Understanding climate change — key message 1

SOER 2010 Message (Deprecated) Published 28 Nov 2010
Global mean temperature in 2009 was 0.7-0.8 °C higher than in pre-industrial times and the decade 2000-2009 was the warmest on record. The Intergovernmental Panel on Climate Change (IPCC) concluded in 2007 that most of the global warming since the middle of the 20th century is very likely to have been due to human influences.
