Global Warming Causing Hurricanes?

From CNN:

"Over the past few years, we've seen an increasing trend toward greater activity in the Atlantic Basin and increased strength in storms," said Marshall Shepherd, a research meteorologist at NASA's Goddard Space Flight Center. "[That] has been leading us to believe that we are going to start seeing more intense hurricanes. That may be bearing itself out right now."

A combination of natural cycles and warming ocean temperatures from global warming may be fueling the destructive storms. Scientists like Shepherd employ an array of satellites, aircraft and computer models to answer those questions in their mission to comprehend the Earth's climate.
