The big worry is if Betelgeuse does explode and we finally see the supernova explosion, it could be accompanied by a HUGE burst of potentially deadly radiation--especially gamma rays. And that right there will essentially eliminate all life on Earth not living deep underground, effectively resetting the life cycle of evolution (one wonders if the massive die-off in life around 250 million years ago was caused by a nearby star exploding and showering the Earth's surface with deadly gamma rays).

Global warming will kill us all before then, Al Gore told me so...
