early atmosphere before the appearance of oxygen.

And finally, what about Mark's questions (# 3) and other factors not discussed here — do all these effects re Arctic ice lead scientists to believe there is a greater and / or
earlier chance (assuming we continue increasing our GHG emissions — business as usual) of melting hydrates and permafrost releasing vast stores of methane into the
atmosphere than scientists believed
before the study, or is the assessment of this about the same, or scientists are not sure if this study indicates a greater / lesser / same chance of this?

early 1930s, long
before the major emissions.
