Global warming lead to Arctic ice layer to start to melt

Scientists worry that the release of methane lead to global warming, exacerbated by global warming and creating a vicious cycle. Historically, the methane has led to the sudden release of a large number of large-scale extinction of species! 

     Scientists found global warming led to the seabed of the Arctic ice began to melt layer, and the melting of the frozen layer is leading to more than 20 times that of carbon dioxide powerful greenhouse gas - methane has been released, will greatly intensify the pace of global warming, which Lead to more methane release, and in the history of the Earth, the sudden release of methane has led to the mass extinction of species in the latest research! 

     The shocking news of 23 was the first to a disclosure by British media. Exclaimed the media, buried in the Arctic a "time bomb methane"! 

     Thaw frozen layers of methane release 

     At present, containing a number of Russian scientists in the Arctic scientific expedition ship is an environmental study, the research vessel ship had been walking along the Russian coast of the northern part of the lap. Scientists involved in this study found that the effects of global warming in the Arctic has exceeded the level of people's imagination. 

     With the Arctic seabed permanently frozen layer of the thaw, millions of tons of methane being released into the atmosphere, as in the greenhouse, carbon dioxide is a devastating methane is 20 times. So scientists are worried that the Arctic seabed methane release will greatly increase this planet has a very serious greenhouse effect.

The mass extinction of species? 

     Scientists believe that methane levels in the atmosphere is essential, because all of a sudden a lot of methane gas release in the history of the earth have been caused by the sudden rise in global temperatures, rapid climate change is even a large-scale extinction of species. 

     In recent days, the scientific expedition on board the researchers to see many methane bubbles continue to follow the "methane passage" out of the Arctic sea. 

     Scientists believe that the discipline of ice on a frozen layer to form a permanent, is to act as the prevention of gas from the sea to escape the "lid" and now, with the thawing of frozen layer, the lid has been unable to cover the gas outside the Harbor Plaza. 

     Global warming vicious cycle 

     Scientists detected in the Siberian continental shelf covers an area of 10,000 miles on the region, the concentration of methane in the atmosphere is very high, sometimes reaching 100 times the normal value. 

     According to the scientists estimated that the Arctic ice under the storage of methane than the world's total coal storage of carbon than. As the Arctic warming faster than the speed of other places, scientists are very worried that the stability of the seabed methane. 

     In view of the methane in the greenhouse area of destructive carbon dioxide is 20 times, scientists worry that the release of methane lead to global warming, exacerbated by global warming, and this process will lead to more methane release, Further aggravate global warming, resulting in a vicious circle. 

     The leadership of Sweden's Arctic expedition of scientists Jane Auer Gustafson has been written into the Arctic this inspection report - "2008 International Studies Siberian continental shelf," will soon by the American Geophysical Association. 

     In recent decades, the Arctic average temperature rise of 4 degrees Celsius, the Arctic ice melting faster in a large number of ice disappear. 


     Methane on Earth 

     Methane is the simplest organic compounds, is a no color, no odor, it is extremely difficult water-soluble flammable gas is lighter than air. Methane and air mixture to form an appropriate proportion, the event will spark an explosion. 

     Plant leaves and produces methane, and the production and sunshine with the temperature increase and enhanced. In addition, the plant produced methane is the decay of plant 1-10-fold. For historical reasons, a large number of methane gathered at the North Pole under the ice, like a lid cover, like methane, its atmosphere is no longer involved in the cycle. 

     With carbon dioxide, from the beginning of the Industrial Revolution, the atmospheric concentration of methane began to increase. Human activities including oil and gas drilling, as well as agriculture, aggravated by methane in the atmosphere of the content. 

     Over the past 10 years, the atmospheric concentration of methane has not increased, some analysts said could be attributed to Russian oil-drilling technology improvements. However, last year, scientists found that the global concentration of methane over the past 10 years the increase for the first time, but this year there are signs of a further increase. 

     The good news is that methane can quickly break down the environment, with an average of 12 years can be broken down End, and the same amount of carbon dioxide need to break 100 years. The bad news is that human beings are not clear under the Arctic ice cap methane storage of the earth will bring. Scientists worry that the cause of global warming will be much higher than the level of expectations.
