In BR, I realized that the proper interpretation of the occurrence of severe climatic warming (SCW) or volcanic activity (VA) was through the Inclusive "Or", which says and/or. But that would mean one of them must occur. /A-->B. However, in reading the sentence it's clear that neither of those events must happen. After thinking about it for a few minutes, I realized that the presence of "could" alters each of those ideas because we're talking about what's possible and not what occurred.
Temporary melting = TM
Could = c
TM --> SCWc or VAc
If TM, then either could happen, but neither must happen.

Good catch. "Could" changes the game. Great example of how I'm always talking about grammar!
We talked about this in depth in a BR group once. That could really shakes things up! It really changes the conditional relationship.
Glad that you were able to break this down solo, as we spent a loooong time discussing it!
