This year is the seventh warmest since records began in 1850 with a trend to weather extremes and the impact of storms such as Typhoon Haiyan in the Philippines aggravated by rising sea levels, the World Meteorological Organization (WMO) said on Wednesday.

A build-up of man-made 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, Mr. 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.

President Benigno Aquino said local officials had overstated the loss of life, which was closer to 2,000 or 2,500 than the 10,000 previously estimated. His comments, however, drew skepticism from some aid workers.

Other extremes this year have included record heat waves in Australia and floods from Sudan to Europe, the WMO said. Japan had its warmest summer on record.
