2013 recorded among top ten warmest yearsListen /
The year 2013 was among the top ten warmest years since modern records began in 1850, according to the World Meteorological Organization (WMO).
The agency says the warmest years on record are 2010 and 2005, with global temperatures about 0.55 °C above the long term average, followed by 1998, which also had an exceptionally strong El Niño event.
WMO points out that surface temperature is the most familiar and consistently measured weather and climate variables and has direct connection to long term climate change.
To find out more about this, UN Radio's Patrick Maigua spoke to WMO Secretary-General Michel Jarraud.
