The following is a good argument about Global Warming. I vote for column "A.” It's all about risk analysis. Do nuclear reactors have redundant systems because a meltdown is likely to happen? No, because meltdown is an event we don’t want to ever happen.
I’m a programmer, and I work for a manufacturing plant that runs 7 days a week, 24 hours a day. Having computer systems that do not go down is expensive, but less expensive then having downtime in the manufacturing plant.
If an event is possible, it does not matter as much how possible the event is, if you do not want the event to ever happen.
