        据世界气象组织称， 2015 年全球温度与过去一年相比普遍高出许多， 2015 年很可能成为有记录以来最热的一年。以下是 Roger Harrabin 的报道。
        The WMO says this five-year period has brought record heat to Asia, Europe, South America and Oceania and North America. This latest October was exceptionally warm.
        The report says 2015 is likely to claim the title of the hottest year recorded, with annual surface temperatures partly fuelled by greenhouse gases and partly by the disruptive current El Nino.
        Greenhouse gas concentrations in the atmosphere reached new highs. And in the northern hemisphere's spring, carbon dioxide levels crossed the threshold of 400 parts per million for the first time.
        The report says more than half of the 79 studies published by the bulletin of the American Meteorological Society in the past five years found that man-made climate change had contributed to extreme weather events over the period.
