An Eschatological Taxonomy

This guy is great. I didn't read all of his stuff yet, but anyone who puts this together is a superstar.
Examples below, but follow the link to see the whole thing- too cool to miss.

"Eschatology: (noun) The study of the end of the world.
Taxonomy: (noun) A classification in a hierarchical system.


Class: 0
Regional Catastrophe (examples: moderate-case global warming, minor asteroid impact, local thermonuclear war)
Effect: Global civilization not eliminated, but regional civilizations effectively destroyed; millions to hundreds of millions dead, but large parts of humankind retain current social and technological conditions. Chance of humankind recovery: excellent. Species local to the catastrophe likely die off, and post-catastrophe effects (refugees, fallout, etc.) may kill more. Chance of ecosystem recovery: excellent.

Class: 1
Human Die-Back (examples: extreme-case global warming, moderate asteroid impact, global thermonuclear war)
Effect: Global civilization set back to pre- or low-industrial conditions; several billion or more dead, but human species as a whole survives, in pockets of varying technological and social conditions. Chance of humankind recovery: moderate. Most non-human species on brink of extinction die off, but most other plant and animal species remain and, eventually, flourish. Chance of ecosystem recovery: excellent. "
