Last year was the warmest in the history of the Arctic and Siberia

The average temperature in the Arctic and Siberia in the last year reached the highest value ever recorded, and in the northern hemisphere in 2011 was among the ten warmest, according Roshydromet.

"In 2011, once again, as in 2010, the largest annual air temperature anomalies were formed in the Arctic — to 5 degrees above normal and more, but this time not in the Canadian, and Russian. In the north of Scandinavia and Canada, European Russia and the Urals, in most of Siberia, and in some areas of the U.S. and France, as well as parts of the Pacific and Atlantic Oceans anomalies exceeding 2 degrees, "- said in a statement.

In late November last year, the World Meteorological Organization (WMO), the report on the state of climate change, said the figures in 2011 put it at number 10 in the "rating" of the warmest years, with the first 13 places of the rankings to the period from 1997 to 2011 years.

Previous, 2010 was a record-warm the planet, sharing first place with 2005. According to the Hydromet, the average temperature in the northern hemisphere in 2011, entered the top ten of the highest values for the whole period of regular meteorological observations.

"However, it is much, by 0.14 degrees, gives absolute record, set in the past (2010 — Ed.) Year. Has been suggested that a decrease in the average annual temperature is caused by the existence of La Niña in the beginning and the end of 2011, which forms abnormally cold water on the surface of the Pacific Ocean, which has a global impact on the weather, "- said the weather service.

According to it, any of the months of 2011, the average temperature has not reached record levels, and not even among the top three most vysokoranzhirovannyh, while in 2010 five months set an absolute record values (May-August and November).

Temperature below normal was observed in the east Pacific, Southeast Asia and eastern India — these regions are particularly affected by La Niña, and northern Kazakhstan and parts of Greece, Turkey and the North Caucasus, the report says.

In most regions of the Northern Hemisphere observed usual amount of precipitation, but in India and South-East Asian summer monsoon in 2010 was longer and stronger than the average.

"Precipitation totals were 120-180% of normal. Abundance of record rains led to the strongest in 50 years floods and literally paralyzed by many countries. Central China after heavy winter drought came torrential rains caused massive flooding," — said in a statement.

The excess of the annual amount of precipitation over the norm was observed in the northern and north-eastern states of the USA, Scandinavia, parts of the Middle East, Kazakhstan, Central Asia and in the western part of the African Mediterranean.

In this vast area of Africa, the Middle East, Central Asia, China, Mongolia, southern United States and northern Mexico, a number of European countries — France, Italy, the Balkan countries — had a deficit of precipitation.

"Europe suffered the strongest spring drought, which in England rated as the driest in the last 100 years. Drought and heat in the southern U.S. have led to numerous fires. Area covered by them, is classified as the second largest in the history of the region," — noted meteorologists .
