While the study assumes the frequency and variability of tornadoes could increase in a warming world, the fact that there will be more homes and people in the path of tornadoes may be of greater concern. Stephen Strader of Villanova University's Department of Geography and the Environment, defines disaster as "a quantitative measure of the number of housing units potentially damaged or destroyed by a tornado."
In fact, the main concern is increased population in tornado-prone urban areas, the study said. By the end of the 21st century, the death and destruction caused by tornadoes in the United States could be three times higher, according to a study published in the peer-reviewed journal Climatic Change.Ĭlimate change is not the sole reason for the anticipated tripled disaster potential from tornadoes, however.
