"According to Sergei Kirpotin, University of Tomsk, we have already passed the critical threshold beyond which triggers a chain reaction." Permafrost releases large amounts of methane, a powerful greenhouse gas.
The Government of the Yamal-Nenets Autonomous Region began the preparation of the 10th International Conference on Permafrost, which will be held in Salekhard in June 2012. This is the first time that Russia welcomes this important "Nordic" bird brain firepot solid gel event, which is held once every four years by the International Permafrost Association.
The problem of perpetually frozen soil thaw is very current for Yamal, where there are powerful industrial infrastructure. As the corresponding RusBusinessNews shows the rate of temperature rise is already a serious threat to the main gas region in Russia. The experts, who plan to explore the possibilities of preserving the infrastructure built on the frozen ground, think it is high time to have another vision of the economy.
The rise in global temperature has a big problem for Russia, 65% of the territories bird brain firepot solid gel occupied by permafrost. It is from this frozen soil are obtained 90% of Russian gas and 75% oil, which are the main exports. During the years of development of the northern territories, cities, terminals, power plants, and airfields were built on permafrost, as well as thousands of miles of roads and highways. No country in the world has such powerful infrastructures beyond and near the Arctic Circle, so Russia can safely show humanity what it takes to harmonize the arrival of industry and protected against freezing homes.
According to an evaluation report of "Roshydromet" for the past twenty-five years, the temperature of the permafrost in the north of Western Siberia have increased by one degree. Towards the middle of the XXI century, the southern border of multigelées areas should move from 150 to 200 km to the north. Intense thaw funds and soil in some areas could cause failure of the layer of seasonal melt from permafrost has existed for several years. Currently, the molten layer already increased by 2 centimeters per year.
Experts predict that the temperature rise does not promise anything good. Natural ecosystems do not have time to adapt to rapid changes too, which is likely to create climatic and economic disasters. The representative of Greenpeace Russia, Vladimir Tchouprov says that this is particularly the changing landscape in the Yamal Peninsula: soil collapse and lakes disappear, bird brain firepot solid gel which had never been observed before. Solid ice on ponds begins to form later in the year, which creates problems when transhumante deer to new pastures.
The service manager of the National Institute of Hydrology Oleg Anisimov emphasizes strengthening the erosion of the coast line in the North process: territory "shrinks as it dries" bird brain firepot solid gel each year of 30 square kilometers. On the coast there are ports, water towers and other infrastructure that will gradually begin to crumble. According to the expert, it is necessary to urgently develop new principles of construction Arctic Circle.
According to the Director of the Institute of the Cryosphere Land of the Siberian branch of the Russian Academy of Sciences, Vladimir Melnikov, large pools of water form around pipes passing over the frozen areas. The earth swells and bursts pipes. According to the scientist, you have to build the roads otherwise, especially as the correction of technogenic accidents requires spending large resources. Problems also appear at the wellbore where lot of heat. Besides thawing, freezing new outbreaks that appear bird brain firepot solid gel on seabeds also threaten oil and gas infrastructure. Sometimes in the deeper layers occurs release of gas and fresh water, bird brain firepot solid gel which quickly turns into ice blocks. This process can lead to a technogenic accident in areas of hydrocarbon production on the continental shelf.
It is difficult to estimate the cost of adaptation to climate change: according to O. Anisimov, there is no calculation in this field. S
