Coastal Arctic Siberia that has been frozen for tens of thousands of years now release stored carbon into the air. The reason is the increase in world temperature which makes coastal melt. Thus the conclusion of a study published on Wednesday (30/8).
Carbon, the source of warming the Earth, is trapped along the 7000 km northeast coast of Siberia since the last Ice Age. However, atmospheric warming and coastal erosion tore permafrost and releasing about 40 million tons of carbon per year into the air. This figure is 10 times higher than previously estimated, according to a study in the journal "Nature".
Approximately two-thirds of the carbon released into the atmosphere as carbon dioxide and the rest trapped in the upper ocean sediments.
Approximately half of the total amount of carbon trapped in the soil stuck in the Arctic. Meanwhile, according to a study led by researchers at Stockholm University ole, the region is experiencing climatic warming-scale two times faster than the world average.
Earlier this week, U.S. scientists has said that sea ice in the Arctic Ocean has melted to the least amount.
The area examined in the study "Nature", named Yedoma, twice the size of Sweden but very rarely studied because it was so difficult to reach.
These findings highlight the vicious cycle of climate change.
Warming Earth's temperature caused by human burning of fossil fuels and then release that stored carbon stocks in permafrost since the last Ice Age or Pleistocene. The gas is released into the air and then add awesome effects of global warming, causing more carbon is released into the air, and so continue to the next.
"Collapse and Pleistocene coastal erosion and sea floor deposits could accelerate climate warming impact on the Arctic," the study warns.
Leakage Yedoma atmosphere equal to the annual emissions of five million cars, with an average of five tons of carbon emissions per year from vehicle in the United States.
In a separate study also appearing in Nature, researchers in the United Kingdom, the Netherlands, and the United States used a computer model to calculate the possibility of 4 tons of methane stored beneath the Antarctic ice sheet.
Methane store the sun's heat 25 times more than carbon dioxide.
Before freezing, the area is filled with the remains of organic sediments are then trapped in the ice-covered.
The researchers stated, "Our computer models show that in millions of years, microbes may convert the carbon into methane gas," so then could accelerate climate warming when the ice is melting.
The breakup of the ice sheet in Antarctica is considered as the worst case scenario of climate experts. Some studies even mentions that the ice sheet is actually growing thicker due to increases in snowfall locally.
