You prolly didn't read the study, which also was covered in the Live Sci which Bummer seems to like..

Global warming may fuel stronger hurricanes whose winds whip up faster, new research suggests. Hurricanes and other tropical cyclones across the globe reach Category 3 wind speeds nearly nine hours earlier than they did 25 years ago, the study found. In the North Atlantic, the storms have shaved almost a day (20 hours) off their spin-up to Category 3, the researchers report. (Category 3 hurricanes have winds between 111 and 129 mph, or 178 and 208 kph.)

"Storms are intensifying at a much more rapid pace than they used to 25 years back," said climatologist Dev Niyogi, a professor at Purdue University in Indiana and senior author of the study.

What Is the Greenhouse Effect?

Left: Naturally occurring greenhouse gases — carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) — normally trap some of the sun’s heat, keeping the planet from freezing. Right: Human activities, such as the burning of fossil fuels, are increasing greenhouse gas levels, leading to an enhanced greenhouse effect. The result is global warming and unprecedented rates of climate change.
