A newly released analysis by the World Meteorological Organization shows that this decade is very likely the warmest in the modern record, and 2009 is on track to be the fifth warmest year ever recorded.

The decade of the 2000s is very likely the warmest decade in the modern record, dating back 150 years, according to a provisional summary of climate conditions near the end of 2009, the organization said.

The period from 2000 through 2009 has been “warmer than the 1990s, which were warmer than the 1980s and so on,” said Michel Jarraud, the secretary general of the international weather agency, speaking at a news conference at the climate talks in Copenhagen.

The international assessment largely meshes with an interim analysis by the National Climatic Data Center and NASA in the United States, both of which independently estimate global and regional temperature and other weather trends.

Mr. Jarraud also said that 2009, with some uncertainty because several weeks remain, appears to be the fifth warmest year on record.

Climate Progress has more on this announcement, which is based on multiple sources of data: World Meteorological Organization and NOAA both report: 2000-2009 is the hottest decade on record.

Here’s the announcement at the WMO site: 2000–2009, THE WARMEST DECADE.

The report includes this disturbing graph, produced from three Global datasets: NOAA (NCDC Dataset) , NASA (GISS dataset) and combined Hadley Center and Climate Research Unit of the University of East Anglia (UK) (HadCRUT3 dataset).
