LNG is liquefied natural gas (the same gas that you'd use in your home heating system)
chilled to -161 °C, which reduces its
volume to 1 / 600th of the
volume of gas, making it economically feasible to transport
over long distances by ship.
And we have had increasing evidence of a growing
volume of releases from the East Siberian Arctic Shelf sea bed, to the methane emitting melt lakes proliferating
over the thawing permafrost, to the
chilling and terrifying methane blow holes discovered this year in Siberia.
