no official Category 6 for hurricanes, but scientists say they're
pondering whether there should be as evidence mounts that hurricanes around
the world have sharply worsened over the past 30 years -- and all but a

fingerprints of man-made global warming. In fact, say scientists, there have
already been hurricanes strong enough to qualify as Category 6s. They'd
define those as having sustained winds over 175 or 180 mph.
 2006 hurricane forecast: 8-10 storms --National Hurricane Center says

storms slammed into the United States, the U.S. government's top
climate agency said on Monday.
