Will the number of hurricanes sink? by Martina Harvanova

It always has been sympathetic to me when I saw people trying to find something positive on black issues. Global warming is definitely deemed as one of them. On the first sight, you may think what an advantage of such a worldwide natural threat could be. Well, a scientist of the National Oceanic and Atmospheric Administration's Miami Lab and the University of Miami, Chunzai Wang, thought out one of its pluses. His latest study states that global warming could in fact reduce the number of hurricanes that hit the U. S. Although a new federal research clashes with previous studies in a great deal, Wang is sure his argument meet a clear explanation. As he claims in Geophysical Research Letters, the warming-up of the Indian and Pacific Ocean causes the creation of a vertical wind shear in the Atlantic Ocean. And exactly that has an effect on the wind speed and direction change that prevent the American coast from the intensification of the hurricanes. Therefore the final statement deposes "global warming may decrease the likelihood of hurricanes making landfall in the United States." The justification refers to number of observations and empirical researches. On the other hand, the vast majority of scientific community doesn't believe the study, moreover, they strictly reject it as they suppose the study is based on poor information and reflects just a small percentage of storms and similar natural disasters over the world. Hurricanes tend to be called "engines of destruction". They are giant, spiraling tropical storms that can pack wind speeds of over 160 miles (257 kilometers) an hour. The Atlantic Ocean's hurricane season peaks from mid-August to late October and averages five to six hurricanes per year. Their ability to generate energy on a staggering scale and its highly destructive winds represents one of the greatest dangers of nature to humans. The only defense against them is to an accurate weather forecast that gives people time to get out of its way. Also the U. S. as the strongest nation is helpless when they occur. Scientists may discover all the circumstances that generate or follow the hurricanes, but they just are not able to avoid them. Unfortunately, no study will change it.
