When did you last see a hurricane morph into a storm with a diameter of 900 miles? When did you see a tidal surge roll up the southern tip of Manhattan Island for 30 blocks? When did you see 8 million Americans out of electricity from the same storm?
The answer to these questions is "never." But relax, because you have probably not seen the last example of this phenomenon.
Climatologists have argued that global warming has raised ocean temperatures, especially in the gulf stream, providing more energy fuel for hurricanes. They have argued that the sea level of the Atlantic Ocean has risen nearly one foot over the past 100 years, also due to global warming. They have argued that "normal" weather patterns give way to less predictable weather patterns as arctic ice melts and wind patterns respond to different temperature patterns between various regions.
If you don't want to know the obvious, that's on you. Slightly over half of Americans are thinking that global warming has something to do with Sandy. The rest of us think that we have seen something weird and outside the experience of our entire lives, but there is probably some other explanation. Problem is, those denialists simply have no idea what the other explanation is, and really are not trying to develop such an explanation.
We had a record breaking drought, a record breaking derecho thunder storm event, and finally a record breaking hurricane/nor'easter event, all in 2012. Some people just are not curious, I guess. :)
