Dalamud's descent clearly triggered a huge upset of aether in the short term. What the above quotes partially reference is that this imbalance was not just short term, but long term or even permanent. That's the Seventh Umbral Calamity.
Do you mean the Eighth Calamity, or that the Seventh Calamity is still happening?
