2013 is seventh hottest year on record

WARSAW - This year is the seventh warmest since records began in 1850 and rising sea levels caused by climate change are aggravating the impact of storms such as Typhoon Haiyan in the Philippines, said the World Meteorological Organisation (WMO).

More greenhouse gases in the atmosphere meant a warmer future, and more extreme weather, was inevitable, WMO Secretary- General Michel Jarraud said in a statement during climate talks among almost 200 nations in Warsaw.

The WMO 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 deg C above the 1961-1990 average.

"This year once again continues the underlying, long-term trend" towards higher temperatures caused by global warming that are causing more heatwaves and downpours, Mr Jarraud said.

The WMO said it was likely to end among the top-10 warmest years since records began in 1850.

Extreme events include super typhoon Haiyan, one of the most intense in history that smashed into the Philippines last Friday, it said. However, the WMO said that it was impossible to blame climate change for individual storms.

"The jury is still out on whether tropical cyclones will become more frequent in the future," Mr Jeremiah Lengoasa, Deputy WMO Secretary-General, told a news conference.

He pointed to wide uncertainties about how they form.
