What Role Did Climate Change Play in Superstorm Sandy?

Superstorm Sandy, a “perfect storm” that was caused by an unusual combination of seasonal weather phenomena converging above the Northeast, has stirred some conversation in the media about whether the storm was caused, or made worse, by climate change.
Scientists have long warned about the risk of a deadly hurricane over the Tri-State area, which would suggest Sandy could be an expected weather event. But recent studies, including a report co-authored by MIT climate scientist Kerry Emanuel in February 2012, note that climate change could combine with the  effects of storm surge to cause 100-year-flooding to occur every two decades in New York, suggesting that an event like Sandy may be more than just a long-expected storm.
