Yeah, that and the one in two is "natural" and the one in seven is human-made. It's apparently more likely that a rogue natural black hole will kill us all than we are to accidently make one with a particle accelerator.

They left out super-volcanos.

And I hose don't mean tscientologist "H-Bomb Fotified Thetan Flinging Volcanoes(tm)", either]

I've always been sort of comforted by the notion that whether or not we destroy the Earth for most life, the planet itself goes on. It's wiped clean of life, but life probably rises again and so things go on as they should, maybe with some sentient lifeforms wiser than us.

I'm not so sure I like #2 or #7, they seem a bit more nerve-wracking.

So the poles reverse...I don't see how that, alone, wipes life off the planet. It's happened regularly in the (distant) past.

I can't believe they failed to mention insufficient telephone handset sanitation workers.

Pat York, I think with a pole reversal you get instantaneous change in the stresses on ferrous material throughout the earth's crust, and this results in earthquakes all over the world.

Or something like that.

Like the pole reversal. Last time it happened, it disrupted the Van Allen radiation belt which mutated apes into humans.

i get it now, i was thinking "rogue black hole" like in that david brin story. like i thought the particle accelerator mishap wasn't really about creating a black hole, but a more stable form of matter. kind of like ice-9, but for um, matter.

I do believe I read somewhere that the ozone hole may travel along with a shifting pole ... suncreen, anyone?

There are fluctuating "ozone depletion areas" all over the place these days... don't wait for the pole to shift to wear sunscreen.

And in a few more years, we'll all be taking supplemental vitamin D...

Ice age. Don't forget the last ice ended only about 12,500 years ago. That's a blink in geologic time and a nano in astronomical time.

no matter what we do an asteroid is going to crash on our planet but in a few million years
I think global warming will end human life

do you think the world is going to end

i think the world will end by the oracles predictions
