Irrespective of the Paris Agreement, scientists conclude that the process of melting permafrost can not be stopped and will reach the polar cities of Russia, Canada and the United States.
According to recent scientific findings published in an article in the journal Nature According to communications, more than 70% of the permafrost structure (permanently frozen soil layer in high latitude regions) will be dedicated to l '. failure and risk of disaster
"Our observations have long convinced me that global warming can not be a product of the imagination of climatologists, but it is very real.The Alaskans, for example, must already manage theirs they will become even more dangerous in the future, "said Vladimir Romanovsky, an employee of the Cryosphere Institute, a subsidiary of the University of Alaska in Fairbanks, Florida.
The defrosting process will cause the decomposition of frozen and accumulated organic matter for millions of years, releasing methane and carbon dioxide into the atmosphere, while natural fires would aggravate global warming
] Climatologists have warned that Arctic warming will result in the disappearance of permafrost areas that appeared during the last glaciation in Siberia, Alaska and the polar regions of Canada .
The melting of this layer of Romanovsky frozen ground would destroy the cities built in the tundra territories in the Russian, Canadian, European and American Arctic
Over the next 30 to 40 years, scientists have estimated that melting permafrost would affect more than half of the Arctic cities of five countries, regardless of what humanity does to combat global warming. About 60 to 80% of residential buildings and about one million Arctic residents will be at risk.
This process will be particularly dangerous for Russia as half of the oil and gas production facilities and pipelines located in the permafrost thaw zone. This could cause enormous damage to Russian companies and destabilize the future situation in Europe and in the world.
The joint work of scientific teams will badist the authorities of the main regions likely to be affected and will prepare for such events, thereby avoiding mbadive deaths and economic collapses.
