Has there ever been a known instance in the history of the Earth where it has been capable of doing this? I thought the only way that an ELE is likely to happen is either man made (ie nuclear war), meteor or severe climate change.

My money is on self annihilation before we even get a chance to destroy the climate to the point of not being able to sustain human life.
