Man ‘caused some of the tundra blasts forming the large holes’, says leading scientist in surprising new theory.
Pipes are built over bulging and unstable Arctic pingos prone to violent eruptions caused by 'thawing methane gas', as seen twice on the Yamal peninsula this year.
High levels of ‘fire ice’ trapped in permafrost may turn Russia into a global leader of new gas sources.
Warning of methane blasts in Kara Sea adjacent to Yamal craters caused by gas eruptions associated with melting permafrost due to global warming.
Dissecting them like surgical abscesses to release the gas seen as one solution to avoid future eruptions.
More craters expected to form due to such eruptions as permafrost melts - and they ARE caused by global warming releasing methane gas.
Giant holes created when pingos erupted after filling with gas.
