The next major weather event will be a cloud passing through the night unnoticed.

Or a firestorm.

Don’t count out an earthquake.

Or a solar flair that shuts down the U.S. electrical system.

Or an asteroid strike in the Pacific that causes a massive tsunami.

Or the sun maturing as a star, expanding to the point that it consumes the Earth.

Otherwise, with Ken’s adept hand; it should be a good harvest.
