The first decade of this century has been, by far, the warmest decade on the instrumental record.
New figures released today in Copenhagen show that - despite 1998 being the warmest individual year - the last ten years have clearly been the warmest period in the 160-year record of global surface temperature, maintained jointly by the Met Office Hadley Centre and the Climatic Research Unit at the University of East Anglia.
These figures highlight that the world continues to see global temperature rise, most of which is due to increasing emissions of greenhouse gases into the atmosphere, and clearly shows that the argument that global warming has stopped is flawed.
Separately, the World Meteorological Organization (WMO) has today revealed that 2009 looks set to become another top-ten warm year according to latest figures, with a provisional warming of 0.44 °C above the long-term average of 14.0 °C.
2009 has been warmer than 2008, owing to the emergence of El Niño conditions in the eastern tropical Pacific Ocean, and is expected to be the fifth-warmest year in the instrumental record that dates back to 1850.
