It's the end of the world as we know it

I'm trying to think of realistic extinction-event scenarios that don't involve nuclear bombs or things crashing down from outer space, but would doom humanity in about the same time frame (wiped out within a generation, or even quicker.)

When I say "realistic" I mean more "doomed by widespread wheat blight" or "bio-engineered plague" and less "aliens attack" or "robot overlords."
While I'm interested in things that would push humanity into extinction within a generation, I'm also interested in more dramatic events, ecological disasters, etc that could quickly snowball into bringing about the end of the human race within days, weeks, or months.
I've googled this a fair amount so I'm already familiar with the obvious ones (magnetic pole shift, gamma radiation, stray comets, global warming, etc) but I'm looking for the potentialities that we don't often think about. Science-based if possible, please.
