The high concentration of methane in the atmosphere causes the Arctic ice to melt with greater intensity. This in turn affects an increase in sea levels and threatening the security of coastal areas, similar to the peninsula of Florida, USA. The most unusual thing that the methane released from the ancient repository located in the Arctic, and builds up as usual ice melting due to warming-induced climate including increased volume of methane in the air.
Group of oceanographers from Florida State University found 77 novel points of release of methane in Arctic permafrost containing 150,000 craters. Thus, the northern ice is no longer able to keep methane gas in the ground and freely into the atmosphere, contributing to global warming.
If the process of release of methane will continue to gain momentum, then in 50-100 years, Florida and other low-lying coast, where the sea-level rise will cause flooding of 30cm and erosion on the coast of 300-3000 m deep, will feel the effects of this phenomenon. Damaged property of people and life densely populated coastal communities will be at risk.Source: ecowars.tv
