Al Gore says one thing, the peer-reviewed science says another.
Since [[air]] tends to move from areas of high pressure to areas of low pressure, creating wind. In the Northern Hemisphere, the earth's rotation causes the wind to swirl into a low-pressure area in a [[counterclockwise]] direction. This effect of the rotating earth on wind flow is called the [[Coriolis effect]]. The Coriolis effect increases in intensity farther from the equator. To produce a hurricane, a low-pressure area must be more than 5 degrees of latitude north of the equator. Hurricanes seldom occur closer to the equator. For a hurricane to develop, there must be little wind shear, or in other words, little difference in [[speed]] and direction between winds at upper and lower elevations. Uniform winds enable the warm inner core of the storm to stay intact. The storm would break up if the winds at higher elevations increased markedly in speed, changed direction, or both. The wind shear would disrupt the budding hurricane by tipping it over or by blowing the top of the storm in one direction while the bottom moved in another direction.

==Historical trends==
*Al Gore and other climate alarmists claim that the increase in major Atlantic hurricanes over the past decade or so, which they portray as truly unique, has been driven by what they call unprecedented CO2-induced global warming. This view, however, can now be seen to be not only incredibly myopic but downright wrong, for there have been many such increases in major Atlantic hurricanes over the past quarter of a millennium that have had nothing whatsoever to do with either rising atmospheric CO2 concentrations or increasing air temperatures.
