New study warns of methane escaping from the sea floor due to degradation of submarine permafrost.
New expedition in Laptev Sea suggests increase in the rate of underwater permafrost degradation.
Warning of methane blasts in Kara Sea adjacent to Yamal craters caused by gas eruptions associated with melting permafrost due to global warming.
More craters expected to form due to such eruptions as permafrost melts - and they ARE caused by global warming releasing methane gas.
Subsea permafrost thaws faster than previously thought, Russian scientists say.
Man ‘caused some of the tundra blasts forming the large holes’, says leading scientist in surprising new theory.
200 metres wide thermocirque seen weeks after scientists find funnel in the Yamal peninsula, caused by build up of methane.
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.
