If it’s not going to be burning sulfur that rids us of NYC and Washington DC, earthquakes would be a satisfactory Plan B.
Even better would be if they repented like Ninevah but I’m not holding my breath.
Maybe not burning sulfur...
But how about Sulfix and/or Carbfix, which interestingly are being done on the Reykjanes Peninsula in Iceland.
Apparently anthropogenic earthquakes are indeed a thing.
Amen
