Publishing its annual climate report, the UN's World Meteorological Organisation said that last year continued a long-term warming trend, with the hottest year ever in Australia and floods, droughts and extreme weather elsewhere around the world.

Michel Jarraud, the WMO's secretary-general, also said there had been no 'pause' in global warming, as has been alleged by climate change sceptics.  “There is no standstill in global warming,” Jarraud said.

2001-2010 was the warmest decade on record, the WMO noted, and added that the last three decades had been warmer than the previous one.

The WMO reiterated its earlier finding that 2013 was the sixth warmest on record, with temperatures 0.5C above the long-term average (1961-1990).  The southern hemisphere was particularly warm, its report said, with Argentina experiencing its second warmest year on record and New Zealand its third warmest.

Arctic sea ice in 2013 did not reach the record lows seen in 2012 for minimum extent in the summer, but was at the sixth lowest on record.  The WMO noted all seven of the lowest Arctic sea-ice extents took place in the past seven years, starting with 2007, which scientists were "stunned" by at the time.
