I wonder what they mean when they say "most life". The asteroid 65m years
ago certainly didn't kill most life.
It's large and complex organism that are most sensitive to such calamities,
but fortunately those make up only a small portion (albeit the loudest one)
of life on Earth.
The asteroid that "killed off the dinosaurs" seems to have done for
anything bigger than a rabbit, and somethig of that size would
certainly kill off every last human being within a few years of
impact. On the good side, it would put an end to global warming.
