WMO: Warmest decade since 1850
30.11.2011 08:02 "Agro Perspectiva" (Kyiv) —
New research from the World Meteorological Organization or WMO shows that 2011 has been the tenth warmest year since 1850.
A report released by the organization on Tuesday added that global temperatures in 2011 have been higher than any other previous year with a La Nina event, an ocean atmosphere phenomenon which has a cooling influence.
A 2.0 degree Centigrade rise in global temperature threshold was set at the World Conference in 2005, beyond which climate change is likely to be unstoppable.
The report says with the increase in greenhouse gases, any rise above this threshold, which is rapidly approaching, could trigger drastic changes.
WMO Secretary-General Michel Jarraud says high temperatures are already affecting water ice levels in the arctic.
«During the La Nina years, temperatures tend to be significantly colder than during normal years. Despite La Nina it was a very warm year to the point that it is the warmest decade on record, the ice in the arctic continues to melt. In 2011 it was not the record but it was the second lowest extent of ice in the arctic,» admits Jarraud.
