Hurricane Sandy would not have happened without global warming. Why? Normally, hurricanes do not travel this far north this late in the season. Sandy was aided by unusually warm ocean temperatures. These temperature anomalies have become more frequent in recent years. These anomalies are the signature of climate change. Was climate change the only reason for Sandy's ferocity? No, but the fingerprint is clear.
It's also clear that Sandy will not be the last "Superstorm".
