> close to the baseline More like don't do one of these on accident... :-) "One of the major questions is whether the Siberian Traps eruptions were directly responsible for the Permian–Triassic mass extinction 250 million years ago. A recent hypothesis put forward is that the volcanism triggered the growth of Methanosarcina, a microbe that spewed enormous amounts of methane... altering the Earth's carbon cycle. This extinction event, also called the Great Dying, affected all life on Earth, and is estimated to have killed about 95% of all species living at the time" https://en.wikipedia.org/wiki/Siberian_Traps https://en.wikipedia.org/wiki/Siberian_Traps
