It was a dying on a scale never seen before or since on Earth. The slaughter was everywhere; the fertile ocean and balmy supercontinent Pangea were
transformed into killing fields, littered with the bodies of ancient animals. By the time the dust had settled on the Permian-Triassic mass extinction
250 million years ago, 90 percent of life on the planet had been snuffed out.
Now a new theory suggests the catastrophe was set in motion 15 million years earlier, deep in the Earth. On the edge of the molten outer core, a plume
of super-hot material began rising through the mantle, upsetting convection in the core and throwing the planet's magnetic field into disarray.

The scary thing to me is that this seems to be in the process of happening again fairly soon...
