The same question was being posed at Oil Drum.
I try to stay away from Oil Drum, cuz the prevalence of ‘government education’ is so high and the comments are so inane.
Methane as a solute in salt water is only gonna be about 20 ppm, and it DOES NOT displace dissolved O2 in the water. A modicum of understanding of gas laws would tell you that.
Plus the article calls methane a major component of ‘natural gas’, and also calls it a “dangerous gas”. GEESH, methane *IS* natural gas, not a major component of it (except for the PPB odorants) and TELL ME WHY methane is a “dangerous gas”.
And the guy was reporting from Montana.
