Permafrost a probable source of greenhouse gases, scientists claim
Scientists in Tomsk, Russia, believe that the high degree of underwater permafrost degradation in the Arctic may lead to disastrous global warming, the Arctic-Info news agency reports.
Experts found that the Siberian Arctic shelf is a major source of greenhouse gases. For example, the eastern Arctic emits as much methane as all of the world's oceans.
Researchers have also discovered over 500 abnormal methane-emitting areas which, in turn, can seriously affect the global climate.
Scientists have used their research results to compile four climate change scenarios. According to the worst-case scenario, about three to five percent of estimated hydrate reserves could spew into the atmosphere over the next decade.
