The hurricane record for the past hundred years shows that the period from 1900 to 1950 had a higher average number of hurricanes than the period from 1950 to present. Many meteorologists have chalked this up to the effects of global warming changing the temperature of the oceans as well as wind patterns, but there is still a large amount of debate over the true causes of the shifts in weather events such as hurricanes.
It has been a pretty active year (2010) in the Atlantic Basin at least. Much of this can be attributed to the La Nina that we currently have, which tends to reduce the amount of wind shear encountered by these storms. It essentially makes it a little bit easier for them to get organized and strengthen, but it is by no means the only reason for the patterns we see in Atlantic hurricanes for this or any other year.
First the statistics for the North Atlantic:
Three of the six most powerful hurricanes ever recorded in the Atlantic basin (Katrina, Rita, Wilma), including the most destructive hurricane in U.S. history (Katrina); the first time three category 5 hurricanes have ever been recorded in the same year in the Atlantic basin.
A quiet year with 2 major hurricanes (category 3 or above), none at level 5.
2 major hurricanes, both category 5; the first time 2 hurricanes made landfall as category 5 during the same season.
5 major hurricanes, none at level 5.
The year 2006 was the quietest year listed, and corresponded with a El Nino event, which typically corresponds with lower hurricane activity in the Atlantic, although this year was somewhat more active than would otherwise be expected during an El Nino event. Another factor calming the Atlantic in 2006 might have been extremely large dust storms that covered the tropical Atlantic Ocean in the early summer of 2006.
The year 2008 had a quite high number of major Atlantic storms at category 3 or 4, but none at category 5. Statistically it would be hard to conclude anything from this data, since category 3 and 4 hurricanes were up, but category 5 hurricanes were down.
The years 2005 and 2007 set new records for hurricane activity. 2005 was the first time three category 5 hurricanes have ever been recorded in the same year in the Atlantic basin; 2007 was the first time 2 hurricanes made landfall as category 5 during the same season. This suggests that apart from year-to-year fluctuations, there could be an upward trend in category 5 hurricane activity.
Based on this limited range of observations and analyses, category 5 hurricanes have decreased in number during some years because of normal short-term fluctuations against a long-term upward trend.
El Niño causes increased wind shear over the Atlantic. Wind shear is a condition in which the speed and direction of wind changes with altitude. This condition disrupts the structure of tropical systems, preventing them from organizing and strengthening into hurricanes. It can also cause already existing hurricanes to degenerate.
We have better warnings that allow people to evacuate or take cover. Additionally, some town and cites, such as Galveston, Texas, have seawalls to protect from the storm surge of a hurricane.
Earthquakes have caused more deaths than hurricanes, and hurricanes have caused more deaths than lightning.
i assume hurricanes cause more deaths since I know for a fact that more people die of lightening strikes than shark attacks and there aren't very many of them. Sorry if this doesn't help. try searching 'natural disasters'. NRBB
theres no difference between the past hurracains and the present hurracains
Italy does not have hurricanes. Hurricanes form over tropical waters.
Hurricanes and tornadoes are two storms that are often confused, though they are very different from a scientific pserpective. They are the two most violent types of storm on Earth. Some hurricanes spawn tornadoes when they hit land, though these tornadoes are generally weaker than those spanwed by other systems. Hurricanes often cause major flooding when they strike. In fact, 90% of all hurricane deaths are drownings.

There are fewer childhood deaths now as it relates to illness and disease. Better medical care has saved many lives of children. There are still many childhood deaths related to accidents.
Mostly in the Atlantic Oceans or Gulf of Mexico. The Pacific Ocean generates far fewer hurricanes than does the Atlantic Ocean.
The five worst hurricanes in United States are: 1. Galveston Hurricane was responsible for 8,000 deaths. (1900) 2. Great Okeechobee Hurricane was responsible for 2,500 deaths. (1928) 3. Chenier Caminada Hurricane was responsible for 2,000 deaths. (1893) 4. "Sea Islands" Hurricane was responsible for 1,000 to 2,000 deaths. (1893) 5. Hurricane Katrina was responsible for 1,836 deaths. (2005)
Most of the deaths inland areas caused by hurricanes are from flooding that results from torrential rain.
Research shows that it will reduce gun deaths. States and countries who have passed gun laws have fewer deaths.
yes
Many hurricanes every year go through their life cycle without causing deaths.

YES
Birthrates drop, and may even drop low enough to reverse population growth. There are fewer infant and child deaths.
There is always room for change, even when it comes to hurricane laws. Current laws about hurricanes that are good for today may not be the best laws for hurricanes down the road.
