(Reuters) - A huge storm barrels down on the United States, wreaking havoc with punishing winds, record flooding, heavy snowfall and massive blackouts. Is the main culprit climate change or a freak set of coincidences?
Sandy wiped out homes along the New Jersey shore, submerged parts of New York City, and dumped snow as far south as the Carolinas. At least 50 people were reported killed in the United States, on top of 69 in the Caribbean, while millions of people were left without power.
Some scientists say that the key to Sandy's impact may be an extremely rare clash of weather systems, rather than the warmer temperatures that scientists have identified in other hurricanes and storms.
"It's a hybrid storm, which combines some features of tropical hurricanes with some features of winter storms, that operate on quite different mechanisms," said Kerry Emanuel, a professor of Atmospheric Science at Massachusetts Institute of Technology.
While Emanuel said that there is a clear link between climate change and general trends toward more intense tropical hurricanes, in the case of Sandy more long-term study is required to determine whether climate change played a major role. Read More
