A build-up of manmade greenhouse gases in the atmosphere meant a warmer future was now inevitable, WMO Secretary-General Michel Jarraud said in a statement on the sidelines of U.N. climate talks among almost 200 nations in Warsaw.
The WMO, giving a provisional overview, said the first nine months of the year tied with the same period of 2003 as seventh warmest, with average global land and ocean surface temperatures 0.48°C (0.86°F) above the 1961-1990 average.
“This year once again continues the underlying, long-term trend,” towards higher temperatures caused by global warming, Jarraud said. The WMO said it was likely to end among the top 10 warmest years since records began in 1850.
Among extremes have been super typhoon Haiyan, one of the most intense storms in history that smashed into the Philippines last Friday.
