2050年的“天气预报”：伦敦夏天平均气温27度（双语）

　　一项“乐观”的研究指出，如果世界各国采取措施减少碳排放，在2050年前把气温增幅控制在2摄氏度以内，那么到时候各大城市的气温仍会显著上升，部分城市将遭遇剧烈的气候变化影响。具体详情请看2050年的“天气预报”。

　　London could feel as hot as Barcelona by 2050, with Edinburgh's climate more like Paris, Leeds feeling like Melbourne and Cardiff like Montevideo.

　　2050年伦敦将和巴塞罗那一样热，爱丁堡的气候更接近巴黎，利兹气温和墨尔本趋同，加的夫则与蒙得维的亚(乌拉圭首都)类似。

　　That's from a study looking at how a 2C temperature increase could change the world's 520 major cities.

　　一项研究预测了全球气温升高2度对世界520个大城市的影响。以上结果就来自这项研究。

　　And that's not as good as it might sound.

　　结果比听上去还要糟。

　　More than a fifth, including Singapore and Kuala Lumpur, will experience conditions big cities haven't seen before, the Crowther Lab says.

　　克劳瑟实验室称，超五分之一的城市，包括新加坡和吉隆坡，将面临大城市前所未见的气候变化。

　　London could suffer from the type of extreme drought that hit Barcelona in 2008 - when it was forced to import drinking water from France at a cost of £20 million.

　　伦敦将经历2008年巴塞罗那遭遇的极度干旱，当时巴塞罗那被迫耗资2000万英镑(1.7亿元人民币)从法国进口饮用水。

　　The 2C rise by 2050 is comparing the present day to what temperatures were in the "pre-industrial period" - usually considered to be between the years 1850 and 1900 - when fossil-fuel burning hadn't yet changed the climate.

　　到2050年上升2摄氏度是同前工业时代的气温作对比。通常认为1850年到1900年是前工业时代，那时候化石燃料的使用尚未改变气候。

　　fossil-fuel: 化石燃料

　　That temperature increase would result in the average UK temperature during summer's hottest month increasing by about six degrees to 27C.

　　气温升高会导致英国夏日最热月份的平均气温升高6摄氏度，达到27摄氏度。
