More questions need to be asked
Before running off for easy politically motivated answers, it seems like quite a number of questions need to be answered. I looked at the NOAA precipitation data, and amount of rainfall on the NYC during Sandy's landfall was miniscule. Likewise the persistent wind speed was very low. It was hardly a "hurricane" at all and the effect more like a tsunami. Most of the damage was caused by the "storm surge" which was mentioned but not emphasized pre-landing. I have read some of the explanations of the surge, like the low pressure, but have not heard of a comprehensive model of why this storm produced a record surge. Also, why is it taking so long for the water to drain now that the storm is over? Surely, you're not claiming that the earth's oceans rose 13 ft in one day, and only on one side of the Atlantic Ocean due to icebergs melting? Question, question, question.
