[Tilted Irish Kilt]

JimSEA :" "Also contributing to climatic/extinction effects are the abundance of LIP-produced pyroclastic material and volatile fluxes
that reach the stratosphere, and in particular the role of super-eruptions."

Don't forget gases flowing and erupting naturally from the Russian permafrost .
How does one control those ?

If it’s basaltic lava flows as was the case with the Russian Traps, nothing would work.
