ABC’s Last Days on Earth

ABC’s Last Days on Earth, which aired last night as a special edition of 20/20, galloped through seven scenarios for the end of the world, aided by Al Gore and a gaggle of prominent scientists (including the ebullient American Museum of Natural History astrophysicist Neil deGrasse Tyson), and punctuated with earnest vox poppery and some rather stilted, angular commentary from Stephen Hawking.


And according to ABC, the nominees for the most likely end-of-world scenario are:
A gamma ray burst or black hole;
Artificial Intelligence on the loose;
A supervolcano;
The Earth getting hit by an asteroid;
Nuclear annihilation;
A natural or bioterrorist pandemic; and
Global warming, also known as that thing Al Gore’s always talking about.
