Jania R. Fernan Grade-7-Nitrogen July 30,2014 The Effects of Global Warming on Hurricanes There has been a noted increase in the number of hurricanes in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico since the mid-1990s. The long term average is that nine tropical storms will form per year, of which about five will become hurricanes. Since the mid-1990s the average has been fifteen tropical storms, of which eight became hurricanes. There has also been an upward trend in the concentration of the greenhouse gas carbon dioxide in the atmosphere and oceans due to mans activities over the past 100 years. During this time, hurricanes have gone through cycles where they have been more numerous, such as the cycle that we are experiencing now. Some scientists have drawn a one to one correlation between the earths temperature increase and the number of hurricanes and their intensity. As it was noted, the number one factor in tropical cyclone intensity is related to the atmospheric wind shear profile. Research is not conclusive that a small increase in the earths temperature would correlate with increased intensity and number of tropical cyclones. If the current trend of above average tropical cyclone activity were to continue for a considerably longer period, only then could the conclusion be drawn that warmer temperatures have played some part to cause an increase in tropical cyclone formation. tropicalweather.net/global_warmings_effects_on_hurricanes.htm
