So the latest news on the reactor situation in Japan seems to be dire. All workers have now left the control room due to rising radiation levels.

They weren't able to cool them down enough while they were there, what the fuck is going to happen now that the technicians are gone?

If 6 reactors, not to mention a cooling pond or 3 maybe, all meltdown, just how bad would that be on a worldwide level.

I'm looking for serious answers here, because it seems to me like it is a very real possibility at this point in time.

Scientist types are my first choice for answers, but anyone is also welcome to throw in your two cents too.
