(www.neomundo.com.ar) according to a report published by the World Meteorological Organization of the United Nations, global temperatures measured during the year 2011 are currently the tenth record in the Top Ten highest annual.

And also the records of this year are higher than any previous year having log with the event weather “La Niña”, which has an influence towards the cooling.

Another statistic of labour is that statistical history 13 hottest years have occurred in 15 years to come since 1997.

As final registration, extension in square kilometres of ice in the Arctic sea – 2011 – was the second lowest in the register and its volume was also the youngest.

These points are some of the highlights of the annual work coordinated by the WMO on the State of the global climate.

This study was revealed to the public today during a meeting of the International Conference on climate that takes place in Durban, South Africa.

“Our role is to provide scientific expertise to inform those who must make decisions,” said the Secretary General of the WMO Michel Jarraud.

And added: “our science is sound and demonstrates unequivocally that the plant is warming and that this warming is due to human activities”.

Data

.

“The concentrations of GHGs in the atmosphere have reached new highs.” And very quickly levels the science indicates are approaching shall ensure an average increase of the temperature between 2 and 2.4 degrees Celsius in global temperatures average.

This figure of increase could lead to irreversible changes in our Earth, the biosphere and the oceans.

Global climate in 2011 was influenced by the event “La Niña” that was developed in the tropical Pacific in the second half of 2010 and continued until May 2011.

This year was one of the strongest in the last 60 years and its course is closely associated with drought in East Africa, Islands in the central equatorial Pacific and South of United States and the floods in southern and Eastern Africa, Australia and Asia South.

Minimum seasonal Arctic sea ice was achieved on 9 September, and was estimated at 4.33 million square kilometres. It’s a figure that is 35% below the average of frozen sea measured in the period from 1979 to 2000 and only somewhat higher than the 2007 record.
