Number of Powerful Hurricanes Increasing

According to a new study to be published in the jounal of Science, the number of powerful hurricanes in the last 35 years has nearly doubled due to increases in ocean water temperatures. However, the jury is still out on whether or not this warming is due to man. “What we found was rather astonishing,” said Georgia Tech’s Webster. “In the 1970s, there was an average of about 10 Category 4 and 5 hurricanes per year globally. Since 1990, the number of Category 4 and 5 hurricanes has almost doubled, averaging 18 per year globally.” […] “Category 4 and 5 storms are also making up a larger share of the total number of hurricanes,” said Curry. “These hurricanes made up about 20 percent of all hurricanes in the 1970s, but over the past decade they accounted for about 35 percent.”
