greenhou gas. The gas trap the sun’s heat whereas sulphur dioxide cools the atmosphere. The UN’s International Panel on Climate Change call
ed on governments to step up efforts to curb global warming by reducing emissions of greenhou gas such as carbon dioxide which are produced by burning fossil fuels. British scientists Professor Sir John Houghton said: “The six degrees depends on just how much fossil fuel we burn this next century. If we burn less, then the increa will be less.” Roger Higman, spokesman for environment campaigners Friends of the Earth, said the report was “terrifying”.
anything合肥培训地球面临冰消雪融
老外教英语全球变暖有人们以前担心的两倍那么快。近来联合国发表报告警告说，21世纪地球气温可能上升近6摄氏度——比过去1万年的任何时候都要迅速。在过去100年里，地球的气温上升了0.6摄氏度。但20世纪的最后10年里，气温达到了最高记录。数个月前在海牙进行的减少5%的温室气体排放的谈判失败了。报道警告说，若地球气温升高5.8摄氏度，随着海洋变暖和极地冰帽融化，海平面将升高3英尺，几千万孟加拉人和埃及人将无家可归，部分英国低地也面临着同样的危险。科学家们相信其预言的升温将带来风暴、洪水和旱灾，部分原因将是空气污染减少。该报告是由在上海举行的有99国专家参加的一次会议上发布的。filckr
这种升温将部分地归咎于污染的消除。引起酸雨的二氧化硫气体排放减少，温室气体的影响随之扩大。这些气体留住‘阳光中的热量，而二氧化硫使空气冷却。联合国气候变化国际专门小组呼吁各国政府进一步努力，减少排放矿物燃料燃烧产生的诸如二氧化碳等温室气体，以制止全球变暖。英国科学家约翰子侄·霍顿爵士教授说：“是否升高6摄氏度取决于21世纪燃烧多少矿物燃料。燃烧得少，气温升高也少。罗杰·希格曼是环保运动“地球之友”的发言人，他说联合国的报告“令人恐惧”。
