According to the research conducted by scientists, the arctic frozen sea bed situated in north of Siberia is emitting powerful greenhouse gas, methane, raising the risks that could incline the danger level of global warming.

However, it is quite difficult to assert on the fact whether the methane emission is something that has occurred just in the recent times or is it something which has been creeping for many decades, going un-noticed. Scientists are not sure if the gas release issue has suddenly cropped up, leading to a change in the climatic conditions.

The research depicts that the frozen sea is emitting around 8 million tons of methane a year, which is continuously leaking out from the valves of the permafrost under the layers of the ocean in north of Russia.

Further, the experts discovered the intensity with which the methane gas is popping out from the sea bed. The intensity of the seepage of methane is so high that it can decompose the vegetation, in water and air at 5,000 sites. Some places are there, where the intensity of methane has soared up leading to the formation bubbles out of the sea.

The question is still persisting at the base that what caused the methane to pop up with such intense levels, is it global warming which has sparked off the methane or is it the natural factors.

The emission of just a fraction of methane has triggered worst climatic condition.
