Deadly tropical storms and hurricanes seem like they've been on the increase...or have they? Hurricanes cost billions of dollars of damage and can cause thousands of deaths each year, so their frequency and intensity does warrant some careful consideration. To make an informed opinion about climate change and its impact on hurricanes, it is helpful to examine the historical statistics. Since the year 2000, it seems that tropical storms and hurricanes are occurring more frequently, and with more intensity. Are hurricane seasons getting progressively worse? There are many differing opinions within the scientific community. To form your own opinion, its helpful to review the number and types of storms weve experienced in this decade. The first year of the new millennium saw a total of 4 tropical depressions, 7 tropical storms, and 8 hurricanes. The most significant storm of the 2000 season was Hurricane Keith, which caused numerous fatalities and was blamed for large amounts of damage in Belize, Nicaragua, and Honduras. The 2001 season was an unusual year, with no storms actually making landfall in the United States. However, even though the eye never moved over U.S. soil, Hurricane Allison still caused widespread flooding in Houston, Texas. Hurricane Iris caused major damage in Belize when it made landfall there as a Category 4 storm. Hurricane Michelle was also a severe storm, causing numerous deaths and major damage in Jamaica, Cuba, Honduras, and Nicaragua. During the first 21 days of September 2002, there were 8 newly formed storms, which made that month a record. The 2003 Atlantic hurricane season was another record-breaker. Traditionally, the hurricane season runs from June 1 through November 30. However, in 2003, Storm Ana formed on April 20th, which launched the season early for the first time in fifty years. During 2003, there were 21 tropical cyclones, 16 of which formed into named storms and 7 of which reached hurricane status. The strongest of these was Hurricane Isabel, which formed near the Lesser Antilles and landed in South Carolina as a Category 2 hurricane. Isabel caused $3.6 billion in damage and was blamed for 51 deaths in the Mid Atlantic region of the United States. The 2004 hurricane season was another extended year, with the season extended into December. Hurricane Otto was responsible for this extension, with the storm lasting two days into the month of December. 2004 was also noted as one of the most costly and deadly years on record, with 3,132 deaths and roughly $50 billion U.S. dollars in damage caused by hurricanes and tropical storms. The 2005 Atlantic hurricane season was noted as "most active," with 5 storms making U.S. landfall: Dennis, Emily, Katrina, Rita, and Wilma. The most catastrophic effects of the season were felt in New Orleans and neighboring areas of the Louisiana coast when a 30-foot storm surge from Hurricane Katrina caused widespread flooding and deaths. The 2006 Atlantic hurricane season was a much less active season than 2005. Like 2001, it was an unusual year in that no hurricanes actually made U.S. landfall. In 2007, the season was off to an early start with the formation of subtropical storm Andrea on May 9, 2007. The season also ran late that year, with tropical storm Olga developing on December 11, after the season was officially over. Overall damage was estimated at $7.5 billion U.S. dollars, and the death toll was recorded at 416. Also noteworthy is the fact that 2007 was one of four years that had more than one Category 5 storm. 2007 was also the second season on record in which more than one storm made U.S. landfall on the same day (Felix and Henrietta). Are hurricanes and other tropical storms getting worse? Much of the U.S. public might believe so, particularly with the shock of Hurricane Katrina in 2005, which made headlines for many months after the storm. In fact, to this day, New Orleans has still not fully recovered from that storm. As to whether or not tropical storms are actually becoming more frequent and more severe, we're not really sure yet. One thing we do know is that record-keeping is far more accurate today than it was some fifty years ago. Only time will tell what the pattern of hurricanes may do in coming years. In the meantime, we can learn from the past by preparing ourselves for the future. Source: Free Articles from ArticlesFactory.com
